Frequently asked questions

Relay card or individual plug-in relays?

A relay card puts 4 or 8 relays, LEDs and terminals on one DIN-rail board, which is quicker to wire to a PLC. Individual plug-in relays in sockets are easier to replace one at a time and come in more coil and contact options.

Which coil voltage should I choose?

Match the coil to the signal that drives it: 24 V DC for PLC and sensor outputs, 230 V AC for mains control circuits.

Can a relay switch a motor directly?

Only very small loads. Use the relay to switch a contactor coil, and let the contactor switch the motor.
