MEC320C Fireye CHASSIS

Overview

The Fireye MEC320C is a compact, microprocessor-based chassis belonging to the MicroM series of modular flame safeguard controls. It is designed to provide automatic ignition and continuous flame monitoring for commercial-sized heating and process burners. This specific model features an integrated interface for the E500 communication interface and Modbus capability, allowing for advanced diagnostics and system integration. It is engineered to be backward compatible with existing Fireye M-Series, TFM, and UVM controls, providing a reliable upgrade path for burner management systems.

Features

• Microprocessor-based design eliminates dependence on discrete timing components for improved accuracy.
• Integrated communication interface for Modbus and E500 protocols, enabling remote monitoring and data acquisition.
• Local reset button for manual system recovery and troubleshooting.
• Backward compatibility with legacy Fireye M-Series II wiring bases and components.
• Supports plug-in amplifier and programmer modules for flexible system configuration.
• Incorporates smart diagnostic LEDs to indicate system status and lockout conditions.
• Optional alphanumeric display interface (ED510) for accessing burner cycles, hours, and lockout history.

Specifications

• Supply Voltage: 120 VAC (+10%, -15%) at 50/60 Hz.
• Power Consumption: 12 VA (Operating).
• Temperature Range: -40 degrees Fahrenheit to 140 degrees Fahrenheit (-40 degrees Celsius to 60 degrees Celsius).
• Humidity Range: 0% to 85% non-condensing.
• Vibration Resistance: 0.5G continuous vibration.
• Communications: Modbus RTU and Fireye E500 interface.
• Reset Type: Local and remote reset capability.
• Relay Outputs: Independent relay outputs on terminals 3 and 4.
• Shipping Weight: Approximately 3 lbs (1.4 kg).

Applications

The MEC320C chassis is primarily used in commercial and industrial combustion systems, including gas-fired and oil-fired boilers. It is compatible with MEP300, MEP400, and MEP600 series programmer modules, making it suitable for applications requiring early spark termination, pilot proving, and interrupted pilot sequencing. It is ideal for energy management environments where integration into a larger data acquisition system via Modbus is required to optimize combustion processes and monitor safety status.
