ICS Triplex T8270 Trusted Fan Tray | Seven Star LLC
Overview
The ICS Triplex Trusted T8270 fan tray is the Trusted 24 V dc fan assembly, rack mounted, part of the cooling system of the Trusted safety and control platform manufactured by ICS Triplex, now Rockwell Automation. The original listing identifies it as the ICS Triplex T8270 24 V dc fan assembly, rack mount, and the official Rockwell documentation confirms the product description as the Trusted 24 Vdc Fan Assembly, Rack Mounted.
The T8270 fan tray provides forced cooling within a module rack of a Trusted system, with one fan tray fitted per module chassis, so that the safety and control modules inside the rack operate within their temperature limits. A fully populated module rack includes up to five fan trays and may also include a roof fan unit.
Engineering & Design
The T8270 fan tray comprises four fans mounted vertically at the rear of a 2U high chassis, with a baffle that directs the air drawn by the fans across the module chassis above the tray. Each fan is a Papst 8414NG unit capable of moving 69 m³/h at a nominal rotor speed of 3100 rpm, with electronic overload and reverse polarity protection, and the tray is designed for low noise operation at 32 dB per fan.
The T8270 fan tray is powered from dual 24 V dc supplies, with the fans supplied in pairs through internal 250 mA anti-surge fuses, and the supply range is 18 to 28 V dc. Power is derived from a Trusted Power Distribution Unit miniature circuit breaker (24 V dc, type T8292) through a Trusted fan power cable, type TC-011-01. The fan MTBF is 70,000 hours at 40 °C.
