German RHEINTACHO plug RHEINTACHO model RHEINTACHO price

The RHEINTACHO plug is a control module that can output a signal or provide a discrete on/off signal to actuate controlled equipment when control is required. It can also receive feedback signals from the equipment to report to the host, making it an important component of fire alarm linkage systems. Input/output modules available on the market typically 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 double input/output modules, multi-input/output modules, and so on. In the event of 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. 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. It uses electronic coding 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 transmits the linkage control signal to the output module via the bus based on the pre-programmed procedure. The output module then activates the linked fire protection equipment, and an acknowledgment signal is received after the device acts.

RHEINTACHO plug introduction

Fieldbus is an open interconnection network that can interconnect with networks at the same layer or different layers, and can also achieve shared network databases. Fieldbus embodies the characteristics of distribution, openness, interconnection, and high reliability, which are precisely the shortcomings of DCS systems. DCS typically transmits signals one-to-one; the analog signals used have low precision and are susceptible to interference. Operators in the control room often find it difficult to adjust parameters and predict faults with analog instruments, leaving them in an 'out of control' state. Many instrument manufacturers define their own standards, resulting in poor interchangeability and single-function instruments that struggle to meet modern requirements. Furthermore, almost all control functions are located within the control station. In contrast, FCS adopts one-to-many bidirectional signal transmission. The digital signals used offer high precision and strong reliability, keeping equipment under remote monitoring and control by operators at all times. Users can freely choose devices from different brands and types for interconnection as needed. Smart instruments possess rich functions such as communication, control, and computation, and control functions are distributed among various smart instruments. Thus, we can see the significant progress of FCS compared to DCS. It is precisely due to these characteristics of FCS that it offers great advantages in design, installation, commissioning, and normal production: First, since intelligent front-end devices can perform relatively complex tasks, separate controllers and computing units are no longer needed, saving on hardware investment and footprint. FCS wiring is relatively simple, and multiple devices can be connected to a single transmission line, greatly reducing installation costs. Since field control devices often have self-diagnostic capabilities and can send fault information to the control room, maintenance workload is reduced. Meanwhile, users have a high degree of autonomy in system integration, allowing flexible selection of suitable manufacturer products. The overall system reliability and accuracy are also significantly improved. All this helps users reduce installation, usage, and maintenance costs, ultimately increasing profits.

RHEINTACHO plug features

Field control devices have communication functions, facilitating the construction of factory bottom-layer control networks. Open and consistent communication standards give the system openness and interoperability between devices. Standardization of function blocks and structures ensures interchangeability between devices with identical functions. Downgrading control functions to the field gives the control system structure a high degree of decentralization. Fieldbus brings automatic control devices and systems into the realm of information networks, opening up broader fields for application; multiple control devices can be connected to a single twisted pair, helping to save installation costs; it reduces maintenance expenses; improves system reliability; and provides users with more flexible autonomy in system integration.

RHEINTACHO 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 tightening or loosening screws with a screwdriver, ensure the screwdriver tip fits tightly against the screw head before applying force to prevent slipping, which can damage the screw and make removal difficult, especially for common circuit breakers in distribution boxes. 3) If you encounter bolts or nuts that are difficult to remove, do not act rashly to prevent deformation that would make removal even harder. Tap them appropriately or apply a screw loosening agent or dilute hydrochloric acid, then attempt removal after a short wait. 4) Do not use pliers to tighten or loosen bolts and nuts to avoid damage. When using an adjustable wrench, adjust the jaw opening correctly to prevent damaging or deforming the bolt or nut, which would make removal 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 secured in a '?' 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 washers or washers with poor conductivity 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 soft wires should have their ends folded once 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 washers with poor conductivity, such as galvanized nuts, flat washers, or spring washers, be inserted between the motor output leads 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 an overlap ratio of 1/2, ensuring at least one back-and-forth pass.
