TC-SPLIT
One product, multiple features:
•Signal converter: adapt encoder output voltage levels to devices inputs
(PLC, variable frequency drive …)
•Unipolar / differential converter
•Splitter: send encoder signals to multiples devices (4 outputs per
module, unlimited numbers of chained devices)
•Insulator: galvanic isolation between encoder and module outputs, and
between module outputs themselves.
•Multiplexer: Choice of the source encoder signal (using two chained
modules at least)

1 –Overview
TC-SPLIT Module allows connection of 4 devices on the same incremental encoder (or similar
devices). It can be chained in order to obtain 8,12,16 outputs.
3 independent channels (A,B,Z) are available on each device output
Encoder input signals can be configured as RS422/TTL/HTL unipolar or differential.
Each group of (input or output) module can be galvanic isolated, if an external power is provided
High working frequency (greater than usual encoder working frequency)
TC-SPLIT Module can be mounted on DIN Rail
Module is powered by a DC source voltage, between 10 to 30V. Typical power is less than 0.5W
(without encoder or loads)

Notes:
(1) No load on A/B/Z outputs, no encoder powered
(2) NL1: Logic level 1 (active), NL0: Logic level 0 (inactive)
(3) On 5mA load
(4) On 10mA load, supposing 24Vdc power, if not Vo= Vpower -3V
(5) No condensing
Use shielded multipair cables.
Each pair must be affected to a signal and its complement (example: A+, A-). Cable
shielding should be tied to earth on the electric box. As a good practice, you should
separate power cable from instrumentation signals. Power cable cross-section should
be of sufficient size if module is powered by 5Vdc (avoid this if distance is superior
greater than 5 meters)

Unipolar wiring must not be used with long cabling distance or within high electromagnetic
environments.
Input voltage must not be greater than 8V if switches are in low position
Never set jumpers vertically
Never set external power on [P1.7; P1.8] if jumpers are populated
Wiring colours used above are not standardized, double check datasheet of the
encoder for correct wiring
After module power up, it is possible to check the operation by slowly moving the
encoder axis, the 3 leds on the side of the TC-SPLIT should blink.
