*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 applications.
*2: When the ML connector cable is used, the withstanding voltage depends on the electrical specifications of the cable.
*3: The module input resistance viewed from the terminals depends on the current strength as calculated as below:
250 Ω + voltage drop in the input protection circuit/current value
F06E.ai
*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.
*6: When this module is installed to a ER bus node unit with HART function, the EB401 firmware must be rev. 2 or later.
