Product Details
Name: Signal relay module/plug-in
Model: WDX-4PC-01/WDX-8PC-01/WDX-16PC-01/WDX-8PC-OR/WDX-32PC-01/WDX-0801-01/WDX-16PC-OR
Plug in Signal relay module is the core component of industrial automation control.plug in Signal relay module mainly responsible for signal expansion, conversion, and amplification functions, which can effectively solve the problems of limited signal transmission distance and insufficient driving capability in industrial control systems. At present, it has been widely used in industrial automation assembly lines, CNC machine tools, building automation systems, power monitoring and other fields. Its core function is to establish a stable signal connection between the control end and the execution end, which can directly drive low-power execution components such as relays and small solenoid valves, providing reliable signal guarantee for the stable and orderly operation of the entire equipment.
Screw signal relay module covers multiple specifications of coil voltages (including common 24V DC/230V AC), and can provide 1-2 sets of conversion contacts. The maximum switching current covers different levels of 3-10A, suitable for various switching needs from small power signals to medium-sized loads. The UL 94 V-0 flame retardant shell, combined with IP20 protection level, can meet the requirements of industrial environments with a wide temperature range of -40 ℃~70 ℃. It is a cost-effective standardized component for reliable signal transfer and logic isolation in industrial control systems.
Features
Integrated Plug and Play: Adopting a standard rail base plug-in design, the relay body is separated from the wiring base, and fault replacement does not require rewiring. Maintenance can be completed by simply unplugging the old module and inserting a new one, greatly reducing downtime for maintenance.
Excellent anti-interference performance: The coil and contact generally achieve voltage isolation above 2.5kV, and most models have built-in surge absorption protection circuits, which can effectively block crosstalk between different voltage circuits and ensure stable transmission of weak control signals without false triggering.
Strong wiring adaptability: The universal screw crimping interface is compatible with 0.2~1.5mm ² multi specification signal wires, supporting on-site wiring needs of different wire diameters, with stable clamping force, and can withstand long-term vibration in industrial sites without loosening.
Intuitive and easy to troubleshoot status: Built in working status LED indicator light, which lights up when the relay is closed, allowing operation and maintenance personnel to recognize the working status at a glance, improving fault troubleshooting efficiency by more than 50%.
Main purpose
Expand the contact capacity for PLC output, achieve small signal control of high-power loads, and adapt to the drive switching of contactors, solenoid valves, small motors and other loads in industrial control systems;
Complete electrical isolation between control circuits of different voltage levels, such as the isolation relay between 24V DC control signals and 220V AC load circuits;
Transfer of fault signals in industrial equipment, output of operating status, and complete equipment condition feedback in conjunction with indicator lights or upper computer;
The logic signal switching and contact expansion in scenarios such as automated production lines, intelligent distribution cabinets, and new energy control cabinets are standardized signal relay components for industrial control systems.
