The NRC-008 A GPO relay output module is a versatile DIN-rail unit designed to distribute output signals within the VARES-2000 system. It allows the switching of external devices such as mandatory call systems, acoustic indicators, alarm interfaces, or access controls. The module processes up to 8 GPO signals from the Network Control Center (NCC-2000 A) and outputs them as either potential-free relay contacts or—based on jumper settings—as mandatory call voltages.

Each of the 8 GPO channels provides two independent relay outputs (COM/NC/NO). Alternatively, a jumper setting allows switching the output to a fixed voltage output between 24 and 29 V (mandatory call). This dual-output capability per channel provides maximum flexibility for integration with external systems.

Housed in a compact plastic enclosure for DIN rail mounting, the module is ideal for fire protection systems, technical alerts, and interfacing with third-party equipment.
