GB dispenser interface converter

PURPOSE


GB 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 GB interface converters can be applied for communication with following brands of fuel dispensers, which use 2-wire current loop for communication with control systems: AG Walker, ANGI International, Baransay, Batchen, Bennett, CFT Clean Fuel, COMPAC, EuroPump, Falcon, Fuelsis, Galileo, Gilbarco, Greenfield, Kalvacha, Kraus, Maser, Meksan, Mekser, PEC (Gallagher Fuel Systems), Petposan, Petrotec, Prowalco, Salzkotten, Tankanlagen Salzkotten, Wayne Dresser (USCL communication protocol), Yenen, others.

The GB interface converters have 2 board modifications:
