AAI835-H00 S1 is a Yokogawa isolated analog I/O module for CENTUM VP FIO systems, providing four 4–20 mA input channels and four 4–20 mA output channels. Its 10 ms data update period supports responsive control-loop processing, while 500 V AC channel and system isolation strengthens signal integrity. The H suffix identifies integrated HART communication for compatible smart field devices. This Yokogawa analog current I/O module helps connect transmitters and valve positioners to a field control station through a channel-isolated architecture. It is designed for dependable process signal acquisition and command output in distributed control system environments. For replacement, maintenance, and expansion projects, this module helps preserve established CENTUM VP automation infrastructure.
— HART communication for compatible smart field instruments.
— 2-wire or 4-wire transmitter arrangements.
— Dual-redundant configuration support.
— 4–20 mA valve positioner control.
— FIO maintenance, retrofit and expansion.
