  • Page 11: Difference Between Eh-rmp2 And Eh-rmp

    EH-RMP2 : Not built-in (Please use a connector which has a termination switch.) EH-RMP2 expands the input and output size to use in PROFIBUS network in comparison with EH-RMP. For this reason, inspite of standard mode / compatible mode, the input data of the PROFIBUS network may be rarely affected under noise environment.
