Description:
The Yokogawa AAI543-H53 Analog Output Module delivers 16 isolated 4–20 mA outputs for driving field devices from a CENTUM DCS or FIO system, with channel-to-channel isolation and a 0–750 Ω load range. This rack-mounted I/O module is commonly installed in Yokogawa CENTUM cabinets and control panels to convert digital control signals into analog outputs for actuators, valves, and variable speed drives, and it supports HART for diagnostics and configuration of connected devices. Key specs include an accuracy of ±48 µA, a data update period of approximately 10 ms, withstanding voltage of 1500 VAC for 1 minute, and an operating temperature range of -20 to 70°C. Common replacements include Yokogawa AAI543-S00, AAI543-H03, and AAB841.
