Features Input: 0(4) - 20 mA / 0 - 10 V DC, selectable Output: 0(4) - 20 mA / 0 - 10 V DC, selectable Input, output and mains galvanically separated Modular design Housing for DIN rail mounting 12-pole, 82 x 22.5 x 98.8 mm (h x w x d) Brief Description The active universal isolating amplifier HE 501 serves for the galvanic separation of measuring circuits, which are on different potential. The galvanic isolation is performed between input, output and auxiliary energy (24 V DC). The HE 501 processes input signals within the range of 0 - 20 mA, 4 - 20 mA or 0 - 10 V. With two switches at the top side of the device the input value is defined. The output signal is available at the same time as voltage signal (0 - 10 V) and current signal. With a switch in the front, the output current can be switched between 0 - 20 mA and 4 - 20 mA. The modular structured device allows a clear allocation of measuring circuits and corresponds to the EMV guidelines EN 50081 (Part 1) and EN 50082 (Part 2).
