Item description
This input module allows the direct connection of two thermocouples. Internal electrical isolation allows operation of grounded sensors.
The module automatically linearizes the entire temperature range.
Cold junction compensation is utilized to compensate for 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 buscoupler.
The shield (screen) is directly connected to the DIN rail.
