GBC-120-6 MACURCO

Product Overview

The Macurco GBC-120-6 is a dedicated line-voltage Gas Boiler Controller interface panel pre-configured with six onboard 10A SPDT mechanical control relays. Operating on a 120 VAC power input, this system functions as an automated emergency shutdown hub designed to immediately kill boiler operations, close gas valves, or activate exhaust fans when hazardous toxic or combustible gas levels are breached. It supplies distributed operational power for up to four Macurco 6-Series standalone gas detectors (such as the CM-6 or GD-6). Housed inside a heavy-duty NEMA 4X weather-resistant enclosure, the panel coordinates multi-stage emergency shutdowns, handles manual safety latch resets, and triggers auxiliary notification devices within commercial and industrial mechanical spaces.

Key Features

• Six-Relay Matrix: Factory equipped with 6 independent 10A SPDT mechanical power relays, providing ample dry-contact pathways to cleanly isolate and shut down multiple boilers, pumps, or zone valves simultaneously.
• Line-Voltage Input: Engineered to run directly on a 120 VAC electrical line feed, managing downstream power delivery for up to 4 connected gas detectors.
• NEMA 4X Enclosure: Sealed inside an opaque polycarbonate NEMA 4X (IP66) housing that fully isolates internal terminals from boiler room dust, humidity, and moisture.
• Onboard Safety Signaling: Built with a loud 90 dBA internal audible buzzer alongside bright green (Power) and red (Alarm) status LEDs.
• Dedicated Signal Driver: Includes an integrated 24 VDC output driver to simultaneously supply power to remote audible horns or strobe warning combos during a gas trip.
• Manual Latching Reset: Features a front-panel reset push button to manually clear unlatched safety loops and restore boiler power once ambient air levels return to safe conditions.
