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.","metaTitle":"Siemens 6ES7138-4DL00-0AB0 ET 200SP Pos Input 500 kHz","metaDescription":"Siemens 6ES7138-4DL00-0AB0 ET 200SP position encoder input module.
