Diagram of the Principle

This diagram illustrates the connection of the encoder supply:

Cable length:

Cable

Length

TSX CDP 053

0.5 m

TSX CDP 103

1 m

TSX CDP 203

2 m

TSX CDP 303

3 m

TSX CDP 503

5 m
NOTE: The maximum length of the wire between the supply outputs and the connection points on the TELEFAST should be less than 0.5 m.

Only one supply is required if the encoders on the two channels are of the same type.

Fuses

This module integrates several basic protection systems against wiring errors and accidental short circuits on the cable:

  • polarity inversions of the supplies,

  • inversion of 5 V supplies <--> 10/30 V,

  • 10/30 V short circuit on the CLOCK signal of the serial link.

The module cannot tolerate them for very long time, it should therefore have very fast blow fuses. The fuses should therefore be "rapid" and of 1A caliber maximum. Supplies should have a limitation current, such that the blow of the fuse can be correctly executed.
