• HART communication: Available

Notes:

• 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.
• The module input resistance viewed from the terminals depends on the current strength as calculated.
• When this module is installed to an ER bus node unit with HART function, the EB401 firmware must be rev. 2 or later.
• When the dedicated cable is used, the withstanding voltage is 500 V AC (between the input signal and the system). When the MIL connector cable is used, the withstanding voltage depends on the electrical specifications of the cable.
• This voltage is generated between the connecting terminals for 2-wire transmitters for this module. When calculating the minimum operating voltage for transmitters, consider allowing margins for voltage drop in external wiring.
