Product Description
The AAI835-H50/13S00 is a combined analog input/output module for the Yokogawa CENTUM VP control system, designed to handle signal acquisition and actuator control within a single slot. It provides 4 isolated analog inputs and 4 isolated analog outputs, all supporting 4–20 mA signals.
The H50 specification enables HART digital communication, allowing advanced field device configuration, diagnostics, and status monitoring. This model includes the /13S00 pressure clamp terminal block, ensuring secure and vibration-resistant field wiring.

Application Scenarios
The AAI835-H50/13S00 is commonly applied in PID control loops where a single module manages both transmitter feedback and control valve output. It is well suited for compact process skids, chemical plants, and offshore platforms, where space efficiency, channel isolation, and HART diagnostics are critical.
Technical FAQ
Q: Does this module support HART passthrough?
A: Yes. The H50 specification supports HART variable communication between field devices and the CENTUM VP engineering station for configuration and diagnostics.
Q: What happens to the input resistance during power loss?
A: When power is off, the module switches to high input impedance (≥500 kΩ) to prevent loop loading and avoid interference with other devices in the current loop.
