Description
This analog input module directly connects to two thermocouples. Internal electrical isolation allows operation of grounded sensors.The module automatically linearizes the entire temperature range.Cold junction compensation mitigates the clamping unit offset voltage over the 0–55°C operating range.A line break is indicated by a red LED. A green LED indicates readiness for operation and error-free communication with the coupler.The shield directly connects to the DIN-rail.The device is ideal for operation in extreme environments thanks to:An extended temperature rangeGreater immunity to impulse voltages and electromagnetic interferenceHigher vibration and shock resistance
