MB-600L Fireye Module

Overview

The Fireye MB-600L is a high-performance replacement logic module designed for the Fireye Multi-Burner (MB) Control System. It acts as the brain of the system, housing a microcomputer that manages sequential logic, safety start-up, and shutdown circuitry for industrial and commercial burner management applications. As a critical component of the MB-600S series, it ensures precise execution of the combustion sequence while monitoring for safety interlocks and flame failures across multiple burners.

Features

• Microprocessor-Based Logic: Provides intelligent control of the ignition sequence, pre-purge timing, and safety monitoring.
• Configurable DIP Switches: Features internal DIP switches that allow technicians to select specific sequence functions, timing parameters, and system configurations.
• User Interface: Equipped with front-mounted reset, scan, and enter push-buttons along with status indicator lights for local diagnostics and control.
• Solid-State Reliability: Engineered with robust circuitry to withstand thermal stress and electrical noise common in industrial boiler rooms.
• Seamless Integration: Designed as a direct plug-in replacement module that mounts to the system motherboard for simplified maintenance and repair.

Specifications

• Model Number: MB-600L
• Supply Voltage: 120 VAC (+10%, -15%), 50/60 Hz (powered through the MB system)
• Operating Temperature: -40 degrees F to 140 degrees F (-40 degrees C to 60 degrees C)
• Power Consumption: 25 VA (for the complete MB-600S system)
• Flame Failure Response Time: 3 seconds (+/- 0.5 seconds)
• Selectable Pilot Trial for Ignition: 5, 10, or 15 seconds
• Purge Time Range: Selectable from 0 seconds to 60 minutes
• Approvals: UL recognized (US and Canada) and FM approved when used in a complete MB-600S system

Applications

The MB-600L logic module is specifically designed for use within the Fireye MB-600S Multi-Burner Control System. It is used in industrial process heating, such as ovens and furnaces, where up to 20 individual gas, oil, or combination burners are connected to a common valve train. This module is ideal for facility managers and HVAC professionals seeking a trusted OEM replacement to restore full logic functionality and safety oversight in commercial combustion systems.
