About us
Introduction
To ensure position measurement, the TSX CAY modules are equipped with connectors allowing direct connection of an incremental or absolute SSI encoder on each channel. Each of these channels can be equipped with a different type of encoder.
Signal Labeling
TSX CAY modules can be connected either to incremental encoders, or to SSI type encoders with serial links. In configuration mode, the available functions are as follows:
A 15-pin SUB-D connector is assigned to each channel. This also allows the encoder supply. These supplies are elaborated from the +supply discrete HE10 connector. Signal: +return supply encoder, from the encoder allows monitoring for accidental disconnection of the encoder.
