Principles for connecting an encoder to a TSX CCY 1128
Connection interfaces
Illustration
The 15-pin SUB D connector, located on the front panel of the module, allows the connection of encoder and module. This connector carries: l l all signals travelling to or from the encoder, the encoder supply source, which is also connected: l either by a TELEFAST ABE-7H16R20 cable interface. l or directly, using a TSX CDP •01 prewired strand
The design of the module allows the encoder to be connected at either 5VDC or
10…30VDC.
The diagram below shows the principles for connecting an encoder to a TSX CCY
1128 module.

When connecting, adhere to the following recommendations:
Connect each signal encoder A+/A-, B+/B-, Z+/Z-, using a twisted pair.
l
Connect each supply point using a twisted pair, in order to reduce the on-line voltage falls.

Recommendations l l l
Maximum length of wires between the supply outputs and the connection points on the TELEFAST: must be less than 0.5 meters.
Protection on the + supply: although the module has several built-in protection systems to guard against wiring errors and accidental short-circuits on the cables, it is vital to install a 1A maximum non-delay fuse (Fu) on the + supply.
Connection of the 0 V supply to the protective ground: must be as close as possible to the supply output.
