Product Description
The AAI543 (P/N: AAI543-H61/K4A00) is a high-reliability analog output module for the Yokogawa CENTUM VP and ProSafe-RS control systems. It provides 16 fully isolated current output channels (4–20 mA), converting digital control logic into precise signals to drive actuators, valve positioners, and other final control elements.
The H61 revision supports dual-redundant operation for high-availability systems, with HART digital communication for remote device management, diagnostics, and predictive maintenance. The module comes pre-fitted with the ATK4A-00 KS cable interface (K4A00 option), enabling rapid connection to DCS terminal boards and reducing cabinet wiring time.
