Germany Buerklin OHG plug Buerklin OHG model Buerklin OHG price

Buerklin OHG plug is a control module that can output signals or provide a switching 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 can provide a pair of passive normally open/normally closed contacts to control the equipment. Some manufacturers' modules can be configured via parameters for active output (such as GST GST-LD-8301), with corresponding dual input/output modules, multi-input/output modules, etc. During a fire alarm, the alarm controller activates external linked devices such as smoke exhaust valves, air supply valves, fire shutters, fans, and sirens through the output module, and can receive action confirmation from the devices. The output module is connected to the controller's loop bus and can be installed near the controlled equipment or inside the floor terminal module box. Electronic coding allows for on-site addressing. 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 logic, activating the required fire protection equipment; a confirmation signal is received after the device acts.

Buerklin OHG plug composition

The fieldbus control system consists of three parts: measurement system, control system, and management system, with the hardware and software of the communication part being its most distinctive feature. 1) Fieldbus control system: Its software is an important part of the system, including configuration software, maintenance software, simulation software, device software, and monitoring software. First, select the development configuration software and 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: Characterized by multi-variable high-performance measurement, enabling measuring instruments to have computing capabilities and other functions. Due to the use of digital signals, it offers high resolution, high accuracy, strong anti-interference, and anti-distortion capabilities, while also providing status information of instrument equipment to adjust the processing process. 3) Equipment management system: Provides 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, which is installed in the main computer to perform management functions, forming a comprehensive management system information database for field devices. Based on this, equipment reliability analysis and predictive maintenance are realized, changing passive management to predictable management and maintenance modes. The 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 to provide 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 for further processing. The client runs on a PC or workstation. The server runs on a minicomputer or mainframe, utilizing 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, and server operating software such as Lunix, os/2, Window NT. Application software databases, communication protocols, network management protocols, etc.

Buerklin OHG plug material

1) The material of the female or male terminal shall be copper alloy, or plated copper alloy, nickel, or nickel alloy. [Exception: If the structure of the electrical appliance or device permits, the female or male terminal may be plated sheet metal, or a non-plated but 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 crimped and separated from the terminal strip; in this case, the edge where the terminal connects to the terminal strip does not require plating. The standard terminals used in temperature and thermal cycling tests shall be tin-plated steel or corrosion-resistant steel, with a hardness of Rockwell 68 ± 5 according to the Rockwell 30T hardness scale. 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 must be used for testing. 2.3) According to the Rockwell 30T hardness scale, the hardness of standard terminals made of brass is 62 ± 7.

Buerklin OHG plug wiring method

1) Apply moderate force when tightening connections to prevent stripping the threads of bolts and nuts due to excessive force. Replace any stripped bolts and nuts immediately; do not proceed with compromised components. 2) When using a screwdriver to tighten or loosen screws, ensure the screwdriver tip fits tightly against the screw head before applying force 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 terminal blocks prone to loosening or poor contact, wire ends must be fastened in a "?" shape to increase contact area and prevent loosening. 7) When connecting wire ends or lugs, it is strictly prohibited to install non-copper or poorly conductive washers in between. 8) When connecting wire ends, the contact surface must be smooth and free of oxidation. When connecting lugs or copper bars, apply conductive paste to the cleaned contact surface before tightening. 9) When connecting temporary lines, single-strand soft wires should be folded once at the end before connecting to the lower terminal of the circuit breaker; single-core hard wires should be connected to the lower terminal of the circuit breaker in a "?" shape. 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 installed between the motor output leads and the connecting cables. 11) When wrapping cables or other equipment requiring insulation protection with insulating tape, the insulation layer must be wrapped from one end to the other with a 1/2 overlap ratio, making at least one round trip.
