Siemens Expander with 8 inputs and 2 outputs, back tamper G3

The SPCE652.100 expander extends the SPC system via X-BUS with 8 wired zones and 2 fully programmable relay outputs. The zones and outputs on the expander function exactly as the zones and outputs on the SPC panel. Each zone can be configured for different zone monitoring requirements. The outputs are volt free relays that provide both NO and NC terminals allowing the greatest flexibility. The expander comes in a plastic housing with front and back tamper protection and features also an X-BUS status LED and on-board buzzer for easy device identification and extensive self-diagnostic capabilities.
