It reads incremental encoders (symmetrical or asymmetrical) and absolute SSI encoders, and outputs cam signals based on programmed cam tracks. The encoder input frequency tops out at 50 kHz with a 25 m cable, dropping to 25 kHz at the full 100 m cable length — so if your application runs a high-speed encoder at the far end of a long cable, budget the lower frequency limit. ## Digital I/O and signal levels The module provides 4 digital inputs and 13 digital outputs. Inputs accept 24 VDC nominal, with a Signal \"1\" threshold of +11 to +30 V and a Signal \"0\" range of -3 to +5 V. The differential encoder inputs (DATA, notDATA; CL, notCL) expect RS-422 levels, with Signal \"1\" minimum at UP - 0.8 V and a typical current draw of 9 mA per channel. The 13 digital outputs are rated for a maximum of 300 mA total, with short-circuit protection built in.","metaTitle":"Siemens 6ES7352-1AH01-0AE0 FM 352, 50 kHz Encoder Input, EOL","metaDescription":"Siemens 6ES7352-1AH01-0AE0 FM 352 cam controller module. 50 kHz encoder input, 4 DI / 13 DO, SSI & incremental.
