CDI20 Module

CDI20 is an open frame CanBus module with CanOpen protocol mountable on a standard DIN rail, which provides 20 digital optocoupled inputs.

Inputs can be buttons, limit switches, proximity sensors, photocells, etc.

4 groups of spring-cage connectors are provided:

  1. 2 connectors for module 24 V power supply.
  2. 2 connectors for channels 24 V power supply (isolated from the module).
  3. 60 connectors for inputs with 3 connections for each input:
    • left: 24 V
    • middle: input
    • right: 0 V
  4. 6 connectors for CanBus line (CANH, CANL e GND_CAN input, CANH, CANL e GND_CAN output)

2-wires devices, like limit switches, can be directly connected between the middle and the left point, without any extra connector.

3-wires devices, like photoelectric cells and proximity sensors, can be connected directly to the 3 points respecting their own meaning, without any extra connector.

Channels power supply is protected by an electronic fuse against accidental shortcircuits.
