Belimo ZG-R01 Resistor the bimetal disc has failed

the bimetal disc has failed or the internal contacts are pitted

Key Benefits for Technicians Extended Compatibility: Increases the standard LF actuator shaft diameter capacity to accommodate 1/2-inch to 3/4-inch round or square shafts

Ensure the FLA and LRA ratings match the original equipment specifications to maintain system protection and electrical integrity across the control circuit

Installation Efficiency: Includes necessary mounting hardware to facilitate rapid field replacement for service calls

Worn blades lead to "scram" or ice buildup on the cylinder walls

Belimo ZG-R01 Resistor the bimetal disc has failedThe 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
