Pluggable Compact PLC Relay

Is space and cost a concern for you when designing-in relays for automation?

Phoenix Contact’s PLC Relay eliminates the need for extra terminal blocks, helping you reduce both space and cost. Let us see how.

PLC Relay Actuator Series

Relay-Actuator Setup

In applications where only one normally-open(N/O) contact function is required, you can use Phoenix Contact’s PLC to Actuator output relays to interface with actuators, such as motors, contactors or solenoid valves.

You can connect all actuator connections, including the load return line, directly to the relay. Hence, eliminating the need for additional output terminal blocks to transfer power.

The benefit is daisy-chaining or looping the wiring for the power will not be necessary. This is illustrated in the wiring layout below.

Likewise, Phoenix Contact’s PLC to Sensor input relays can be used to interface with sensors, such as proximity switches, limit switches or auxiliary contacts, where only one normally-open(N/O) contact function is required.

Similar to the Actuator Series, you can also connect all sensor connections, including the supply voltage for the sensors/switches.

As you can see, available with screw, spring or push-in field terminals, Phoenix Contact’s relays will:

• Open up Space on the DIN rail
• Reduce Labor and components costs
• Eliminate an extra point of failure

Ultimately, you can save approximately 80 Pecent on your DIN rail and approximately 60 percent less time on installation.
