Boiler EC-BOM-G009HLA005 Replacement for EC-BOM Series

Product Overview

Boiler EC-BOM-G009HLA005 Replacement for EC-BOM Series: Smooth Transition & Legacy System Compatibility

The Boiler EC-BOM-G009HLA005 is a flame detector module engineered for combustion safety and burner management applications within the EC-BOM control series. As legacy EC-BOM combustion controllers reach end-of-life or become increasingly difficult to source, facilities engineers and maintenance teams face mounting pressure to identify a verified, drop-in replacement that preserves existing wiring infrastructure, panel space, and burner management logic without triggering a full system redesign.

This module serves as a direct functional replacement for discontinued or aging EC-BOM-G009 series flame detectors. It is designed to slot into existing EC-BOM combustion safety panels with minimal modification, supporting a smooth migration path from older flame-sensing hardware to a current, in-production component backed by a 12-month warranty and pre-shipment functional testing.

Whether your facility operates a single-burner boiler or a multi-zone combustion system, the EC-BOM-G009HLA005 integrates with the broader EC-BOM platform — including EC-BOM ignition control modules, EC-BOM gas valve relay boards, and EC-BOM burner sequence controllers — without requiring reprogramming of the upstream safety PLC or DCS. The module’s signal output interface is compatible with standard 24 VDC safety relay circuits and can interface directly with Siemens S7-300/S7-400 digital input modules or Rockwell Allen-Bradley 1756-IB16 ControlLogix I/O cards used in hybrid combustion-PLC architectures.

Seamless Upgrade Solutions

A successful EC-BOM-G009HLA005 retrofit rarely involves a single component swap. In practice, combustion system upgrades proceed most smoothly when the surrounding hardware is evaluated in parallel. During the replacement process, engineers commonly address the EC-BOM ignition transformer module, which drives the spark igniter and must remain synchronized with the new flame detector’s response timing. Similarly, the EC-BOM gas valve solenoid relay board — responsible for opening and closing fuel supply valves based on flame confirmation signals — should be verified for contact rating compatibility with the G009HLA005 output.

For facilities integrating the EC-BOM combustion panel into a broader SCADA or DCS environment, the Siemens ET 200SP distributed I/O system or a Rockwell 1734 POINT I/O module can serve as the interface layer between the hardwired flame detector output and the plant-level control network. Where PROFIBUS DP is the site communication standard, a PROFIBUS DP/PA coupler may be required to bridge the EC-BOM panel’s relay signals into the process bus.

In multi-burner installations, the EC-BOM burner sequence controller — which manages light-off, purge, and shutdown sequences — must be confirmed compatible with the updated flame detector’s response delay characteristics. Facilities running older Honeywell RM7800 series burner controls or Siemens LME series flame controllers alongside EC-BOM hardware should document the interlock wiring before commencing the swap. A 24 VDC DIN rail power supply module with adequate current headroom is also recommended when replacing multiple EC-BOM modules simultaneously, as inrush current during panel restart can trip undersized supplies.

Finally, for sites where the EC-BOM panel feeds into a Mitsubishi MELSEC Q-series or iQ-R series PLC via digital input cards, the flame detector’s output signal level and contact configuration should be cross-checked against the PLC input module’s specifications — particularly for sink/source wiring polarity — before the replacement module is energized.

Retrofit Guidance FAQ

Q: Do I need to rewire the terminal block when installing the EC-BOM-G009HLA005?
A: In most cases, no. The EC-BOM-G009HLA005 is designed as a terminal-compatible replacement for the G009 series. Existing field wiring — sensor leads, relay output wires, and power supply connections — can typically be transferred directly to the new module’s terminal block without modification. Always verify wire labeling against the original panel drawing before energizing.

Q: Will the replacement module require changes to the PLC program?
A: No PLC program changes are required if the upstream controller is reading a hardwired digital input from the flame detector relay output. The EC-BOM-G009HLA005 presents the same contact-closure logic as the outgoing model. If your system uses analog flame intensity signals, confirm the output signal range (4–20 mA or 0–10 V) matches the original specification.

Q: Is the EC-BOM-G009HLA005 compatible with PROFIBUS or Modbus communication?
A: The flame detector module itself communicates via hardwired relay contacts, not fieldbus. PROFIBUS DP or Modbus RTU integration is handled at the upstream EC-BOM controller or PLC level. No fieldbus configuration changes are needed on the detector itself.

Q: How much panel space does the replacement module require?
A: The EC-BOM-G009HLA005 shares the same DIN rail mounting footprint as the outgoing G009 series module. No cabinet cutout modifications or additional DIN rail space is required. Verify clearance for cable routing if the replacement module has a slightly different connector orientation.

Q: Can this module replace a Honeywell or Siemens flame detector in a hybrid panel?
A: The EC-BOM-G009HLA005 is a brand-specific replacement for EC-BOM series combustion panels. While the relay output signal is electrically compatible with many third-party burner controllers, functional interoperability with Honeywell RM7800 or Siemens LME series controllers should be validated against the specific interlock wiring diagram before installation.

Q: What is the lead time and shipping arrangement?
A: In-stock units ship from Xiamen within 1–3 business days. International shipments are dispatched via DHL, FedEx, or UPS Express. Expedited air freight is available for urgent replacement scenarios. All units undergo pre-shipment functional testing before dispatch.

Warranty Assurance

Every EC-BOM-G009HLA005 unit supplied by TOPNLMS is covered by a 12-month warranty from the date of shipment. Prior to dispatch, each module undergoes a pre-shipment functional test to verify relay output operation, power supply acceptance, and signal integrity under simulated load conditions. Units that do not pass the test protocol are not shipped.

In the event of a warranty claim, TOPNLMS provides a replacement unit or full refund within the warranty period, subject to inspection of the returned module. Our after-sales response target is 24 hours for initial acknowledgment and 72 hours for resolution proposal. Replacement units for warranty claims are prioritized for same-week dispatch to minimize customer downtime.

For procurement teams requiring documentation, we can provide a test report, packing list, and commercial invoice with each shipment. Long-term supply agreements and blanket purchase orders are supported for MRO and spare-parts programs.
