UFC911B108 3BHE037864R0108 Digital Input Module

Product Overview

UFC911B108 3BHE037864R0108 is a digital input module (DI) in ABB industrial automation systems.
It is usually installed in control systems or distributed control systems (DCS) to collect on-site switch signals and convert the switch status of external devices (such as valve open/close, button press/release, limit switch action, etc.) into digital signals recognizable by the system.

This module is commonly used in ABB Symphony Plus, Advant OCS, Bailey Infi-90 and other series of control platforms to ensure stable connection between process control systems and field equipment.

Application scenarios

process control

Collect various on-site switch signals in industries such as petrochemicals, power, metallurgy, and papermaking, such as valves, actuators, and interlock switches.

Equipment status monitoring

Detect motor operation/stop, pump start/stop, and conveyor belt position limit.

safety protection

Cooperate with the Emergency Shutdown System (ESD) to receive emergency stop buttons or access interlock signals.

Factory Automation

As the input end of the automated production line, it collects workstation signals and sensor switch status.
