985210201 X-DI 32 Digital Input Module

Product Brief Description

985210201 X-DI 32 is a high-density 32-channel digital input module for industrial distributed control and safety systems. It is designed to collect discrete on-off signals from field sensors, limit switches, proximity switches and relay contacts. It supports common industrial DC input voltage levels, features channel isolation, short-circuit protection and diagnostic functions, and transmits digital status information to the backplane bus controller. It is widely deployed in factory automation, power and process control systems for spare replacement and system expansion.

Product Functions

• 32-channel digital input for reading discrete contact and switch status signals
• Individual channel isolation to reduce crosstalk and improve anti-interference performance
• Built-in channel diagnostic function for open circuit and short circuit fault detection
• Support standard 24VDC field input signal, compatible with most field sensors
• Transmit collected digital status data to the host controller via internal backplane bus
• Overcurrent and reverse polarity protection for each input channel
• LED status indicators for each channel to simplify on-site commissioning and troubleshooting
• Compact rack-mounted design, suitable for standard industrial control cabinet installation

Application Scenarios

• Power plant DCS and auxiliary equipment interlock control systems
• Petrochemical, chemical and water treatment process automation
• Packaging, material handling and general factory automation production lines
• Conveyor, fan, pump and valve discrete status monitoring
• Industrial control system expansion, upgrade and spare parts stocking
• Building HVAC and machinery safety interlock monitoring
