Frequently Asked Questions
How do I wire a load to the relay contacts?
Connect your device’s supply line to the COM terminal, then run the output from NO for normally-off operation or from NC for normally-on. Use appropriately rated wiring and secure the terminal screws firmly.
Does this module support both high and low trigger signals?
Yes. The high-impedance controller pin and onboard pull-down circuit let you activate the relay by applying a 24 V high signal or by pulling the input low, preventing unintended switching.
How does the optocoupler improve module performance?
The built-in optocoupler and isolation trenches electrically separate the 24 V control side from the high-current load side, reducing noise, preventing voltage spikes, and protecting your microcontroller or PLC.
