PC6DIO - 6 Digital Input / 6 Output Module

The PC6DIO module is a 6 channel digital input and 6 channel digital output module.

The inputs are isolated from the logic by opto-couplers and are designed to be switched to positive (common negative). The inputs have internal counters associated with them. These counters are 32 bit counters allowing a count value from 0 to 4294967295.

The 6 digital outputs are open drain MOSFET (N-TYPE). The outputs may be used to drive lamps or external relays when more drive capability is required. The outputs are isolated from the logic and they share a common negative terminal.

The module plugs into a special bus connector which fits inside the DIN rail. The power supply voltage and the CAN bus signals are connected via this bus connector.

The CAN interface is electrically isolated and is compliant with ISO 11898.

The module has been equipped with status led’s which are used to indicate the status of the Inputs and communications. This visual indication assists with fault finding and diagnostics.

The CANopen node ID and bit rate can be setup by DIP switches or software.
