3A98871H01
Part Number: 3A98871H01 is original Westinghouse / Emerson 101-key industrial engineering keyboard, OEM produced by NMB with model RT101 and auxiliary part code 116305-002. It is a dedicated HMI input device exclusively configured for SPARC-based WEStation workstations under legacy WDPF DCS system, widely deployed at central control room of thermal power and nuclear power plants. The suffix H denotes black casing and matched original black shielded connecting cable, which differentiates it from green-cable operator keyboard series such as 3A98963G. Original factory mass production has been permanently discontinued; available market products include fully power-on inspected refurbished keyboards and genuine dismantled original spare units for DCS overhaul and fault replacement.

1. Product Overview
Part Number: 3A98871H01 is original Westinghouse / Emerson 101-key industrial engineering keyboard, OEM produced by NMB with model RT101 and auxiliary part code 116305-002. It is a dedicated HMI input device exclusively configured for SPARC-based WEStation workstations under legacy WDPF DCS system, widely deployed at central control room of thermal power and nuclear power plants. The suffix H denotes black casing and matched original black shielded connecting cable, which differentiates it from green-cable operator keyboard series such as 3A98963G. Original factory mass production has been permanently discontinued; available market products include fully power-on inspected refurbished keyboards and genuine dismantled original spare units for DCS overhaul and fault replacement.
2. Mechanical and Interface Specifications
Adopts standard ANSI 101-key full-size industrial layout with dustproof, high-temperature resistant and wear-resistant keycaps. Custom shortcut function keys are pre-defined to match WDPF system operation including screen switching, DPU logic download and alarm acknowledgment. The main communication port is proprietary SUN Mini-DIN 5-pin round connector, designed to connect with 3A98833H series black SCSI signal cables to the backplane of VME main chassis; certain batches reserve an extra auxiliary DB9 serial port at rear panel. Short fixed-length black shielded cable is pre-assembled at factory for direct workstation wiring.
3. Electrical & Environmental Specifications
Operating power supply is DC5V fed from WEStation internal backplane power circuit. Internal circuit layout is wrapped with full aluminum foil shielding to restrain electromagnetic interference generated by cabinet inverters, contactors and power modules. Continuous operating ambient temperature ranges from 0℃ to +55℃ inside control room; spare storage temperature spans from -40℃ to +85℃, applicable relative humidity between 5% and 95% under non-condensing condition, conforming to CE industrial control component standards.
4. Core Application Functions
Serves as primary input equipment for WDPF engineer stations to complete system configuration, parameter modification, graphic access and offline logic programming. Normally used as complete console set cooperating with 3A98826 series panel trackball and matched 3A98833H connecting cables for routine monitoring and operational command input. It is the preferred replacement spare during aged unit DCS renovation, control desk upgrade and on-site keyboard breakdown maintenance.
5. Supply & Delivery Information
Brand new factory-original inventory is extremely scarce globally. In-stock goods consist of warranty-attached refurbished keyboards and pre-tested used original spares. Standard delivery lead time is two to four working weeks; expedited urgent shipment can be arranged for emergency site maintenance demand. Global delivery is supported via DHL, UPS and FedEx international courier, and professional repair service for defective keyboards is available upon request.
