Technical Description
The KS10-03*A is a high-density, multi-core signal interface cable designed by Yokogawa for connecting FIO modules to remote terminal boards in CENTUM VP and ProSafe-RS systems. Featuring a 50-pin male-to-male connector configuration, the cable carries 32 discrete input/output channels in a single harness. Its construction emphasizes EMI and crosstalk reduction, ensuring reliable signal transmission in high-speed, noise-sensitive industrial environments. The 25-meter length (suffix code “25”) provides flexible routing between cabinets and field junctions.

Operational Application
The KS10-03*A simplifies I/O wiring by replacing multiple point-to-point connections with a single pre-fabricated harness. It is widely used in petrochemical plants, water treatment facilities, and power generation sites, where high I/O density and signal integrity are critical. Its 25-meter reach allows flexible routing between main cabinets and local junctions or terminal boards, reducing installation time and minimizing human wiring errors.
Frequently Asked Questions
Can the 25m cable be shortened if there is excess slack?
Physically possible, but not recommended. Cutting the cable compromises connector integrity, shielding effectiveness, and may void certification compliance.
What is the difference between Style A and other style codes?
The Style code defines pin assignments and connector orientation. Using the wrong style can invert signals or create short circuits.
Does this cable support hot-plugging?
While FIO modules may allow hot-swapping, it is recommended to de-energize the terminal board before connecting or disconnecting the KS10-03*A to avoid transient voltage spikes.
