Helmholz 700-751-9VK21 SSW7-HMI, MPI adapter with HMI protocol

Code: 700-751-9VK21

Brand: Helmholz

The SSW7-HMI is designed for use with operator terminals, visualizations or other third-party devices that support the HMI protocol from Siemens.

The transfer rate of the adapter is set by the protocol (from 4.8 to 115 kbps).
The SSW7-HMI is supplied with voltage via the MPI bus of the CPU. With an optional 24 V connection, it can be used anywhere else in the system.
We provide the SSW7-HMI with an additional programming interface on the connector, including a switchable terminating resistor.
Parameterization and diagnostic functions are possible using the SHTools software.
