The EL5101 is an EtherCAT Terminal designed for precise position measurement and motion control applications. Here's a summary of its features:

• Interface Type: Incremental encoder interface supporting differential signals (RS422) and single-ended signals (TTL).

• Input Frequency: Capable of evaluating frequencies up to 1 MHz.

• Additional Inputs: Includes two 24 V digital inputs for storing, blocking, and setting counter status.

• Encoder Supply: Provides 5 V and 24 V supply directly via terminal connection points.

• Measurement Capabilities: Supports period and frequency measurement with a resolution of 100 ns.

• Microincrements: Offers interpolating microincrement functionality for enhanced axis position accuracy.

• Distributed Clocks: Enables synchronous reading of encoder values and other input data with high precision.

• Timestamping: Includes a timestamp for the last-registered incremental edge.

• Counter: Features a 16/32-bit switchable counter.
