Product Overview
The DSDI110A is a digital input board designed for industrial automation and process control systems. It primarily receives digital (ON/OFF) signals from field devices such as switches, sensors, and proximity detectors, and transmits them reliably to the control system for monitoring, alarms, and logic processing.
This module features high channel density, isolated inputs, and robust reliability, suitable for environments demanding high signal monitoring performance. It is designed to operate continuously under harsh industrial conditions, including electrical noise, temperature variations, and minimal maintenance requirements.

Product Description
The DSDI110A module is designed to handle industrial digital signal inputs. It collects up to 32 digital channel signals and transmits them to the control system. Each channel is optically isolated to prevent noise, ground loops, or potential differences, enhancing system stability and reliability.
It supports both polling scan (reading all channels periodically) and interrupt-triggered modes (reporting immediately when any channel changes), making it flexible for various control architectures. Its compact size and lightweight design make it easy to install in cabinets or racks.
DSDI110A is widely used to monitor field devices such as limit switches, buttons, position sensors, and alarm contacts. When a channel changes state, it can trigger alarms, switch outputs, log events, or execute safety shutdowns. Its high channel density and reliability make it a standard digital input board for large-scale automation systems including process control, manufacturing, energy, and chemical plants.
