Belimo ZG-R01 Resistor

The Belimo ZG-R01 Resistor is a critical field accessory designed to provide seamless signal conversion for HVAC control systems. This 500 Ohm resistor (precisely rated at 499 ?) is engineered to convert a 4-20mA signal into a standard 2-10 VDC control signal, allowing the integration of current-loop controllers with voltage-driven modulating damper actuators. Built for durability and ease of installation, the resistor is encased in professional-grade heat shrink tubing and features 6-inch pigtail wires for rapid termination in the field.

As a veteran technician knows, maintaining signal integrity is paramount. The ZG-R01 serves as the direct replacement for 32006306-001/U, ensuring legacy systems remain operational with modern components. This 1/2 watt (often specified as 1/4W to 1/2W depending on the application) 4-20mA adaptor allows for precise proportional control without the need for complex external transducers. Whether you are retrofitting older pneumatic-to-electronic panels or commissioning new Belimo actuator accessories, this resistor provides a low-impedance solution for stable automation signal conversion across your building management system.

• Universal Compatibility: Facilitates the connection of 4-20mA controllers to any 2-10 VDC modulating actuator.
• Direct Cross-Reference: Verified field replacement for the 32006306-001/U, reducing downtime during service calls.
• Rugged Construction: Resistor is fully protected by heat shrink tubing to prevent shorts and environmental degradation.
• Simplified Wiring: Pre-attached 6-inch pigtail wires allow for quick splicing into existing control loops.
• High Precision: Utilizing a 499-500 Ohm tolerance specifically for HVAC signal conversion accuracy.

How do I install the ZG-R01 for 4-20mA to 2-10VDC conversion?
The resistor should be wired in parallel across the input signal (+) and common (-) terminals of the actuator to drop the 4-20mA current, creating the necessary 2-10V drop for the motor logic.

Is the ZG-R01 compatible with other brands besides Belimo?
Yes, while designed for Belimo actuators, this 500 Ohm resistor can be used with any control device requiring a 2-10 VDC input from a 4-20mA source, provided the input impedance matches.

Can this be used for multiple actuators in parallel?
Special care must be taken regarding input impedance when wiring in parallel. For multiple actuator setups, specialized resistor kits like the ZG-R05 may be more appropriate depending on the total load.
