Description

The Triconex Invensys DI3301 is a 32-point Digital Input Module designed for high-integrity industrial control and safety system applications. It provides 32 commoned 24 VDC input points with a 15–30 VDC operational range and fast signal acquisition for reliable monitoring of switches, sensors, contacts, and other discrete field devices. The module incorporates Force-to-Value Diagnostic (FVD) functionality, triplicated I/O bus architecture, and comprehensive channel status indication to support continuous diagnostics and dependable field signal processing. It is well suited for safety instrumented systems, emergency shutdown, process protection, fire and gas, and other critical industrial applications.

Features

Provides 32 digital input points in a single module for high-density monitoring of industrial field signals.
Designed for nominal 24 VDC inputs with a 15–30 VDC operational range for compatibility with common industrial discrete devices.
Triplicated I/O bus architecture supports high-integrity signal processing within compatible Triconex safety system configurations.
Force-to-Value Diagnostic (FVD) functionality provides active testing of input circuits to help identify potential faults.
Diagnostic tests are completed in less than 2 ms, supporting continuous fault detection with minimal impact on normal signal monitoring.
ADC scanning of all 32 input points is completed in less than 1 ms for rapid acquisition of field conditions.
Input response of less than 10 ms supports timely detection of changing process and safety signals.
Electrical isolation between functional circuits and protective or logic earth helps improve system protection and signal integrity.
PASS, FAULT, ACTIVE, and FIELD PWR indicators provide convenient module-level diagnostic information.
Individual indicators for all 32 input points simplify commissioning, troubleshooting, and maintenance of connected field circuits.
