Product Overview

The T8270 is a 19-inch rack mount forced-air cooling tray designed exclusively for the ICS Triplex Trusted triple modular redundant safety system. It provides controlled airflow for T8100 processor chassis and T8300 expander chassis, preventing thermal overheating of safety-critical TMR modules during continuous operation. The unit uses four high-reliability brushless fans arranged in cross-wired redundant pairs, so a single electrical or fan failure will not fully interrupt cooling. Dual 24 VDC input paths and individual fuse protection enhance availability for SIL-rated safety instrumented systems. This tray is mandatory for hazardous area approvals of the Trusted platform and is widely sourced as a spare for petrochemical, oil & gas and power safety shutdown retrofits.
