C-IR-0303M is a module on the CIB bus, which contains 3 AI / DI inputs, 3 relay outputs with a switching contact (2 with a common input and 1 separately connected to the terminal board).
The module is suitable, for example, for supplementing the control of heating circuits - both for common installations in the field of M&R and for the OEM segment - variant addition of heating circuits for CP-2970 / CP-1970 used as a control system for heat pumps and similar devices.
