The 707520/... supply unit for transmitters is used to supply 2-wire transmitters. It provides the power for the transmitter, isolates the signal and passes it on to the output. The electrical isolation is provided between supply and intrinsically safe input, between supply and output, and between intrinsically safe input and output. The unit is intended for industrial application and complies with the corresponding European Standards for ensuring electromagnetic compatibility (EMC). In addition, the transmitter supply unit conforms to the Directives of EN 50 014 and EN 50 020 “Electrical apparatus for use in hazardous areas”. The input is factory-calibrated to 4 — 20mA, at the output there is a choice between the standard signals 0(2) — 10V and 0(4) — 20mA.The transmitter supply unit is built into a polycarbonate housing which can be readily clipped onto three different types of rail. Several units can be mounted close together, to save installation space.
