German hengstler plug hengstler model hengstler price

hengstler plug is a control module that can output signals or provide a discrete on/off signal to actuate controlled equipment when control is required, while also receiving feedback signals from the equipment to report to the host. It is an important component of fire alarm linkage systems. Input/output modules available on the market typically provide one pair of passive normally open/normally closed contacts for controlling the equipment. Some manufacturers' modules can be configured via parameters for active output (e.g., GST GST-LD-8301), with corresponding dual input/output modules, multi-input/output modules, and others. During a fire alarm, the alarm controller activates external devices requiring linkage via output modules, such as smoke exhaust valves, air supply valves, fire shutters, fans, and alarm bells, and can receive action confirmation from the devices. Output modules are connected to the controller's loop bus and can be installed near the controlled equipment or within floor terminal module boxes. They support electronic coding for on-site address setting. The output control logic of the output module can be programmed according to project requirements. When the controller receives an alarm signal from a detector, it sends linkage control signals to the output module via the bus based on the pre-programmed routine; the output module then activates the required fire protection equipment, and an acknowledgment signal is received after the device operates.

hengstler plug composition

The fieldbus control system consists of three parts: the measurement system, the control system, and the management system. The hardware and software of the communication part are its most distinctive features. 1) Fieldbus control system: Its software is an important part of the system. Control system software includes configuration software, maintenance software, simulation software, device software, and monitoring software. First, select the development configuration software and the human-machine interface software for control operations. Through the configuration software, complete the connections between function blocks, select function block parameters, and perform network configuration. During network operation, the system collects data in real time, processes data, and performs calculations. It optimizes control and logical control alarms, monitoring, display, reports, etc. 2) Fieldbus measurement system: Its characteristics include multi-variable high-performance measurement, giving measuring instruments additional functions such as computing capability. Due to the use of digital signals, it has high resolution, high accuracy, strong anti-interference, and strong anti-distortion capabilities. It also provides status information of instrument equipment, allowing adjustments to the processing process. 3) Equipment management system: It can provide diagnostic information, management information, equipment operating status information (including smart instruments), and manufacturer-provided equipment manufacturing information for the equipment itself and the process. For example, Fisher—Rosemoune Company launched the AMS management system. Installed in the main computer, it performs management functions and can form a comprehensive management system information database for field devices. Based on this, equipment reliability analysis and predictive maintenance are realized, changing the passive management mode to a predictable management and maintenance mode. AMS software is based on a T architecture with the field server as the platform. Supporting modular, feature-rich application software on the field server provides users with a graphical interface. 4) Bus system computer service mode: The client/server mode is a popular network computer service mode. The server represents the data source (provider), and the application client represents the data user, which obtains data from the data source and further processes it. The client runs on a PC or workstation. The server runs on a minicomputer or mainframe, using the intelligence, resources, and data of both parties to complete tasks. 5) Database: It can organically and dynamically store large amounts of data and applications, achieving full data sharing and cross-access with high independence. Industrial equipment parameters change continuously during operation, resulting in large data volumes and high real-time requirements for operation and control. Therefore, a distributed and real-time database system capable of mutual access and operation is formed. Mature options on the market include relational databases such as Oracle, sybas, Informix, SQL Server; and real-time databases such as Infoplus, PI, ONSPEC. 6) Network system hardware and software: Network system hardware includes system management hosts, servers, gateways, protocol converters, hubs, user computers, and underlying intelligent instruments. Network system software includes network operating software such as NetWarc, LAN Mangger, Vines; server operating software such as Lunix, os/2, Window NT; application software databases, communication protocols, network management protocols, etc.

hengstler plug material

1) The material for female or male terminals shall be copper alloy, plated copper alloy, nickel, or nickel alloy. [Exception: If the structure of the electrical appliance or apparatus permits, the female or male terminal may be plated steel or non-plated corrosion-resistant alloy.] 2) If formed female terminals or trimmed male terminals appear in the form of a terminal strip, when the terminal strip is continuously fed into the processing tool, the terminals are curled and separated from the strip. In this case, the edge where the terminal connects to the strip does not need plating. The standard terminals used in temperature and thermal cycling tests shall be tin-plated steel or corrosion-resistant steel. According to the Rockwell 30T hardness standard, their hardness shall be Rockwell hardness 68 ± 5. Exception: If the female terminal is only suitable for connecting to male terminals made of copper alloy, then standard terminals made of C26000 copper alloy shall be used for testing. 2.3 According to the Rockwell 30T hardness standard, the hardness of standard brass terminals shall be 62 ± 7.

hengstler plug wiring method

1) Apply moderate force when tightening wired connections to prevent stripping the threads of bolts and nuts due to excessive force. Replace any stripped bolts and nuts immediately; do not continue working with compromised fasteners. 2) When using a screwdriver to tighten or loosen screws, ensure the screwdriver tip fits tightly against the screw head before applying torque to prevent slipping, which can damage the screw and make disassembly difficult, especially for common circuit breakers in distribution boxes. 3) If bolts or nuts are difficult to remove, do not act rashly to prevent deformation that makes removal even harder. Tap appropriately or apply screw loosening agents or dilute hydrochloric acid, then attempt removal after a short wait. 4) Do not use pliers to tighten or loosen bolts and nuts to prevent damage. When using an adjustable wrench, adjust the jaw opening properly to prevent damaging or deforming the bolts and nuts, which would make disassembly difficult. 5) A single terminal block allows connection of at most two wires of the same type and specification. 6) For terminals prone to loosening or poor contact, wire ends must be secured in a "U" shape on the terminal block to increase contact area and prevent loosening. 7) When connecting wire ends or lugs to each other, it is strictly prohibited to insert non-copper or poorly conductive washers in between. 8) When connecting wire ends, the contact surfaces must be smooth and free of oxidation. When connecting lugs or copper bars, clean the contact surfaces, apply conductive paste, and then tighten. 9) When connecting temporary lines, single-strand flexible wires should be folded once at the end before connecting to the lower terminal of the circuit breaker; single-core solid wires should be connected in a "U" shape to the lower terminal of the circuit breaker. 10) For motor wiring of 30KW and above, it is required that no poorly conductive washers (such as galvanized nuts, flat washers, spring washers, etc.) be inserted between the motor lead wires and the cable wires connecting to the motor. 11) When wrapping cables or other equipment requiring insulation protection with insulating tape, wrap from one end to the other with a 1/2 overlap ratio, ensuring at least one back-and-forth layer.
