Yokogawa Analog Output Module AAI543-S53 

   STANDARD SPECIFICATIONS of AAI543-S53 

   Current/Voltage Input Modules (Non-Isolated)
   These modules provide 16 inputs of mainly 4 to 20 mA DC or 1 to 5 V DC standardized signals from 2-wire/4-wire transmitters.
  They can be used in dual-redundant configuration.

      Current Output Module (Isolated)      

     AAI543  provides 16 outputs of 4 – 20 mA signal. It can be used in dual-redundant configuration. (*1)  

  *1: A dual-redundant configuration is enabled by using two identical modules with the same suffix codes.
*2: When AAI543 is installed in a ER bus node unit, use it in the ambient temperature within 0 to 60 ºC range.
*3: When a switch over from control to stand-by module takes place in the dual-redundant configuration, the maximum period
of time when the field output falls below 4 mA is 100 ms for AAI543-0 (standard switch-over response) and 2 ms for
AAI543-1(fast switch-over response). In case of connecting fast response type field devices, use AAI543-1 (fast
switch-over response) in the dual-redundant configuration.
*4: When the dedicated cable is used, the withstanding voltage is 500 V AC (between the input signal and the system). When
the ML connector cable is used, the withstanding voltage depends on the electrical specifications of the cable.
*5: When this module is installed in a ER bus node unit with HART function, the EB401 firmware must be rev. 2 or later.
