Macurco GBC-24-6 Gas Boiler Controller, 24V, 6-Relay

Protect personnel and assets with the Macurco GBC-24-6 Gas Boiler Controller, a purpose-built detector accessory that automatically shuts down boilers when hazardous gas is present. Designed for commercial and industrial boiler rooms, this Gas Boiler Controller offers 6 onboard relays with expansion capability to manage up to 8 boilers individually, giving facility managers precise control over shutdown sequences and reduced downtime. Operating on 24V AC/DC and housed in a NEMA 4X (IP66) polycarbonate enclosure, it withstands demanding environments while integrating seamlessly with existing alarm, surveillance, and monitoring systems.

The GBC-24-6 includes a 24VDC driver for horn/strobe outputs, an audible buzzer for immediate on-site alerts, and supports up to four Macurco detectors for turnkey gas detection and shutdown. Ideal for safety-conscious operations, it simplifies alarm integration, remote monitoring, and security workflows while helping meet regulatory and insurance requirements.
