EL5112 - Introduction

Two-channel incremental encoder interface terminal 5 V (2xAB or 1xABC RS422, TTL)

The EL5112 EtherCAT Terminal is an interface for the direct connection of two incremental encoders with A and B tracks or one encoder with A, B and C tracks. Encoders with differential signals (RS422) or single-ended signals (TTL and Open Collector) can be connected and supplied with power directly from the terminal.

In 2-channel mode, both channels of the gate can be used for locking the counter and optionally as a latch for the separate storage of the counter value. Up to two latch inputs are available in single-channel mode.

The EL5112 enables the measurement of period, frequency and speed with a resolution of 10 ns. In addition, duty cycle measurement of the incoming signal is implemented.

Due to the optional interpolating micro-increment function, the EL5112 can supply even more precise axis positions for dynamic axes. In addition to that it supports the synchronous reading of the encoder value together with other input data in the EtherCAT system via high-precision EtherCAT Distributed Clocks (DC). In addition, timestamps can be output for the last registered incremental edge, the edge at the latch input and the zero pulse track C.
