Product Description
Model: ASI533-S00, Yokogawa FIO analog output module with built-in intrinsic safety barrier for CENTUM VP / CS3000 DCS system. It is an 8-channel isolated AO module, converting DCS digital control commands into 4~20mA DC analog signals to drive field control valves and positioners. This module is equipped with built-in IS barrier and pressure clamp terminals, certified for intrinsic safety. It can connect to field instruments in hazardous areas directly and serves as key I/O spare part of Yokogawa FIO series.

Application
Widely deployed in DCS control systems for oil, chemical, natural gas, refinery, power plant and pharmaceutical process industries. It sends 4-20mA signals to control regulating valves, solenoid valves and valve positioners. Suitable for PID control loops for flow, level and pressure regulation in hazardous locations. Used for new DCS projects, system expansion, spare parts replacement and retrofit & maintenance of legacy CENTUM CS3000 systems.
