The Rosslare SA-23-B-2G is a dual channel long-range RF transmitter designed to operate with the Rosslare AY-L23G outdoor receiver. The G version works on 433.92 MHz and is used to send a programmed Wiegand 26-bit ID through the AY-L23G to your access controller, making it a practical solution for gated entry, parking access, and long-range door control. The device is powered by a 3V CR2450 and supports selectable range settings of 15 m or up to 70 m depending on installation conditions, with two buttons intended to trigger channel A or B behavior through the receiver.
