A current signal of 4 mA ... 20 mA proportional to the temperature is available at the output. The parameterisation occurs via software in accordance with VDI/VDE GMA 2187. The input is galvanically isolated from the output, the programming output and the power supply. The PC's serial interface is galvanically isolated from the programming input by connecting the K-ADP1 program adapter. The isolation of the programming jack from the input makes programming during operation and through a connected measurement circuit possible. Internal or external cold junction compensation may be selected by using thermocouples. The reaction to fault signals is programmable (up or downscaled output). A fault is indicated by a red flashing LED per NAMUR NE 44. Function 2 Subject to reasonable modifications due to technical advances.

Each power feed module monitors and provides protection for groups of as many as 100 individual devices. The PR-03 Power Rail is an insert component for the DIN rail. The UPR-03 Power Rail is a complete unit consisting of an electrical insert and an aluminium DIN rail measuring 35 mm x 15 mm x 2000 mm. The devices are simply snapped in place to make electrical contact. If a Power Rail is not being used, power can be supplied to the devices directly through the device terminals.
