Product Details
Name: Screw signal relay module
Model: WDX-4PC/WDX-8PC/WDX-16PC/WDX-32PC/WDX-0801
Screw signal relay module is an integrated electrical component specifically used for signal transmission, status isolation, and logic transfer in industrial automation control systems.Screw signal relay module adopts a mature and reliable screw crimping wiring method and is designed specifically for signal links in control cabinets. It is widely used in core scenarios such as PLC signal transfer, fault status feedback, and equipment operation indication.
Screw signal relay module integrates the relay body, base, and protective components into one, supporting standard 35mm DIN rail quick clamping without the need for additional fixation; The screw wiring structure is suitable for various types of wires ranging from 0.14 to 2.5mm ², with stable clamping force and excellent vibration resistance. It is very convenient for on-site wiring and later maintenance. Most models are equipped with built-in LED status indicator lights, which can visually display the relay's on/off status, significantly improving the efficiency of fault diagnosis; The conductive part adopts silver alloy contacts, combined with input side continuous current protection circuit, with an electrical life of up to tens of millions of times. The coil and contact can achieve voltage isolation of more than 2kV, effectively blocking interference between different voltage levels and ensuring stable transmission of control signals.
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.
