Product Overview
The ATK4A-00 is a 16-channel KS cable interface adapter developed by Yokogawa, purpose-built for FCS and DCS process control systems in industrial environments. This dedicated interface component resolves common field automation challenges, including limited analog signal expansion ports, unstable multi-channel signal transmission, and incompatible KS cable wiring configurations between field transmitters and control I/O modules. Yokogawa designed this adapter to streamline field signal collection, standardize cable connection layouts, and support reliable transmission of 4–20 mA and 1–5 V analog signals. It serves process plant operators, system integrators, and maintenance teams responsible for Yokogawa system installation, upgrades, and routine troubleshooting. This rugged adapter boosts system expandability and long-term operational stability for continuous process automation.
Core Functional Features
-
Multi-Channel Signal Expansion: Supporting up to 16 analog signal channels, this interface adapter effectively expands the signal acquisition capacity of standard Yokogawa I/O modules, meeting the multi-point monitoring demands of large-scale process production lines.
-
Enhanced Field Durability: Featuring an IP54 protection rating, the unit resists dust and splash water in workshop and field installation scenarios, delivering more reliable outdoor and on-site operation compared with ordinary IP20 interface modules.
-
Universal Analog Signal Compatibility: Fully compatible with standard 4–20 mA current and 1–5 V voltage analog signals from field transmitters, it achieves seamless signal docking without additional conversion accessories.
-
Stable System Docking Performance: Adopting standard Yokogawa KS cable specifications and mainstream industrial bus protocols, this adapter ensures low-latency, anti-interference data transmission and simplifies daily system maintenance and equipment replacement.
