Description

The 3502E is a high-reliability digital input (DI) module designed for safety-critical applications. It features triple-modular redundancy (TMR) with self-test capabilities to ensure maximum availability and safety. The module has three isolated input channels that independently process all data, ensuring the highest integrity of input signals. Each channel conditions signals independently and provides optical isolation between the field and the Tricon system.

Features

Triple-Modular Redundancy (TMR): Ensures operation in the presence of single faults.
Self-Test Capability: Detects stuck-ON conditions, critical for de-energize-to-trip safety systems.
Voltage Options: 48 VAC/VDC
Commoned Points: 32 points, commoned in groups of 8.
Enhanced Diagnostics: Continuous self-tests and fault detection.
Hot-Spare Support: Ensures continuous operation during failures.
Mechanical Keying: Prevents improper installation.
Diagnostic Indicators: PASS, FAULT, ACTIVE status per point.
