Product Description:
The SOT02-E1A-CA is a station operator terminal developed by Bosch Rexroth Indramat for the SOT Operator Panels series. Serving as a compact human-machine interface, the unit presents process variables, alarms, and diagnostic text to local operators and accepts keypad entries that travel directly to programmable logic or motion controllers for routine machine interaction. Its compact format suits stations where operators need immediate visual feedback and simple data entry without giving up space for a larger display assembly. A standard application designation and station-unit construction support fixed installation on machinery frames, making the panel a direct link between shop-floor equipment and higher-level automation software.
At the front, a 16-line display presents alphanumeric data across a viewing area measuring 4-7/8 × 2-3/4 in. This size allows several process variables and menu items to be shown simultaneously without scrolling, which helps reduce unnecessary screen changes during normal operation. Illumination is supplied by a cold cathode fluorescent backlight so the text remains legible in dimly lit production zones. The panel carries 128 KB of onboard RAM to store pages, message buffers, and user variables, and it communicates with controllers at rates up to 19200 baud through its serial port. A standard keyboard layout and a non-glare screen finish further aid continuous operator interaction, while an MS-DOS-based ScreenManager host operating system handles configuration files.
For field networking, the terminal can share a single link with as many as 15 units, each addressed individually in the SOT chain. Downstream cabling options include an RS-232 segment that may extend to 15 m for point-to-point connections, and an RS-485 segment that can run up to 1000 m for multidrop layouts across larger plants. Display legibility can be tuned on site because the contrast is user-adjustable, helping operators adapt the panel to changing lighting or mounting angles without tools. Separate serial distances let the same terminal fit short cabinet runs as well as longer plant-floor networks.
