RemoteDisplayModule
In cases where the SA3-S has to be mounted in an inaccessible location where direct operation of the unit or
reading of the display is not possible, the SA3-Remote Display Module can be used to provide remote control
and monitoring of the SA3-S. The Remote Display Module is designed to be mounted on a DIN-rail in the con-
trol cabinet. It duplicates the SA3-S‘s built-in display and additionally provides a door-zone indicator and a error
reset switch.
