PLC actuator series
PLC actuator series: Interface between the PLC and actuators
When used as an interface between the PLC and actuators, only one N/O contact function is normally required. Ideal for 2-wire output field devices, including small motors, contactors or solenoid valves.
In such cases:
- The PLC … ACT output relay is used
- All actuator connections – including the load return line – are connected directly to the relay base
- This eliminates the need for additional output terminal blocks – saving time, space and money
