The family is made of the followings models:

• CPUES0* - blind expansion
• CPUEB0* - blind open frame expansion.

The expansions have the following kind of inputs and outputs:

• 4 analog inputs, of which 2 for NTC probes and 2 for NTC probes, 0-20 mA transducers, 4-20 mA transducers and 0-5 V ratiometric transducers
• 5 digital inputs for NO or NC contact
• 1 output for cut phase module EVDFAN1
• 6 digital outputs (relays).

There are mainly two versions of expansions, according to the kind of supported BUS:

• IntraBUS version
• CANBUS version.

C-PRO EXP MICRO case is 4 DIN modules and has been studied for DIN rail mounting.
