*1: Use two modules with the same suffix code for use in dual-redundant configuration.
*2: When AAI543-1 is installed in a remote node, the ambient temperature should be 0 to 60 °C.
*3: The time during which the output to the field falls below 4 mA at switch-over is 100 ms at maximum for AAI543-0
(standard response) and 2 ms at maximum for AAI543-1 (fast response).
When any fast response field devices are connected to dual redundantly configured modules, AAI543-1 (fast response) should be used.
*4: The withstanding voltage for using the dedicated cable is 500 V AC (between the input signal and the system).
The withstanding voltage for using MIL connector cable depends on the electrical specifications of its cable.
*5: When installing the module with HART function to a remote node, the firmware of EB401 must be Rev 2 or later.
