Technical Specifications and Panel Design

This display panel with keypad provides operator interface for GE turbine control systems. The GE 336A3397P1 88JB2 allows local monitoring and command entry for Mark V controllers. You can mount this unit onto a control cabinet door or operator console. Its rugged front face withstands washdowns and industrial dust exposure. The panel weighs approximately 1.4 kilograms. Its dimensions measure 18 cm in height, 24 cm in width, and 7 cm in depth.

Display Features and Visual Indicators

The monochrome LCD presents text and basic graphics clearly. An LED backlight provides uniform illumination for low-light environments. The GE 336A3397P1 88JB2 displays up to 8 lines of 40 characters each. You can create custom screens for turbine start-up and shutdown sequences. The display contrast adjusts automatically based on ambient temperature. A green LED indicates proper power and communication status. The screen updates within 100 milliseconds of receiving new data.

Keypad Layout and Operator Controls

Twenty-eight membrane keys provide full operator control functionality. The keypad includes dedicated numeric keys for data entry tasks. The GE 336A3397P1 88JB2 features four soft keys for programmable functions. An emergency stop key provides immediate shutdown capability when pressed. Each key delivers tactile click feedback for confident operation. The spill-resistant design protects against accidental liquid splashes. Key presses register within 50 milliseconds of activation.

Communication and System Integration

You connect this panel to a Mark V controller through any serial port. The unit supports RS-232, RS-422, and RS-485 physical interfaces. A 9-pin D-sub connector provides the primary programming and runtime connection. The GE 336A3397P1 88JB2 draws operating power from an external 24V DC supply. It requires no internal battery for configuration or data retention. Therefore, all screen settings reside in the host controller memory. The panel acts purely as a display and input device.

Installation and Environmental Guidelines

You must cut a mounting hole measuring 160 mm by 220 mm in the cabinet door. The panel seals against the door with an included foam rubber gasket. The front face carries an IP65 rating for dust and water protection. Consequently, you can clean the panel with a damp cloth safely. The operating temperature ranges from 0°C to 50°C for reliable performance. You should avoid exposing the panel to direct sunlight for extended periods. The LED backlight has an average lifespan of 100,000 operating hours.
