CTC08V Module

CTC08V is a CanBus module with CanOpen protocol mountable on a standard DIN rail, which provides 8 inputs for Iron-Constantan thermocouples or Nickel Chrome-Alumel thermocouples.

The space required for installation is minimized by the vertical design of the module.

For each input 2 wires are available to connect the device directly to the module.

It is possible to detect the interruption of the connection to the thermocouple.

A sensor near the edge of the module, close to the input pins, allows cold junction compensation measuring of the temperature in the junction between thermocouple and tin.

6 groups of spring-cage connectors are provided:

  1. One 4 points group, of which only 2 are used for 24 V power supply;
  2. One group of 8 connectors grouped in 4 independent subgroups of 4 connectors. Each subgroup provides these connections;
  3. One 8 points group for the CanBus line, connected in pairs with the following scheme:
    • left +24V_CAN
    • middle left GND_CAN
    • middle right CANH
    • right CANL
  4. Four 4 points groups for thermocouple connections with two points per channel.
