Description
Product Description
The ICS Triplex T8403 is a 40-channel digital input module designed for the Trusted Triple Modular Redundant (TMR) control system. It monitors 24 V DC field signals from devices such as switches, sensors, and status contacts, supporting high-integrity monitoring in safety-critical industrial applications.
The T8403 provides triple-modular-redundant signal processing, built-in diagnostics, and Sequence of Events (SOE) reporting with 1 ms resolution. It supports configurable field line monitoring and online replacement when the system rack configuration and maintenance procedures permit. Typical applications include emergency shutdown (ESD), fire and gas protection, and safety instrumented systems. Confirm system compatibility, terminal arrangements, and configuration requirements before installation.
