Product Description:
The SOT02-E2A-CU station operator terminal is produced by Bosch Rexroth Indramat and belongs to the SOT Operator Panels series. It is a flush-mounted unit intended for machine-level control and diagnostics, allowing operators to issue commands and view status messages through its integrated display and keypad. Within an automated cell, the panel acts as the local interface that exchanges data with PLCs over serial links while its internal electronics are powered from a 24 VDC control circuit. This arrangement gives operators a direct way to navigate machine functions and respond to alarms without relying on a separate computer.
The interface uses a 16-line display to present menus, faults, and process variables, and that screen is sized at 4-7/8 × 2-3/4 in, giving clear text visibility from normal panel distances. User programs reside in 512 KB of battery-backed RAM, with retention provided by a 3.6 V lithium cell so parameter data persists during power loss. Control electronics operate from a nominal 24 VDC supply and draw only 110 mA, minimizing load on the cabinet power supply. For host communication, it offers a 50 ft RS-232 link for close-coupled devices and a half-duplex RS-485 channel for multidrop wiring. ScreenManager™ software is used to configure display pages and key assignments, which supports straightforward setup of text screens and key functions.
Field wiring terminals on the rear provide 8 × 24 VDC local outputs that can drive indicator lamps or interposing relays without additional interface modules. The front face carries an IP65 rating when properly gasketed against the enclosure, while the rear electronics compartment is protected to IP30. This arrangement lets the operator side face harsher shop conditions while the cabinet side remains suited to enclosed installation. RS-485 cabling may extend to 1000 m, enabling the panel to be positioned far from the central controller in distributed layouts. A standard membrane keyboard and the station construction type support routine operator input in production cells that need simple, text-based interaction.
