Flame Monitoring Features
The Honeywell RM7895B1013 accepts either UV or rectification flame sensors. The single flame amplifier processes signals from your chosen sensor type. Therefore, this controller suits most standard burner configurations. The flame response time adjusts from 0.8 to 3 seconds. Consequently, you can optimize the controller for different fuel types and firing rates.
Timing and Control Functions
This on-off primary control includes adjustable pre-ignition and post-ignition timers. The pre-ignition timer ranges from 4 to 30 seconds for purge cycles. The post-ignition timer spans 5 to 15 seconds for flame stabilization. Hence, the Honeywell RM7895B1013 accommodates most commercial and light industrial burner systems. Four relay outputs control the ignition transformer, fuel valve, pilot valve, and alarm circuit.
Safety and Energy Storage
The Honeywell RM7895B1013 includes a 330µF capacitor for short-term ride-through. This capacitor provides 100 milliseconds of hold-up time during power dips. Additionally, a lithium battery retains safety parameters for up to 3 years. Thus, the controller remembers its configuration even after extended power outages. The battery also maintains the real-time clock for event logging.
Installation and Wiring
You can mount the Honeywell RM7895B1013 on a standard DIN rail. Alternatively, secure it with M4 screws through its four mounting tabs. The unit uses 12-pin and 8-pin terminal blocks for all field connections. Use shielded cables for flame sensor wiring to prevent false signals. The Honeywell RM7895B1013 works seamlessly with the RMS-TSG-TZ-C static trip unit.
Environmental Durability
This on-off primary control operates reliably from -20°C to +60°C. It also withstands 90% relative humidity without condensation. The unit survives vibration up to 1g from 10 to 150 Hz. Therefore, the Honeywell RM7895B1013 suits boiler rooms, ovens, and industrial heating applications perfectly.
