The T8270 is a 24V DC rack fan assembly from ICS Triplex‘s Trusted series, engineered to provide forced-air cooling for Trusted TMR system chassis including T8100, T8200, and T8300 racks. The T8270 integrates four Papst 8414NG industrial DC fans delivering 69 m³/h each, powered by dual redundant 24V DC inputs with internal 250 mA fusing per fan group. With 2U 19″ rack form factor, hot-swap capability, and comprehensive diagnostics (per-fan speed monitoring, fault LEDs, and stall/undervoltage/overcurrent alerts to the TMR controller), the T8270 ensures reliable thermal management for SIL 3 safety applications.
Forced-Air Cooling – Provides active airflow to dissipate heat from processor, I/O, and communication modules within Trusted system racks
Redundant Thermal Management – Dual 24V DC power inputs and four fans in cross-group pairs ensure continued cooling even with one power source or single fan failure
Fault Detection & Reporting – Per-fan speed monitoring with independent fault LEDs; stall, undervoltage, and overcurrent conditions reported to TMR controller via SOE alarms
System Integration – Powered by Trusted Power Distribution Unit (T8292) via dedicated fan power cable (TC-011-01)
Hot-Swap Replacement – Supports online module replacement without system shutdown or safety system interruption
High Airflow Capacity – 69 m³/h (40.6 ft³/min) per fan @ 3100 rpm for effective chassis cooling
Redundant Power Inputs – Dual 24V DC feeds (18–28V range) ensure continued operation if one supply fails
Redundant Fan Configuration – Four fans arranged in two cross-coupled groups; single fan failure does not compromise whole-group cooling
Comprehensive Protection – Internal 250 mA anti-surge fuses per fan group; reverse polarity, overload, and short-circuit hardware protection
Long Service Life – 70,000 hours MTBF @ 40°C; 35,000 hours @ 70°C
Low Noise Operation – <32 dB(A) per fan for quiet control room environments
Hot-Swap Capable – Standard rack plug-in structure; online replacement without system downtime
Integrated Airflow Management – Built-in baffle prevents air from flowing directly through the module chassis immediately above the fan tray, ensuring targeted cooling
Rugged Industrial Design – Metal housing with IP20 protection; resistant to oil mist, dust, and variable-frequency strong electromagnetic interference
The T8270 functions as the primary active cooling component within the Trusted TMR system chassis architecture. Installed in a standard 2U 19″ rack slot, the module draws power from the Trusted Power Distribution Unit (T8292) via a dedicated fan power cable (TC-011-01).
The four Papst 8414NG DC fans are vertically mounted within the chassis and operate at up to 3100 rpm, delivering 69 m³/h of airflow each. The integrated baffle prevents air from flowing directly through the module chassis immediately above the fan tray, instead directing airflow to dissipate heat from critical processor, I/O, and communication modules.
Power is supplied via dual redundant 24V DC inputs (18–28V range). The four fans are arranged in two cross-coupled groups, each with an independent 250 mA anti-surge fuse. This redundancy ensures that a single power source failure or single fan failure does not result in total cooling loss—the remaining fans continue to maintain adequate airflow.
Each fan has independent speed monitoring with panel fault LEDs. Stall, undervoltage, or overcurrent conditions are reported to the TMR controller via Sequence of Events (SOE) alarms. The module supports hot-swap replacement, allowing online replacement without system shutdown. The exhaust air is typically drawn upwards and out of the system cabinet by roof-mounted fans (e.g., T8271), forming a complete cooling solution.
Q1: What is the primary function of the T8270?
A1: The T8270 is a 24V DC rack fan assembly that provides forced-air cooling for Trusted TMR system chassis, ensuring critical processor, I/O, and communication modules operate within their specified thermal limits.
Q2: Which system racks is the T8270 compatible with?
A2: The T8270 is designed for T8100 (main controller rack), T8200 (power rack), and T8300 (expansion I/O rack) Trusted system chassis.
Q3: What is the airflow capacity of the T8270?
A3: Each of the four Papst 8414NG fans delivers 69 m³/h (40.6 ft³/min) at 3100 rpm.
Q4: Does the T8270 support redundant operation?
A4: Yes. The T8270 features dual 24V DC redundant power inputs and four fans in two cross-coupled groups. A single power source failure or single fan failure does not result in total cooling loss; the remaining fans continue to operate.
Q5: Can the T8270 be replaced without shutting down the system?
A5: Yes. The T8270 supports hot-swap replacement—it can be removed and replaced online without system shutdown or interrupting safety system operation.
