CAREL FCM0002000 Controller

The CAREL FCM0002000 is a compact two-input electronic control module designed to monitor and regulate key physical values—temperature, pressure, and humidity—in HVAC, refrigeration, and heating equipment. It supports two sensor inputs configured for 0–20 mA or 4–20 mA signals and provides a 0–10 V analog output to drive actuators or external devices, making it suitable for modulating fans, valves, and related components in cooling or heating circuits. Powered from 24 V AC/DC with a tolerance of -20% to +10% and 50/60 Hz, the unit is intended for DIN rail mounting with IP20 enclosure protection and an operating environment of 0 to 50 °C and up to 90% non-condensing humidity. CAREL currently positions this model as phased out, with replacement DN33B9MR20; for new designs or parts availability, consider the newer controller while this FCM0002000 may remain in service on legacy installations.
