Binary inputs units IM3-20B, IM3-40B

Binary input units IM3-40B and IM3-80B are used for connection of 4 or 8 devices with potential-less contacts

(switches, buttons, switches of other design, PIR detectors, fire and gas detectors, etc.).

Part of the inputs can be used as a balanced for alarm detectors:

- IM3-40B – inputs IN1, IN2

- IM3-80B – inputs IN1 – IN5

Contacts of external devices connected to the inputs of the unit can be NO or NC - input parameters are configured in the software iDM3.

Within the internal ESS configured in the iDM3 software, inputs must be set to balance or double balance.

The units generate a supply voltage of 12 V DC/75 mA for powering external intrusion detectors, so they can power PIR detectors, fire and gas detectors.
