Physical Dimensions and Component Layout

This panel measures 18.0 cm in length and 12.0 cm in width. Its total depth reaches 3.5 cm including the mounting flange. 6ES5398-0DE12 weighs just 0.45 kg for panel mounting. You will find 42 discrete components on a two-layer PCB.

Moreover, the panel integrates a 100 µF capacitor for supply smoothing. This capacitor filters noise from the 24V DC power source. It also provides a brief hold-up during momentary voltage dips.

Display and Keypad Design

The LCD shows two lines with 16 characters per line. Backlighting allows easy reading in dim control rooms. Sixteen membrane keys provide data entry and function control. Each key features tactile feedback for confident operation.

Communication Interfaces

A 9-pin D-sub connector handles RS-232 communication to the CPU. A separate 15-pin D-sub port supports RS-422 for longer cable runs. An additional TTY current loop interface works with older S5 systems. LED indicators show power status and communication activity.

Typical Application Scenarios

You can deploy 6ES5398-0DE12 in SIMATIC S5-115U, 135U, and 155U systems. It also works well for standalone machine control panels. This panel displays production counts, alarm messages, and setpoints. Operators can acknowledge faults and adjust parameters using the keypad.
