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

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

PXN / R output loop powered.
