Product Description

The AAB841-S00 is a combined analog input/output module for the Yokogawa FIO system in CENTUM VP and CS 3000 architectures. This versatile module provides 8 input channels and 8 output channels in a single footprint, offering a compact solution for high-density I/O applications where common-mode isolation is not critical.

The AAB841-S00 (Model: AAB841, Suffix: S00) is ideal for cost-effective signal acquisition and control in localized cabinet environments.

Technical Specifications

System Integration and Application

The AAB841-S00 is optimized for space-constrained node units, consolidating monitoring and control capabilities onto a single module. It is suitable for:

• Interfacing with 1–5 V voltage transmitters

• Driving control valves or actuators (4–20 mA)

• Reducing the number of required base modules and bus interfaces in dense cabinet layouts

By centralizing 16 I/O points on one card, the module improves cabinet organization and simplifies wiring.

Frequently Asked Questions

Can this module be used with 2-wire 4–20 mA transmitters?
Yes, but a 250 Ω precision resistor must be installed across the input terminals to convert the current signal to the required 1–5 V range.

What does the non-isolated design imply?
Channels share a common ground with the system logic. This is suitable for localized cabinet connections where ground potential differences are minimal. For field-side connections prone to surges or voltage offsets, an isolated module (e.g., AAI143 or AAI543) is recommended.
