The optional 4DI (LC) submodule enables an on-site control of the e-starter. This means that commands can be sent to the e-Starter via the four freely parameterizable inputs, regardless of the higher-level control, so that tests can be carried out with the connected motor during commissioning, for example. The ET 200SP distributed I/O system replaces the tried and tested ET 200S system. E-Starter ET 200SP - Flexible. High Performance. Reliable.This text is machine translated.
