Power supply/isolator/signal converter ZSP-41 ü Full galvanic separation of circuits (IN-OUT, IN-SUP, OUT-SUP) ü Ability to select input and output signals ü Ability to use input line to power a two-wire transmitter ü Casing can be fitted on a standard rail (TS35) Applications and functions The ZSP-41 provides galvanic separation of an input signal (4 ÷ 20 mA, 0 ÷ 20 mA, 0 ÷ 10 V, 0 ÷ 20 V) and converts it, through a separation system into an output signal. An additional input line may be connected to any two-wire transmitter to provide it with a 19 ÷ 24 V. The device is typically used to provide galvanic separation between the measurement circuits installed on an object, and the main section. Configuration, calibration The user can use switches to configure input and output s ettings for the following signals. Access to switches by removing the front panel. Isolator can be produced to support other input and output s ignals. Calibration is carried out using potentiometers.
