Siemens SIMATIC S7-1500 Counter + position detection module Part number 6ES7551-1AB00-0AB0

Spare part

SIMATIC S7-1500, TM PosInput 2 counter and position detection module for RS-422 incremental encoder or SSI absolute encoder, 2 channels, 2 DI, 2 DQ per channel SIMATIC ET 200MP is a modular and scalable I/O system with IP20 for universal use, and offers the same system advantages as the S7-1500. It permits the shortest bus cycle times and fastest response times, even with large volumes of data. The distributed I/O system is particularly easy to install, wire, and commission. Thanks to its scalable design, you can gear the IO station exactly to the on-site requirements.

Technology modules provide hardware-related signal preprocessing for high-speed counting, exactmeasuring, position detection and pulse width modulation for various encoders and actuators and the control of stepper motor drives and servo drives via PTI interface.
