Product Description

Product Overview

The T8472 from ICS Triplex (Honeywell Trusted® systems) is a 120VAC Digital Output Module designed for high-reliability, fault-tolerant control in critical industrial systems. It features Triple Modular Redundancy (TMR) architecture to ensure continuous operation and system safety in demanding environments.

Functional Description

T8472 delivers:

16 AC digital output channels, divided into 2 independent power groups
Each channel supports up to 0.5 A; each group up to 4 A continuous, 8 A peak surge
Output voltage range: 90–150 VAC, 47–63 Hz
Optical isolation rated up to 2500 V for noise immunity and EMI/RFI protection
Built-in diagnostics with self-test, open/short detection, and Sequence of Events (SOE) logging
Hot-swappable design allows replacement without system downtime
Triple Modular Redundancy (TMR) for maximum fault tolerance and SIL 3 compliance
