Product Description
The AAI835-S50 is a hybrid analog I/O module for the Yokogawa CENTUM VP system. It combines 4 isolated input channels and 4 isolated output channels in a single module, supporting 4–20 mA signals for both sensing and actuation.
The S50 designation indicates a standard basic module for non-hazardous environments, with flexible connectivity via pressure clamp terminals, MIL connectors, or KS1 cabling. Its isolated architecture ensures reliable operation and protection against ground loops.

Technical FAQ
Q: Can this module drive a control valve while reading a pressure transmitter simultaneously?
A: Yes. The module provides independent input and output circuitry, enabling simultaneous feedback acquisition and actuator control.
Q: Is this module suitable for redundant configurations?
A: Yes. The S50 version supports standard switch-over response, allowing use in dual-redundant I/O nests to enhance reliability and eliminate single points of failure.
