PRODUCT INFORMATION Applications: * Refrigerant gas leak detection in air conditioning/refrigeration systems * Factory calibrated * Temperature compensation circuit * Resistant to interference gases * Compact embedded type module * Open collector output (monitoring/alarm/ malfunction output) * Meets IEC60335-2-40 requirements FCM2630-E00 is an embedded type module using the semiconductor gas sensor TGS2630 which is optimized to detect A2L refrigerant gas R-32. This module enables users to easily build a reliable gas leakage detection system by eliminating electronic circuit design for temperature compensation and the calibration process. In addition, a connector allows easy replacement of the gas sensor module for periodic maintenance. The TGS2630 gas sensor has a built-in filter to reduce the influence of alcohol and other interference gases, resulting in high selectivity to R-32. For more detailed information on the gas sensor, including sensitivity characteristics, see TGS2630 Product Information. FCM2630-E00 is capable of satisfying the IEC60335-2-40 Edition 6.0 Annex LL and the JRA4068:2016R (Performance 3) standards. The applicable standards are both limited to refrigerant gas type: R-32.

Operation state priority: ® Alarm © Malfunction © Initial © Monitoring (The output signals should be connected to external pull-up resistances.) NOTE 1: Once a gas sensor module is exposed to 10,000ppm or more of R-32, Alarm state is kept thereafter. Do not apply high concentration test gas equivalent to 10,000ppm or more of R-32 while evaluating gas sensor modules. Replace a gas sensor module if it is exposed to a high concentration R-32 gas because its normal performance may be no longer maintained. NOTE 2: If the internal temperature near the gas sensor module becomes higher than the external...
