Product Description
The AAI143-S50/K4S00 is a high-density analog input module for Yokogawa CENTUM VP and CS 3000 DCS systems. It provides 16 channels of 4–20 mA input, designed for compact, high-volume signal acquisition. Its non-isolated (common ground) architecture maximizes I/O density, making it ideal for large-scale monitoring projects where per-channel isolation is not critical.
The K4S00 option incorporates the ATK4S-00 interface adapter, enabling direct connection to KS cables and simplifying cabinet wiring. As an S50 variant, it is a standard analog module without HART communication, offering a cost-effective solution for high-speed analog signal acquisition.

Frequently Asked Questions
What is the purpose of the K4S00 adapter?
The ATK4S-00 adapter provides a front-end interface for connecting the module to terminal boards via pre-assembled KS cables, eliminating the need for individual screw-terminal wiring.
Can this module power 2-wire transmitters?
Yes, when configured with the appropriate baseplate and 24V DC loop power, it can provide power to 2-wire transmitters.
Is it compatible with 4-wire transmitters?
Yes, 4-wire (externally powered) transmitters can be used, with wiring handled at the terminal board level.
