The C-IT-0200I is a module on the CIB bus containing 2 analogue inputs. The inputs can be configured for measurement of resistance temperature sensors, thermocouples, resistance, voltage or current.

The module power supply (including powering the current loops 4 to 20 mA) is from the CIB. The module is in the version with a higher protection IP-65, in a box fitted with glands, the external dimensions are 125x100x38 mm.

Configuration of the measurement range is done by connecting the sensor to the relevant terminals and by setting the jumpers. Examples of connection of the terminals and configurations of the jumpers for various ranges are shown in Fig2.

Notes:

  1. The jumpers are always in horizontal position ( i.e. plugged in).

  2. The two-wire sensor 4-20 mA is supplied from the C-IT-0200I module internal supply with the approx. 24 VDC voltage (a passive two-wire sensor); it should be connected between the a and b terminals. The externally powered sensor 0-20 mA or 4-20 mA should be connected between the b and c terminals (only a passive module input).
