German Allied TelSis plug, Allied TelSis model, Allied TelSis price

Allied TelSis plug is a control module that can output a signal or provide a digital 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 Gulf GST-LD-8301). Corresponding types include dual input/output modules, multi-input/output modules, and more. 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. 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 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 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 a confirmation signal is received after the device acts.

Allied TelSis Plug Introduction

Fieldbus is an open interconnection network that can interconnect with networks at the same layer or different layers, and enables sharing of 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 reside in the control station. In contrast, FCS employs 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 feature rich functions such as communication, control, and computation, with control functions distributed across various smart instruments. Thus, we can see the significant progress of FCS compared to DCS. Due to these characteristics, FCS offers substantial 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 simpler, and a single transmission line can connect multiple devices, significantly 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. Overall system reliability and accuracy are also greatly improved. All this helps users reduce installation, usage, and maintenance costs, ultimately increasing profits.

Allied TelSis Plug Features

Field control devices feature communication capabilities, facilitating the construction of factory-level underlying control networks. The openness and consistency of communication standards ensure system openness and interoperability between devices. Standardization of function blocks and structures enables interchangeability among devices with identical functions. Distributing control functions to the field level provides the control system architecture with a high degree of decentralization. Fieldbus technology integrates automation devices and systems into information networks, opening up broader application areas; multiple control devices can be connected on a single twisted pair, reducing installation costs; lowering maintenance expenses; improving system reliability; and providing users with greater flexibility in system integration.

Allied TelSis 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 continue using them. 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 disassembly difficult, especially for common circuit breakers in distribution boxes. 3) If bolts or nuts are difficult to remove, do not act rashly to avoid deformation that makes removal even harder. Tap them 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 avoid damaging or deforming the bolts and nuts, which would make disassembly difficult. 5) A single terminal block allows connection of up to 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 together, 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, soft single-strand wires should be folded once at the end before connecting to the lower terminal of the circuit breaker; solid single-core wires should be connected in a '?' 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 cables 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 layer.
