These input expansion units offer the ability to connect up to 8 sensors to a single safety relay input. Some modules also feature control outputs for indication of sensor operation back to a PLC.
- NO/NO or NO/NC Sensors Based on Model
- Up to 4 Control Outputs for Individual Sensor Evaluation
- Different Models for Different Relays.
- DIN Rail Mounting
One feature of these interface devices is the ability to wire up to 8 sensors back to a single input on the control relay. This drastically reduces wiring while adding versatility to the safety relays by offering additional sensor inputs. Plus these interfaces can be mounted in a control cabinet near the sensors while a single pair of outputs can be run back to the control relay.
