Description
The Johnson Controls M9203-BGA-RK is a direct-mount electric spring-return damper actuator - 27 lb·in (3 N·m), AC/DC 24 V, on/off (two-position) control, with no auxiliary switch and a 3 ft. (0.91 m) cable. In Johnson Controls' words: "The M9203-xxx-RK Series Electric Spring-Return Actuators provide control of dampers in HVAC systems. All actuators in this series provide 27 lb·in (3 N·m) rated torque. A mechanical spring-return system provides rated torque with and without power applied to the actuator." Published specification: * Rated torque: 27 lb·in (3 N·m), running and spring returning, at all operating temperatures * Control: On/off (two-position) * Supply: AC 24 V (19.2 to 28.8 V) 50/60 Hz, or DC 24 V * Power consumption: 5 VA running, 1.6 VA holding (AC); 2.8 W running, 0.8 W holding (DC) * Minimum transformer size: 6 VA per actuator * Runtime, power on: 53 to 71 seconds for 90° at room temperature; 60 seconds nominal at full rated load (0.25 rpm) * Spring return time: 19 to 23 seconds at room temperature; 22 seconds nominal at full rated load; 28 seconds maximum at -22°F (-30°C) * Rotation range: 95° maximum full stroke; adjustable stop 35° to 95° * Shafts: round 1/4 to 1/2 in. (6 to 12 mm) * Electrical connection: 3 ft. (0.91 m) UL 758 Type AWM halogen-free cable, 18 AWG conductors, ferrule ends * Conduit: integral 1/2 in. (13 mm) threaded conduit connectors * Life cycles: 60,000 full-stroke cycles at 27 lb·in load * Audible noise: <36 dBA running, <20 dBA holding, <51 dBA spring returning, at 1 m * Auxiliary switch: none - see the M9203-BGB-RK * Warranty: 5-year "RK" is a separate Johnson Controls product line, not a variant label. Johnson Controls publishes the M9203-xxx-RK Series under its own document (LIT-1900999) alongside, but distinct from, the M9203-xxx-2(Z) Series. The torque, control type, runtime, spring return times, power consumption and noise ratings all match the equivalent M9203-BGA-2 - but the cable length does not. The difference that matters on site: the cable is shorter. The RK models are supplied with a 3 ft. (0.91 m) lead. The standard M9203-BGA-2 is supplied with a 48 in. (1.2 m) lead. That is about four inches less reach. On a factory-mounted damper it is ample; on a retrofit where you are reaching to an existing junction box it may not be. Measure before you substitute one for the other. Two-position only. A B model drives open on power and spring-closes on loss of power. There is no floating-point input and no analogue input. Note that the RK series is published with a narrower model list than the -2 series - on/off and proportional only, with no floating-point option. Spring return means fail-safe. Johnson Controls rates the full 27 lb·in with and without power applied, so the spring closes the damper against its seal in 19 to 23 seconds at room temperature, and no more than 28 seconds even at -22°F (-30°C). Direction is set by mounting: with actuator side A away from the damper you get counterclockwise spring return, with side B away, clockwise. Other features: direct-coupled design with universal clamp and no damper linkage required, reversible mounting, electronic stall detection, integral cable with coloured and numbered conductors, plenum rated models, double-insulated construction, UL / CE / C-Tick compliance, and manufacture under ISO 9001 quality control standards. * Brand / Manufacturer: Johnson Controls * Model / Part Number: M9203-BGA-RK * Series: M9203-xxx-RK Series electric spring-return actuators * Torque: 27 lb·in (3 N·m) * Control: On/off (two-position) * Runtime: 53 to 71 seconds; 60 seconds nominal * Supply: AC/DC 24 V * Auxiliary switch: None - see the M9203-BGB-RK * Cable: 3 ft. (0.91 m), 18 AWG * Spring return: Yes - fail-safe * Condition: New We stock both the M9203-xxx-RK and M9203-xxx-2(Z) ranges, plus crankarms, remote and universal mounting kits, weathershields and ball valve linkages. Tell us the damper and how far the actuator sits from the junction box and we will confirm which lead length you need.
