Information About LRB24-EV
The LRB24-EV is an LR Series rotary actuator incorporating Belimo’s Shared Logic Technology for Energy Valve applications. It supports a default 2–10 VDC control signal, with 4–20 mA operation available through an external conversion resistor. An Ethernet connection provides access to the web interface for configuration and operating information. The actuator works with the matching valve and sensing components to support hydronic heating and cooling control.
Key Features:
- Modulating Operation: Adjusts compatible valve position in response to the control demand.
- Rated Torque: Delivers 45 in-lb for the specified valve application.
- Dual Power Compatibility: Accepts 24 VAC or 24 VDC power.
- Non-Spring-Return Design: Provides motor-driven positioning without mechanical spring-return operation.
- Analog Control Input: Uses a default 2–10 VDC command signal.
- Current Signal Option: Accepts 4–20 mA through an external ZG-R01 500-ohm resistor.
- Analog Feedback: Provides a default 2–10 VDC feedback output.
- Network Integration: Supports BACnet IP, BACnet MS/TP, Modbus RTU, Modbus TCP, and MP-Bus.
- Manual Override: Includes an external push button for manual gear disengagement.
- Electronic Protection: Provides overload protection throughout its operating rotation.
The LRB24-EV delivers the reliability and precision required for modulating valve positioning in compatible hydronic energy-management systems.
