Introduction Return to top of page

The PCL-725 Relay Actuator and Isolated D/I Card provides eight electro-mechanical SPDT relays and eight opto-isolated digital inputs on a half-size card.

Its eight on-board SPDT relays are ideal for applications such as device ON/OFF control or low power switching. A red LED next to each relay signals its ON/OFF status for easy monitoring.

The PCL-725's eight opto-isolated D/I channels are ideal for digital input in noisy environment or with floating potentials.

You can configure each input channel individually by setting jumpers for either isolated or non-isolated input. An on-board DB-37 connector provides access to all input and output channels.

Applications

 

 

  • Digital signal and contact status monitoring

  • External relay driving

Features

 

 

  • Eight relay outputs
  • Eight opto-isolated digital inputs
  • LED relay status indicators
  • Isolated or non-isolated digital inputs
  • Male DB-37 matching connector included
