T9191

The T9191 is a tall blanking cover for unused I/O slots in the AADvance T9100 6U chassis, specifically for positions without a terminal assembly (FTA) installedRockwell Automation. It fills empty module slots to maintain safety, mechanical integrity, EMI shielding, and airflow in the chassis. It is a passive, non‑electronic accessory (no logic, no I/O, no communications) used in system build, expansion, or maintenance to cover vacant slots and prevent accidental contact with live backplane components.

1. Introduction

The T9191 is a tall blanking cover for unused I/O slots in the AADvance T9100 6U chassis, specifically for positions without a terminal assembly (FTA) installedRockwell Automation. It fills empty module slots to maintain safety, mechanical integrity, EMI shielding, and airflow in the chassis.
It is a passive, non‑electronic accessory (no logic, no I/O, no communications) used in system build, expansion, or maintenance to cover vacant slots and prevent accidental contact with live backplane components.

  • Function: Tall blanking cover for empty T9100 I/O slots (no FTA)

  • Compatibility: AADvance T9100 6U chassis (all slots 1–12)

  • Material: High‑impact polycarbonate, UL 94 V‑0 flame retardant

  • Installation: Snap‑fit, tool‑free (hot‑swap compatible)

  • Color: Dark gray (matches T9xxx modules)

  • Safety: Prevents contact with live backplane; dust/DEbris protection

2. Product Overview

The T9191 is a single‑width, 6U tall plastic cover that installs in any vacant slot of the T9100 chassis where no I/O module and no FTA are presentRockwell Automation. Unlike standard short blanking covers, the T9191 is “tall” to fully cover the vertical opening when no terminal assembly is fitted.
Key features:

  • Tall profile: Full 6U height for slots without FTARockwell Automation

  • Snap‑fit mounting: Tool‑free insertion/removal; aligns with chassis guides

  • EMI shielding: Maintains chassis EMI integrity when slots are empty

  • Airflow management: Preserves designed cooling airflow across all slots

  • Safety compliance: Blocks access to live backplane connectors; meets IP20 for cabinet installations

  • Harsh environment: Robust polycarbonate withstands industrial temperature, vibration, and dust

Common applications:

  • T9100 chassis unused I/O slots (no FTA installed)

  • System build/configuration (before adding I/O modules)

  • Maintenance (temporary removal of I/O without FTA)

  • Spare slot coverage in ESD/BMS/SIL 3 systems
