8200-1301 | Woodward 505D Series | Graphical Operator HMI Panel

Product Description

The 8200-1301 is a panel-mounted graphical operator interface engineered for use with the Woodward 505D Digital Governor. Designed as the primary human–machine interface, this unit combines display, keypad, and power-input circuitry into a single, industrial-grade front panel.

As part of the Woodward 505D ecosystem, the 8200-1301 enables direct local interaction with steam-turbine control logic, providing clear visualization of operating conditions, alarm states, and control commands. Its wide-range AC/DC power acceptance allows flexible installation across diverse turbine control panels without additional power conversion hardware.

This model represents the standard AC/DC variant within the 8200 HMI family and is commonly deployed in non-hazardous industrial environments.

Key Technical Characteristics

Power Supply and Electrical Design

• Rated input voltage:
  • 88–132 Vac, 50/60 Hz
  • 90–150 Vdc
• Dual-range AC/DC input with automatic selection
• Maximum power draw below 73 W
• Peak input current up to 1.6 A under AC operation
• Overvoltage Category III when installed in accordance with system guidelines

Mechanical and Environmental Attributes

• Panel-mount construction for control cabinets
• Front-panel enclosure classification IP20
• Intended for indoor industrial control rooms
• Thermal design aligned with turbine-control environments; compatible with temperature ranges typical of 505D installations

Interface and Functional Capabilities

• Integrated graphical display with tactile keypad
• Local execution of turbine start and shutdown sequences
• Operator adjustment of speed, load, and control setpoints
• Alarm display, acknowledgment, and event review
• Diagnostic access via the connected 505D controller
• Communication handled through the governor’s Modbus interface

System Integration Role

Within a 505D-based turbine control system, the 8200-1301 serves as the operator’s primary point of interaction. It does not perform control logic independently; instead, it presents real-time data from the governor, transmits operator commands, and supports commissioning and troubleshooting activities described in Woodward 505D documentation.

Application Scenarios

• Industrial steam-turbine generator sets
• Mechanical-drive steam turbines
• Process plants requiring local governor operation
• Power-generation facilities using Woodward 505D governors

Frequently Asked Questions

Q: Can the 8200-1301 be powered from either AC or DC without modification?
A: Yes. The unit supports both AC and DC inputs within the specified voltage ranges and automatically adapts to the supply type.

Q: Does this HMI replace the 505D controller?
A: No. The 8200-1301 is strictly an operator interface. Control logic and turbine regulation remain in the 505D governor.

Q: Is this model suitable for hazardous locations?
A: No. Hazardous-area installations require the 8200-1302 variant with appropriate certifications.
