Description
Product Introduction
ICS TRIPLEX T8270 is the 24 V DC forced-air fan tray for Rockwell’s Trusted TMR safety system, designed to exhaust heat from processor and power modules in 19-inch racks.literature.rockwellautomation+1
This 2U assembly mounts at the rack rear, uses four Papst 8414NG fans to deliver ~276 m³/h total airflow, and is powered via dual redundant 24 V DC feeds from a T8292 power distribution unit.literature.rockwellautomation+1
Frequently Asked Questions
Q: Can I hot-swap the T8270 fan assembly?
A: No. The T8270 is a cooling accessory, not a redundant I/O module. You must power down the rack or isolate the 24 V DC feed before removing the fan tray to avoid shorting the TC-011-02 connector and to protect personnel from moving fans.literature.rockwellautomation+1
Q: Is the T8270 obsolete? Are there direct replacements?
A: Yes, the T8270 is effectively obsolete in new production. The direct replacement is the same T8270 assembly (still available as surplus) or individual Papst 8414NG fans if you rebuild the tray. For newer Trusted racks, Rockwell offers updated fan trays, but verify mechanical envelope and connector type.controltech-supply+1
Q: Will I lose my control program when replacing the fan assembly?
A: No. The T8270 provides cooling only; it has no logic or configuration memory. Control programs reside in the TMR processors (e.g., T8110B). However, always back up the Trusted project before any hardware intervention.konmask+1
Q: Are these units factory-new or refurbished?
A: Most available stock is New Surplus (original packaging, never installed) or tested used units with 12-month warranty. Genuine Rockwell/ICS Triplex factory-new T8270 trays are rare. Request photos of packaging and serial labels for audit.ebay+1
Q: What warranty and lead time should I expect?
A: Surplus suppliers typically offer 12 months warranty on tested units; New Surplus may have 6–12 months. Lead times: in-stock units ship in 1–3 days, but export paperwork and customs can add 5–8 working days.
