Keyswitch expander with 2 leds and 3-position key switch

The spce110.100 is a universal key switch expander with 2 tri-color leds, a 3-position key switch and buzzer.
The freely programmable user interface indicates the configured status information with leds (e.g. key switch position, area setting states) and enables activation of application specific processes by changing the key switch position (e.g. unlock keypad or indication expander, setting of an area, open or close a gate).
The expander also provides one freely programmable volt free relay output with either no or nc terminal.
