Relay Outputs designed for switching AC or DC voltage. All Relay Outputs are independent of each other, except functional outputs for motor control. Relay Outputs parameters are listed in the module specification.
Wiring the relay SKC14-U2R1 and SKC14-U2R2 modules is shown in Figure
Note: Use automatic fuses for short-circuit protection. Use varistors to reduce spark of relay contacts, which increases their life and reduce noise in electric net.
Important! When reversing a motor by switching between two polarities, for protect a short-circuit of the power supply and a burn the relay from arc between opening and closing contacts, an additional relay (R3 for example) should be used to first disconnect the power source from motor.
