Beckhoff EL5151-0090 | EtherCAT Terminal, 1-channel encoder interface, incremental

The EL5151-0090 EtherCAT Terminal is an interface for the direct connection

of one incremental encoder (24 V HTL). An additional 24 V digital input is

available for storing or blockingthe counter status. As an alternative, the

EL5151-0090 can be used as a up/down counter.

The 24 V supply of the encoder can be provided directly via the terminal

connection points.

The EL5151-0090 also supports TwinSAFE SC (TwinSAFE Single Channel).

This enables standard signals to be used for safety-related tasks in any

network or fieldbus.

Special features:

• supports the TwinSAFE SC technology

• save, lock, set counter

• integrated frequency and period measurement

• optional 24 V up/down counter

• microincrements

• synchronous reading of the position value via distributed clocks

• timestamp on the last-registered incremental edge

In addition, the EL5151-0090 enables the measurement of a period or frequency

with a resolution of 100 ns. With the optional interpolating microincrement

functionality, the EL5151-0090 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). A timestamp for the last-registered incremental edge is also

available. The use of encoder profiles enables simple and fast linking of the process

data for motion control applications.
