Belimo 40155 Diode
As a critical electronic component for precision HVAC control, the Belimo 40155 Diode (specifically the IN4007) is the standard solution for converting signaling in complex actuator circuits. This rectifier diode is essential when integrating Belimo actuators with triac sink controllers or when configuring pulsed control signals from either the Hot (Source) or Common (Sink) 24V line. By ensuring proper current direction, the 40155 prevents compatibility issues where the actuator's internal common reference might otherwise conflict with the controller, specifically in floating point or modulating control applications. Whether you are servicing air handling units, fan coil units, or VAV box reheat coils, using the correct Belimo 40155 prevents "hunting" and stabilizes the control loop. This THT (Through-Hole Technology) component is the exact replacement part required to maintain cULus requirements in systems utilizing Characterized Control Valves (CCV) and damper actuators where an external rectifier is specified in the wiring diagram.
Key Benefits:- Ensures seamless triac sink controller compatibility with standard Belimo actuators.
- Facilitates accurate pulsed signal handling for 24V source and sink configurations.
- Critical for preventing feedback interference and maintaining stable signal modulation.
- Hardened IN4007 diode construction for high-reliability performance in industrial HVACR environments.
- Maintains system adherence to cULus electrical standards without additional grounding.
When is the Belimo 40155 required instead of direct wiring?
The 40155 diode is necessary when the 24V control signal is pulsed or when using a triac sink output, as it enables the actuator to correctly interpret the reference voltage without internal shorting.
Can I use a standard bridge rectifier instead of the 40155?
While functionally similar, the Belimo 40155 is the factory-specified IN4007 part number designed to meet exact impedance and mounting requirements for Belimo electrical accessories.
Does this diode affect position feedback signals?
Yes; it is important to note that position feedback cannot be used simultaneously with a triac sink controller even when this diode is installed, due to the incompatible internal common reference.
