Material number:
  • RS232 and RS485/RS422 usable in parallel
  • 2 digital channels, configurable as inputs or outputs
  • 2 digital inputs
  • Connection of barcode readers, ID systems and sensors on one module

Serial interfaces (barcode scanners for example) are often scattered throughout systems. This interface module from the remote X67 system is the optimal choice for this area of application: RS232 and RS485/RS422 connection options directly where they are needed, distributed on the machine or system.

In addition, there are digital inputs and outputs on the same module so that corresponding 24 V sensors/actuators can also be connected.
