ABB Bailey INFI90 MCS Keyboard Interface Assembly (6637517A1 / 660-MISC-3311)

Product Description

The ABB Bailey 6637517A1 (also referenced as 660-MISC-3311) is an industrial-grade keyboard interface assembly designed exclusively for the INFI90/Network90 MCS (Man-Machine Station) operator consoles. As a critical component of legacy DCS (Distributed Control System) operator interfaces, this rack-mount module bridges the physical keyboard to the MCS processor, enabling reliable input signal translation, key debouncing, and communication protocol conversion for the INFI90 system bus. It features dedicated keyboard ports (compatible with Bailey 210-key industrial operator keyboards), robust EMI/RFI shielding, industrial temperature tolerance, and compliance with INFI90 system electrical specifications—ideal for retrofitting, upgrading, or repairing operator stations in power generation, oil & gas, chemical processing, and water/wastewater treatment facilities.

Key Functions

The 6637517A1/660-MISC-3311 keyboard interface delivers mission-critical operator input processing with these core features: Dedicated connection for Bailey 210-key industrial operator keyboards (compatible with legacy Bailey keyboard models); Signal translation & debouncing to eliminate key chatter and ensure accurate input to the MCS processor; Protocol conversion between the keyboard’s physical layer and the INFI90 system bus; Robust EMI/RFI shielding to withstand harsh industrial electrical noise; Industrial temperature operation (-20°C to +60°C) for reliable performance in control room and field environments; Plug-and-play compatibility with INFI90 MCS consoles, minimizing downtime during replacement/upgrade.

Application Scenarios

The Bailey MCS keyboard interface is designed for legacy DCS operator station applications including: Retrofit/replacement of faulty keyboard interface modules in INFI90/Network90 MCS consoles; Upgrades to industrial operator stations to support newer Bailey-compatible keyboards; Repair of control room operator interfaces in power plants, oil refineries, and chemical processing facilities; System expansion projects requiring additional MCS operator stations with reliable keyboard input processing; Compliance-driven upgrades to maintain operational continuity of legacy DCS systems in regulated industries.
