The EL5152 EtherCAT Terminal is an interface for the direct connection of two incremental encoders (24-V-HTL) with A and B track. As an alternative, the EL5152 can be used as a up/down counter. The 24 V supply of the encoder can be provided directly via the terminal connection points.

Special features:

• parametrizable per channel
• function set counter via process data possible
• integrated frequency and period measurement
• optionally usable as 24 V up/down counter
• Microincrements
• synchronous reading of the position value via distributed clocks

In addition, the EL5152 enables the measurement of a period or frequency with a resolution of 100 ns. With the optional interpolating microincrement functionality, the EL5152 can provide even more accurate axis positions for dynamic axes. It also supports synchronous reading of the encoder value together with other input data in the EtherCAT system via the high-precision EtherCAT distributed clocks (DC). The use of encoder profiles enables simple and fast linking of the process data for Motion Control applications.
