Description
The GE V7768-320001 is an industrial-grade motor control module designed for HVAC and ventilation systems in power plants, factories, and large facilities. It integrates fan speed regulation and damper positioning via PID logic, optimizing airflow while reducing energy consumption. Compatible with GE’s Proficy® HMI platforms, it supports seamless integration into building management systems (BMS).
Features
- Multi-Protocol Control: Modbus RTU/TCP, BACnet/IP, and Profibus DP interfaces.
- Dual-Channel Output: Drives 3-phase motors (0.75–5.5 kW) and linear damper actuators (24V DC/AC).
- Dynamic PID Tuning: Auto-adapts to load changes with ±0.5% speed accuracy.
- Diagnostic Suite: Real-time monitoring of torque, temperature, vibration, and phase loss.
- Ruggedized Operation: Rated for -40°C to +85°C (-40°F to +185°F) and 100% humidity (non-condensing).
- Fail-Safe Modes: Defaults to pre-set speed/damper position on communication loss.
