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

Description

• 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.
• Active use 12 V 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).
• IM3-40B, IM3-80B in case type B are designed for mounting into a installation box.
