Product features DIRECT CURRENT AND VOLTAGE INSULATED CONVERTER FOR RAILWAY APPLICATIONS PX24 / R

The PX24 / R module is designed for measuring direct current or voltage signals from rail vehicles. It converts the input signal into a unified isolated output signal 4..20 mA, 0..20 mA, 0..10 V, 0 .. ± 10 V or 0..20mA. It can process DC signals within a voltage range of ± 10 mV to ± 1500 V and a current range of ± 50 uA to ± 10 A. The module is generally used to measure the signals of medium voltage shunts and dividers. The output of the converter is an active signal isolated from the input and the auxiliary supply.
