ACI QIRF-R404AX-0 : Refrigerant Sensor, R404a, 0-1000 PPM, 4-20 mA (4-wires) or 2 to 10 VDC (4-wires), 3 SPDT Relays, LCD Display, NEMA 4X Enclosure
The QIRF Refrigerant Gas Detectors are the second generation of a proprietary designed gas detector that is easily configured to meet the International Mechanical Code, ASHRAE 15 and B52 requirements. These transmitters are engineered to address the deficiencies inherent with solid- state sensors. Infrared technology facilitates specific gas type refrigerant detection without any cross-sensitive interferences. Standard features include a digital display, three user configurable relays, buzzer, horn/strobe output, NEMA 4X enclosure and non-intrusive calibration. Analog outputs of 4-20 mA and or 2-10 VDC are available along with RS-485 Communications that can be used with a Modbus RTU or proprietary OptoMux communication protocol for use with any of the standalone gas controller such as the Q4C, M-Controller or Q-Controller.
