ICS Triplex T8235 Trusted Series Module

The ICS Triplex T8235, also cataloged as the T8235 Module, operates as a dedicated hardware component for discrete signal processing and network telemetry within Trusted TMR architecture.

Hardware Specifications

Triple Modular Redundancy (TMR) & Galvanic Isolation

Engineered for SIL3 certification compliance under IEC 61508, the unit incorporates a triple modular redundancy (TMR) 2oo3 architecture across its main processor interface channels to eliminate single points of failure. High-density galvanic isolation rated at 2500 VAC prevents transient voltage surges from propagating across the internal backplane bus. Inter-channel fault detection logic guarantees immediate fail-safe state execution in the event of hardware degradation or field-side short circuits.

Frequently Asked Questions

Q: What is the maximum network switchover latency during a dual Ethernet interface failure?

A: The module executes hot-standby port failover within < 50 ms upon detecting physical layer link drop or signal loss on the active RJ45 port.

Q: Can the 32-channel digital input configuration handle field contact sensing without external pull-up resistors?

A: Yes, the 32 channel inputs support direct dry contact connections as well as active NPN/PNP field device configurations operating at standard 24 VDC levels.

Field Installation Guidelines

Mounting must be performed inside a sealed enclosure meeting minimum IP54 standards when deploying in unconditioned industrial spaces. Grounding leads must connect directly to the main cabinet earth rail using low-impedance braided copper straps with less than 1 Ohm resistance to ensure proper galvanic isolation performance. Maintain a minimum clearance of 50 mm above and below the module chassis to facilitate convection cooling. Field wiring cables must be segregated from high-voltage power lines by at least 200 mm to prevent electromagnetic interference on signal channels.
