Introduction to ABB XVC768115 3BHB7211R115
The ABB XVC768115 (order number: 3BHB7211R115) is a high-performance digital input/output (I/O) module, renowned as the “signal expansion hub” for industrial automation systems, especially tailored for ABB ACS880 frequency converters . As a key product in ABB’s scalable I/O series, it integrates 16 digital input channels and 16 digital output channels, specializing in collecting on-site sensor signals (such as position, speed, and switch status) and transmitting control commands to actuators like motors and valves . This module plays a critical role in scenarios requiring extended I/O capacity, including factory automation production lines, power system monitoring, and manufacturing process control. Its compact design supports seamless integration with ABB ACS800/ACS880 drive platforms and third-party control systems, while industrial-grade protection mechanisms enable stable operation in harsh environments with temperature fluctuations (-25°C to +60°C) and electromagnetic interference .
