Information About S301-IRF-R123
The S301-IRF-R123 is a Honeywell Analytics refrigerant gas sensor module utilizing dual infrared sensing technology for stable and selective detection performance. It is compatible with Honeywell 301EM-20 controllers and SQN8X platforms, communicating via 4–20 mA output and RS-485 Modbus networks. The sensor operates on 22–27 VAC at 48 VA (50/60 Hz) or 22–38 VDC at 2 A maximum and supports transmitter distances up to 500 feet depending on configuration. Designed for multi-gas refrigerant monitoring, it provides a measurement range of 0–1000 ppm with a 20 ppm deadband and recommended 6-month calibration interval.
Key Features:
- Infrared Refrigerant Detection: Dual IR sensor technology for stable and selective gas monitoring.
- 0–1000 ppm Measurement Range: Suitable for low-level leak detection in mechanical spaces.
- 1 ppm Resolution: Enables precise gas concentration monitoring.
- 4–20 mA Output: Standard analog signal for integration with control systems.
- RS-485 Modbus Communication: Supports networked monitoring applications.
- Multi-Gas Compatibility: Detects R11, R12, R123, R125, R134A, and R22 refrigerants.
- Visual & Audible Alarms: LED status indicators and 65 dBA internal audible alert.
- NEMA 1 Enclosure: Designed for indoor commercial installations.
The S301-IRF-R123 delivers the reliability and precision required for refrigerant leak detection and environmental safety monitoring in commercial HVAC and industrial facilities.
