S-LINK unit
-
Features
1. Flexible I/O layout is easily possible with
T-type multidrop wiring.
2. An enormous reduction in cabling is
achieved by using 4-wire cable consisting of two signal wires and
two power wires.
3. By using a compact FP0 PLC, further
reductions in control panel size can be achieved.
4. Units are available for FP2/FP2SH and
FP3/FP10SH.

Notes
1) For detailed information on current
consumption, refer to "Determining the Power Supply
Capacitance" in the S-LINK Design Manual.
2) For information on the booster and FAN - out,
refer to the S-LINK Design Manual.
3) The number of input and output points is
automatically reflected in input X and output Y.
