The ICS Triplex T8151B is a Trusted Communications Interface (CI) module designed for high-integrity, fault-tolerant TMR (Triple Modular Redundant) systems. It facilitates communication between Trusted controllers and external systems via dual Ethernet (10/100BaseT) and four configurable serial ports, using 2-out-of-3 voting for data consistency.

The T8151B ICS Triplex Trusted Communications Interface (CI) module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).
ICS Triplex T8151B Trusted Communications Interface (CI) module Manuals, Datasheets, Drivers, Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The ICS Triplex T8151B Trusted Communications Interface (CI) is a high-performance, fault-tolerant module for TMR Trusted Controllers. It manages communication loads, supporting dual Ethernet and four serial ports (RS-232/422/485). It facilitates Modbus, Trusted Peer-to-Peer, and Sequence of Events (SOE) logging, operating at 20–32 Vdc.
Triple Modular Redundancy (TMR) Integrity: The module uses a triplicated Inter-Module Bus (IMB) with 2-out-of-3 (2oo3) voting. This ensures that even if one internal path fails, the data remains consistent and the system stays online.
 
Redundant Power Supply: The T8151B operates on dual redundant +24 Vdc power feeds from the chassis backplane. An on-board Power Supply Unit (PSU) provides supply conditioning and protection against voltage fluctuations (supporting 20–32 Vdc).
 
Sequence of Events (SOE) Logging: The module includes an optional SOE buffer that logs up to 4,000 timestamped events. This is critical for forensic analysis and "fault tracing" in safety-critical applications.
