The R7120M are microprocessor-based integrated burner controls for automatically fired gas, oil, or combination fuel single burner applications. The R7120M system consist of a relay module, amplifier, and purge card. Options include keyboard display module (KDM), Data ControlBus Module, remote display mounting.
Functions provided by the R7120M include automatic burner sequencing, flame supervision, system status indication, system or self-diagnostics and troubleshooting.
The R7120 adds a blinking fault code function to the POWER LED on Alarm shutdown, and programmable postpurge using the S7800A1142 Keyboard Display Module (KDM).
Features:
- Functions provided by the R7120M include automatic burner sequencing, flame supervision, system status indication, system or self-diagnostics and troubleshooting.
- Plug in replacement for Fireye M series controls using the existing Fireye wiring subbase.
- Require ST7800 Purge Timer and appropriate R78XX Amplifier to complete the replacement.
Specifications:
- Voltage and Frequency: 120 Vac (+10/-15%), 50/60 Hz (± 10%).
- Power Dissipation: 10W maximum.
- Maximum Total Connected Load: 2000 VA.
- Fusing Total Connected Load: 15A Fast Blow, type SC or equivalent.
- Operating Ambient Temperature: -40°F to 140°F (-40°C to +60°C).
- Storage: -40°F to 150°F (-40°C to +66°C).
- Humidity: 85% relative humidity continuous, noncondensing.
- Vibration: 0.5G environment.
- Install the relay module where the relative humidity never reaches the saturation point. The relay module is designed to operate in a maximum 85% relative humidity continuous, noncondensing, moisture environment. Condensing moisture can cause a safety shutdown.
- Do not install the relay module where it can be subjected to vibration in excess of 0.5G continuous maximum vibration.
- The relay module is not designed to be weather tight. When installed outdoors, protect the relay module in an approved weather-tight enclosure.
- An S7800A1142, Keyboard Display Module (KDM), is required for the setup of the R7120M Post Purge Timing, and must be purchased separately.
- Manual reset is required following any safety shutdown. Manual reset may be accomplished by pressing the push button on the device or pressing the remote reset wired through an attached display or S7820 remote reset module.
- Approvals:
- cULus component listed: File No. MP268, Guide No. MCCZ.
- Federal Communications Commission: Part 15, Class B,
