System role

This section explains what the product does and where it acts in the surrounding system.

Function: Receives absolute position data from one SSI encoder channel for the PLC.
System position: Sits between the SSI absolute encoder and the PLC position-processing application.
Upstream / inputs: Receives the SSI serial position signal from the connected absolute encoder.
Downstream / outputs: Transmits the encoder position value to the PLC application.
Limitations: Unknown: encoder resolution, electrical wiring, current availability, and installation-specific compatibility are not established by the cited page.
