Product Introduction

HONEYWELL R7247C1001 is a solid-state plug-in rectification amplifier used in industrial combustion systems. It processes ultraviolet (UV) radiation signals from flame sensors to continuously monitor burner operation and ensure safe fuel combustion.This module features a dynamic self-check function and a 2-4 second flame failure response time. Field engineers must verify the exact part number suffix, as minor configuration differences between R7247 variants can cause critical safety lockouts.

Installation & Configuration Guide

Preparation (10 min)

• Lock out and tag out the main burner control power.
• Verify the replacement module matches the R7247C1001 specification exactly.
• Gather a #2 Phillips screwdriver and an anti-static wrist strap.
• Locate the amplifier socket on the flame safeguard control panel.

Removal (5–10 min)

• Attach the anti-static wrist strap to a grounded point.
• Carefully grip the edges of the existing amplifier module.
• Pull the module straight out of the socket. Avoid twisting the pins.
• Inspect the socket for heat damage or carbon buildup.

Installation (10 min)

• Align the new R7247C1001 module with the socket pins.
• Press down firmly and evenly until fully seated.
• Ensure the module is flush with the control panel.
• (I once saw a slightly misaligned pin cause a false flame-out signal during a critical startup test.)

Power-On & Test (10 min)

• Remove lockout devices and restore control power.
• Observe the module indicator LED. A steady green indicates normal flame detection.
• Initiate a burner startup sequence to verify signal processing.
• Simulate a flame loss to confirm the 2-4 second safety lockout triggers correctly.

Troubleshooting Quick Reference

• Module has no LED indicators: Check the control panel power supply. Measure for proper voltage at the amplifier socket. If absent, trace the backplane fuse.
• Flashing red LED: Indicates a flame failure or dynamic self-check fault. Inspect the UV sensor (C7012E/F) lens for soot or degradation.
• Intermittent false lockouts: Inspect the UV sensor cable for ESD damage or loose connections. Verify the sensor is properly aimed at the flame.
• Burner fails to ignite: Confirm the amplifier is fully seated. A mismatched hardware revision will prevent the controller from receiving the flame signal.
• Module runs hot to the touch: Check for blocked ventilation around the control panel. Ensure ambient temperature does not exceed 80°C (176°F).

Dimensions, Mounting & Wiring Notes

• Mounting Method: Plug-In Solid-State Socket
• Weight: 0.227 kg (0.5 lbs)
• Terminal Notes: Handle the module by the edges only. Avoid touching the socket pins to prevent ESD damage or bent connectors.

FAQ

Will this R7247C1001 work with my C7027 UV sensor?
No. This amplifier is specifically designed for C7012E/F and C7061A/F sensors. The C7027 uses a different amplification circuit. Always match the sensor and amplifier specifications.I installed the module but the burner won’t fire. What gives?
Check the UV sensor alignment first. The sensor must have a direct line of sight to the flame. Also, verify that the dynamic self-check is completing successfully during the pre-purge cycle.Do you have a lower price if I buy five of these?
Volume pricing applies. Send your exact quantity to our sales team for a formal quote. Lead times may vary based on current surplus inventory levels.Is this module factory sealed or refurbished?
This is New Surplus. It is factory sealed but may have been in warehouse storage. We perform a full functional test, including self-check verification, before shipping.What happens if the red LED stays on continuously?
Power down the burner immediately. A solid red LED indicates a confirmed flame failure or internal amplifier fault. Contact our support team with a photo of the LED status and your controller model.How long does shipping usually take?
We ship verified stock within 24 hours of payment. Transit times depend on your location and chosen freight carrier. Expedited options are available at checkout.Can you test this with my specific BC7000 controller?
We test against standard Honeywell flame safeguard baselines. If your system uses a legacy or custom configuration, send us the controller firmware version. We will note any known compatibility issues before you order.
