Yokogawa|AAI841-H00/K4A00|Current/Voltage I/O Module (Non-Isolated)
Yokogawa AAI841-H00/K4A00 Current/Voltage I/O Module (Non-Isolated)
The Yokogawa AAI841-H00/K4A00 is a non-isolated analog I/O module providing 8 current inputs and 8 current outputs, supporting 4–20 mA signals for up to 8 control loops with dual-redundant capability.
Features
Supports per-channel configuration for 2-wire or 4-wire transmitters via hardware pin settings. Offers HART communication when installed in an ER bus node unit with EB401 firmware revision 2 or later. Not compatible with Zener barriers; requires isolation barriers for intrinsically safe applications.
