MC120 Fireye Chassis

Overview

The Fireye MC120 is a 120 VAC, 50/60 Hz chassis designed for the Fireye Modular M-Series II Flame Safeguard Control system. It serves as the foundational base for compact, modular burner management systems that provide automatic ignition and continuous flame monitoring for commercial-sized heating and process burners. The MC120 is specifically engineered to be backward compatible with obsolete Fireye M-Series TFM and UVM controls, allowing for system upgrades without extensive rewiring. It acts as a central hub that accepts various plug-in amplifier and programmer modules to customize burner control functions.

Features

• Modular Design: Supports a variety of plug-in programmer and amplifier modules for complete versatility in control functions and timing.
• Backward Compatibility: Designed to replace older TFM and UVM series controls using the same existing wiring base.
• Safety Checking Circuit: Incorporates a built-in circuit that tests for real or simulated flame on every start; if a flame is detected during purge, the system locks out for safety.
• Status Indication: Compatible with programmer modules that feature LED indicator lights to show the current operating status of the control.
• Versatile Flame Detection: Supports flame monitoring via miniature UV scanners, flame rods, or photocell detectors depending on the selected amplifier.

Specifications

• Supply Voltage: 120 VAC (min. 102V, max. 132V), 50/60 Hz.
• Power Consumption: Approximately 12 VA during operation.
• Operating Temperature: -40 degree F to 125 degree F (-40 degree C to 52 degree C).
• Shipping Weight: Approximately 3 lbs (1.4 kg).
• Humidity: 0% to 95% relative humidity, non-condensing.
• Enclosure: Includes a dust cover to protect internal electronic components.
• Agency Approvals: UL listed and FM approved.

Applications

The MC120 chassis is used in commercial and industrial combustion systems to manage burners firing gas, light oil, or combination fuels. It is commonly applied in HVAC heating systems, process ovens, and boilers where automatic sequencing and safety monitoring are required. Because it supports interchangeable modules, it is ideal for applications requiring specific timings for purge, pilot trial for ignition (PTFI), and functions like relight or non-recycle operation. It is frequently used in the petrochemical, power generation, and pulp and paper industries.
