Technical Specifications

Output Signal and Channel Configuration

The AAI543-S50/A4S00 provides 16 isolated analog output channels, each delivering a 4-20 mA current signal. These outputs allow the control system to transmit analog commands to connected field devices. For example, a controller can use the current output to regulate a valve positioner or another device that accepts a 4-20 mA reference signal.

Furthermore, the allowable load resistance of 0 to 750 ohms defines the permitted external circuit load. When selecting connected devices and wiring, ensure that the total loop resistance remains within this specified range.

HART Communication and Output Monitoring

The module supports HART communication, allowing digital communication alongside the 4-20 mA analog signal. This provides an additional communication channel for supported field instruments without replacing the standard analog output function.

In addition, the module provides circuit-open detection below 0.65 mA. This feature helps identify an open output circuit, which is important when checking field wiring and connected device conditions.

Model Configuration

The ordering code identifies the module configuration:

The complete ordering number is AAI543-S50/A4S00. Therefore, verify the suffix when replacing an existing module to ensure the terminal block configuration matches the installed hardware.
