Encoder interface module for ET 200SP
The 6ES7138-4DL00-0AB0: This ET 200SP module captures encoder feedback from both incremental encoders via differential RS-422 inputs and absolute SSI encoders. The 500 kHz maximum input frequency covers typical servo and stepper feedback rates, and the 64 µs monoflop time filters zero‑mark bounce. Output current up to 500 mA is available for encoder supply or a small load; rated for 24 V DC supply, with reverse polarity protection and short‑circuit protection on the output. Power loss is typically 2 W.
