- Supply Voltage: AC/DC 24 V (50/60 Hz)
- Power Consumption: 0.3 W (Running) / 1 VA (Wire sizing)
- Control Signal Output (Y): Selectable 2…10 VDC or 0.5…10 VDC via internal slide switch
- Control Range: 0 to 100% of the actuator's rotation angle
- Mounting Style: Flush, front-panel mounting (Note: If you need surface mounting, look for the Belimo SGA24)
- Protection Class: IP40
- Wiring Terminals: Supports up to 1.5 mm² (14 AWG) wire max
- Remote Manual Control: Turning the manual rotary knob outputs a proportional signal directly to the actuator to adjust airflow manually. The physical rotation range of the knob can be limited mechanically using adjustable physical stops.
- Minimum Positioner Limit: When wired alongside an automatic master controller, the SGF24 acts as a "higher of two signal" selector. Whichever signal is greater—the automated controller or the manual positioner—is sent to the actuator, ensuring a minimum damper position is strictly enforced (e.g., for fresh air requirements).
- OEM Part Cross-References: It is also distributed directly through equipment manufacturers, such as under Greenheck Product #381657.
