NZ dispenser interface converter

PURPOSE


NZ 2-wire interface converters (RS-485/RS-232 to 2-wire current loop and backwards) are intended for communication with dispensers using 2-wire current loop interface through interfaces:

The NZ interface converters can be applied for communication with following brands of fuel dispensers, which use 2-wire current loop for communication with control systems: Actronic, Agira, Batchen, Compac, Fuelquip, Intermech, PEC (Gallagher Fuel Systems), Rix, Transponder, others.
