Yokogawa AAI543-H60 Analog Output Module

The Yokogawa AAI543-H60 is a 16-channel isolated analog output module that supplies 4-20 mA current signals to field devices. It supports HART digital communication and can operate in a dual-redundant configuration when the selected model and system arrangement support this function. The module offers standard or fast switchover response options for redundant configurations, depending on the suffix code.

Hardware Specifications

Analog Output Function

The AAI543-H60 provides 16 isolated current output channels, each using a 4-20 mA signal. The controller updates output data at a 10 ms interval, while the allowable load resistance ranges from 0 to 750 ohm. These parameters help engineers verify the module against field-device input requirements and loop resistance.

The circuit-open detection threshold is less than 0.65 mA. The specified accuracy is +/-48 uA, and ambient temperature changes introduce a stated drift of +/-16 uA per 10 deg C. These values are relevant when checking analog loop performance and signal deviation.

Redundant Configuration and HART Communication

The module supports dual-redundant operation, with the response during switchover determined by the selected model configuration. The standard switchover option and fast switchover option are distinct ordering choices. Confirm the complete model code before selecting a replacement for an existing redundant I/O installation.

HART communication is available with the digital communication configuration. The -H model code identifies the version with HART protocol support in the supplied ordering information. Confirm that the controller, field device, and system configuration support the intended HART functions before deployment.

Model and Suffix Code Identification

The supplied ordering information identifies the following configuration choices:

The suffix and option codes determine communication, redundancy switchover, explosion protection, environmental options, and external connection hardware. The complete order code should be checked against the installed module and required terminal accessories. The designation AAI543-H60 alone should not be used to infer every option listed above.

Frequently Asked Questions

Q: How many analog output channels does the AAI543-H60 provide?

A: It provides 16 isolated output channels with a 4-20 mA signal range. Each channel must be checked against the connected field device's input requirements and the specified load resistance limit.

Q: Does the AAI543-H60 support redundant operation?

A: Yes. The module supports dual-redundant configuration, with standard or fast switchover response depending on the selected suffix code. Verify the full model designation and the installed system configuration before replacement.

Q: Is HART communication available on this module?

A: Yes. The supplied ordering information identifies the -H code for the HART digital communication version. Confirm the complete model code when specifying or replacing a module that requires HART support.
