Description:Yokogawa Analog Modules  



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 Input Modules (Isolated)

     AAI143 provides 16 inputs of 4 to 20 mA signal. It can be used in dual-redundant configuration.

*1: A Zener barrier is not allowed to be connected with this module. Use an isolation barrier when the module is used in
intrinsically safe application.
*2: The module input resistance viewed from the terminals depends on the current strength as calculated as below:
250 Ω +
current value
voltage drop in the input protection circuit
*3: When this module is installed to a ER bus node unit with HART function, the EB401 firmware must be rev. 2 or later.
*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: This voltage is generated between the connecting terminals for 2-wire transmitters for this module. When calculating the
minimum operating voltage for transmitters, consider to allow margins for voltage drop in external wiring.
