Yokogawa Analog Output Module Aai543

Product Specifications/Features
    Yokogawa Analog Output Module AAI543

    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)

    Items Specifications
    Model AAI543
    Number of output channels 16, isolated, standard switch-over
    response in redundant configuration (*3)
    Output signal 4 to 20 mA
    Withstanding voltage Between output and system: 1500 V AC, for 1 minute (4)
    Allowable load resistance 0 to 750 Ω
    Circuit-open detection Less than 0.65 mA
    Accuracy ±48 μA
    Data update period 10 ms
    Drift due to ambient temperature change ±16 μA/10 C
    Maximum current consumption 230 mA (5 V DC), 540 mA (24 V DC)
    Weight 0.4 kg
    External communication Pressure clamp terminal, MIL connector Cable, dedicated cable (KS1)
    HART communication (5) Available
    *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.
