Main Features
Features:
- Simple installation and connection
- Capable of moving 69 m3/h (40.6 ft3/min)
- Trusted 24 Vdc Fan Assembly Rack Mounted
The Trusted Fan Tray 24 Vdc Rack Mounted comprises four fans mounted vertically at the rear of a 2U high chassis. The chassis containing the fans incorporates a baffle to prevent air drawn by the fans flowing through the module chassis immediately above the Fan Tray. Air exhausted by the fans into the rear of the system cabinet is drawn upwards and out of the cabinet by roof-mounted fans.
The Fan Tray is powered from dual 24 Vdc supplies arranged such that the fans are supplied in pairs via 250 mA anti-surge fuses. The 0 V supply is connected via terminal block TB1. Each fan is capable of moving 69 m3/h when operating with a nominal rotor speed of 3100 rpm. Protection against overloading and reverse polarity is provided electronically for each fan.
The T8270 ICS Triplex Fan Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

According to Rockwell Automation's safety compliance documentation, application layouts must adhere to the following stringent guidelines:
Quantity Baseline: Standard systems engineering requires one T8270 component per active module chassis within each rack unit.
Power Distribution Restrictions: Power must be supplied via a dedicated, reliable power distribution unit (e.g., a T8292 24 Vdc miniature circuit breaker module). A single T8292 circuit breaker circuit can support up to five T8270 fan mounts and one top exhaust unit.
Empty Slot Rule: Empty slots affect calculated airflow pressure. Any unused T8270 space in the rack must be physically sealed using a standard single-width T8191 or triple-width T8193 baffle to force cool airflow through the active processor.
The main supply for the Fan Tray is derived from a Trusted Power Distribution Unit MCB 24 Vdc - T8292 via a Trusted Fan Power Cable – TC-011-01. The same type of cable is used to interconnect the Fan Trays/Roof Fans in a Trusted System module rack. A fully populated module rack will include five Fan Trays, and may also include a Roof Fan Unit. This is the maximum number of Fan Trays/Roof Fan Units that may be powered from a single Trusted Power Distribution Unit miniature circuit breaker (MCB).
