3. Product Overview

The 51401437-301 is a dedicated industrial operator keyboard for Honeywell TDC3000 and TPS GUS operator stations. It is not a standard PC keyboard, with custom function keys optimized for DCS daily operation, including alarm confirmation, graphic page switching, trend viewing and setpoint adjustment. The membrane key structure is dust-resistant and wear-resistant to support 24/7 continuous operation in central control rooms. The integrated backlight and status LEDs help operators quickly identify communication status and system alarms. The proprietary communication interface directly connects to the GUS station. It is an obsolete spare part for maintenance replacement of legacy DCS systems in oil & gas, chemical, power and petrochemical plants.
