C-IR-0203M

CIB modules 15.03.2020 08:56 15.03.2020 08:56

The C-IR-0203M is a module on the CIB bus, which comprises of two universal analogue or binary inputs, two relay outputs with a changeover contact (each is separately terminated) and one output
optionally adjustable as analogue, with the range from 0 to 10 V, or with a PWM output with adjustable amplitude and frequency.

The C-IR-0203M is implemented in a 1.5M box (dimensions 11/2 of a single-phase circuit breaker) on a DIN rail.

Notes:

  1. The relay outputs DO1 and DO2 are fitted with relays with changeover contacts 16 A.

  2. The analogue output AO1 can be configured by a switch on the front panel either as a standard output 0 ÷ 10 V, or as an active output PWM with adjustable frequency 100 Hz to 2 kHz and with the amplitude 10 to 24 V.

Connecting the changeover contact of the relays on the module terminals.

Notes:

  1. The range AO1 (0 to 10 V or PWM) is set via the jumpers on the front panel and in the software configuration.
