Product Overview
The Yokogawa ST4*D module is a high-density digital output module designed by Yokogawa Electric Corporation. This module’s primary function is to receive binary control signals from a Distributed Control System (DCS) and transmit them as electrical signals to field devices. It is ST4-compatible, making it a widely used form factor for high-density DCS output modules. With isolated channels, the ST4*D helps protect the control system from field-side electrical interference, ensuring stable and safe operation in industrial environments.
