ST4*D Analog Input Card for Yokogawa CENTUM Systems

Description

TheYokogawa ST4*Dmodule is a high-densitydigital output moduledesigned byYokogawa Electric Corporation. This module’s primary function is to receivebinary control signalsfrom aDistributed Control System (DCS)and transmit them as electrical signals tofield devices. It isST4-compatible, making it a widely used form factor forhigh-density DCS output modules. Withisolated channels, the ST4*D helps protect thecontrol systemfrom field-side electrical interference, ensuringstableandsafe operationin industrial environments.
