Profibus-DP Field­bus Cou­pler – HE 5812

The Fieldbus Coupler HE 5812 connects the modular Process I/O HIMOD System with a Profibus-DP network.


Central coupling module for PROFIBUS-DP connection

PROFIBUS-DP - Slave according to IEC 61158, protocol DPV1

Front interface for PC 'SmartPort

up to 62 modules per coupler with additional power modules

The con­nec­tion to the Profibus-DP is estab­lished via a 9-pin D-SUB socket.

Up to 62 I/O mod­ules can be con­nected per bus cou­pler. The mod­ules are con­nected via an inter­nal bus sys­tem. Up to 16 mod­ules can be oper­ated directly at the bus cou­pler, fur­ther­more the sys­tem can be extended by an addi­tional power mod­ule – HE 5850.


In the bus cou­pler, the areas of sup­ply volt­age, field­bus and logic are gal­van­i­cally iso­lated from each other. The sys­tem con­fig­u­ra­tion con­sist­ing of bus cou­pler and I/O mod­ules can be quickly deter­mined via the but­ton inte­grated in the front of the hous­ing. Con­fig­u­ra­tion and para­me­ter­i­za­tion of the indi­vid­ual mod­ules can be done via the field­bus as well as via the Smart­Port inter­face.
