• 750-630 (/xxx-xxx) [SSI Transmitter Interface] Description 2.1.1.3 Description This module is an SSI interface for the direct connection to an SSI transmitter. The power supply for the transmitter is derived internally from the power jumper contacts. After the interface has given a clock pulse to the sensor, the interface reads the incoming data and transmits it directly in the form of a data word into the process image of the PLC or PC.
