Introduction and specification

  • Module ID: 3
  • Fully isolated power and signals
  • Outputs can be disconnected with a relay
  • Termination resistor can be connected with a SSR relay

Inputs

  • IN_A: nc
  • IN_B: nc
  • IN_C: SWITCH - a HIGH signal switches the output relay ON and connects the outputs to the connector
  • IN_D: ID - Used to set the module ID
  • IN_E: nc
  • IN_F: TERMINATION - a HIGH signal enables the termination resistor between CAN High and CAN Low
  • IN_G: CAN_TX - Non-isolated TX pin for the CAN transceiver
  • IN_H: CAN_RX - Non-isolated RX pin for the CAN transceiver

Outputs

  • OUT_A: 5V isolated
  • OUT_B: GND isolated
  • OUT_C: CAN High (CAN +)
  • OUT_D: CAN Low (CAN -)

Software Modes

  • CAN
