Honeywell C7061F2001 Replacement/Upgrade for RM7800

Product Overview

Honeywell C7061F2001 Replacement/Upgrade for RM7800 – Seamless Transition & Legacy System Compatibility

The Honeywell C7061F2001 is a proven UV flame detector engineered for direct integration with the RM7800 Series Relay Modules and the broader Honeywell 7800 SERIES Burner Management System (BMS) platform. As original equipment reaches end-of-life or becomes increasingly difficult to source, facilities running legacy combustion control architectures — including older R7847A, R7848A, and R7849A amplifier modules — face mounting pressure to qualify a reliable, drop-in replacement that preserves existing wiring, panel space, and safety logic without triggering a full system redesign.

This listing provides a fully tested, in-stock C7061F2001 unit ready for immediate dispatch. Whether you are replacing a failed detector on a gas-fired boiler, a dual-fuel burner, or a process heater controlled by a RM7800L or RM7800G relay module, this detector restores flame-sensing continuity with zero modification to your existing conduit runs or terminal block wiring.

Seamless Upgrade Solutions

A successful migration from an aging burner management architecture rarely involves a single component. In practice, engineers replacing a C7061F2001 are simultaneously auditing the condition of the RM7800L Relay Module that processes the UV signal, the R7847A Amplifier that conditions the flame-current output, and the S7800A1001 Display Module used for local diagnostics and lockout reset. If the control cabinet also houses a Q7800A Wiring Subbase, confirming its terminal integrity before inserting the new detector prevents nuisance trips during commissioning.

For facilities upgrading from older single-burner panels to a networked combustion management architecture, the C7061F2001 is fully compatible with systems that incorporate the RM7840L multi-burner relay module and the BC7000 Burner Controller platform. Engineers migrating DCS-supervised boiler trains often retain the existing UV detector wiring while upgrading the relay and amplifier stack — a strategy that minimizes loop re-verification time and keeps the process online during phased retrofits.

Where combustion air proving or gas valve interlock circuits are part of the upgrade scope, the C6097A Pressure Switch and V4055 Gas Valve Actuator are commonly sourced alongside the flame detector to complete the safety chain. Similarly, facilities that have standardized on Honeywell’s Excel 5000 or EXCEL Web building automation controllers for boiler sequencing will find that the C7061F2001 integrates without any changes to the BACnet or LON supervisory layer, since flame detection remains a hardwired safety function independent of the network protocol.

Retrofit Guidance FAQ

Q: Can I replace a C7061A or C7061B with the C7061F2001 without rewiring?
Yes. The C7061F2001 uses the same 1-inch NPT mounting thread and identical terminal designations as the C7061A and C7061B families. No conduit modification or terminal re-labeling is required.

Q: Will the RM7800 relay module require re-programming after detector replacement?
No. The RM7800 Series relay modules store safety timing parameters in non-volatile memory tied to the amplifier configuration, not the detector. Swapping the C7061F2001 does not alter trial-for-ignition timing, lockout thresholds, or purge cycles.

Q: Is the C7061F2001 compatible with both gas and oil burner applications?
Yes. The UV sensing tube responds to the UV radiation produced by both natural gas and fuel oil flames, making it suitable for dual-fuel burner configurations without detector changeover.

Q: What is the recommended commissioning check after installation?
After mechanical installation, perform a flame-signal strength check using the S7800A Display Module or a calibrated microammeter at the R7847A amplifier terminals. A reading above 1.0 µA DC confirms reliable UV detection. Conduct a simulated flame-failure test to verify lockout response within the relay module’s specified safety time.

Q: Can this unit be used in a redundant or cross-limit flame supervision architecture?
Yes. When paired with a second UV or IR detector channel through the R7849A dual-input amplifier, the C7061F2001 supports cross-limit flame supervision configurations required by certain insurance and process safety standards.

Warranty Assurance

Every C7061F2001 unit shipped by TOPNLMS carries a 12-month warranty covering manufacturing defects and functional failure under normal operating conditions. Prior to dispatch, each unit undergoes a pre-shipment functional check including UV tube continuity verification and housing integrity inspection. Units are packed in anti-static, shock-resistant packaging suitable for international air and sea freight.

In the event of a warranty claim, TOPNLMS provides a replacement unit or full refund within the warranty period. Our after-sales team responds to technical inquiries within one business day. Expedited shipping options are available for critical plant shutdowns where minimizing downtime is the primary procurement driver.

Bulk procurement for MRO inventory programs, OEM integrators, and EPC contractors is supported with volume pricing, consolidated shipment scheduling, and documentation packages including test reports and country-of-origin certificates upon request.
