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

To connect up to 2/4 devices with potential-free contact (PIR, button, etc.), 1 x thermo input TZ/TC, output for powering detectors 12 V DC/75 mA, mounting into an installation box

EAN: 8595188132305 | Code: 3230 standard

Binary input units IM3-20B, IM3-40B and IM3-80B are used for connection of 2, 4 or 8 devices with potential-less contacts (switches, buttons, switches of other design, PIR sensors, fire and gas detectors, etc.)

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

IM3-20B – inputs IN1, IN2
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 IDM.
The units generate a supply voltage of 12V DC/75 mA for powering external intrusion detectors, so they can power PIR detectors, fire and gas detectors.
Active use 12V DC output for powering detectors increases the nominal consumption of units from BUS (see technical data).
The units can be used for counting pulses of energy meters with pulse output.
The units are equipped with a temperature input for connecting an external two-wire temperature sensor TC/TZ (see accessories).
IM3-20B, IM3-40B, IM3-80B in case type B are designed for mounting into a wiring box.
