Honeywell R4343E1014 Flame Detector Relay.

1.General Description of r4343e1014 honeywell

The Honeywell R4343E Flame Relay Controllers include models like R4343E1014. These controllers are flame switch-type units. They work with compatible flame detectors. Their job is to monitor and show if there is a flame or ultraviolet radiation in burner systems.

The R4343E1014 Flame Relay Burner Controller is from the R4343E series. It works with UV-type flame detectors like the C7027, C7035, and C7044. It has two separate sets of SPDT (single-pole, double-throw) contact outputs. These outputs ensure reliable supervision and control of the burner flame.

The Honeywell R4343E1014 Relay Flame Detector is a flame switch for intermittent use. It offers accurate flame detection and quick response to flame failure for industrial or commercial burners.

Manufacturers design these relays for short-term use. People commonly use them in commercial and industrial combustion systems. They help ensure safe ignition and monitoring.

5.Installation Instructions of honeywell r4343e1014 230 vac 50/60hz relay flame detector

Important Notes

l Disconnect the power supply before performing any installation or wiring.

l Follow the burner manufacturer’s installation manual whenever available.

l If unavailable, follow the instructions below.

l For R4343E models, an internal quick-blow fuse provides protection for the connected flame detector.

Base Installation

l You can mount the base on any flat surface; I recommend vertical installation.

l Ensure sufficient space for relay removal and maintenance.

Base Wiring

l Wiring and overload protection must comply with local electrical codes.

l Before mounting the relay, verify that all wiring connections are correct.

Mounting the Relay

A. Insert the relay module firmly into the sub-base.

B. Tighten the two screws located on the relay’s front panel.

C. After installation, perform flame-current measurement as described in the operation procedure.

Flame Signal Monitoring

l The Honeywell R4343E1014 Flame Relay Switch has a front-panel socket. This socket lets you measure flame signal strength directly. You can use a Honeywell W136A microammeter or a similar tool for this.

l Typical readings depend on the type of connected UV flame detector and burner setup.
