Pepperl Fuchs HiSHPSM HART Board

Core Performance & Industrial Application

The Pepperl+Fuchs HiSHPSM (HiSHPSM/32/MM-01) is a 32-channel HART termination board for the H-System HART interface solution.

It collects 32 unbalanced HART signal loops from field instruments and routes them over dual RS-485 links to a HART multiplexer and host system.

It supports serial or parallel field wiring options with redundant 24V DC supply and reverse-polarity protection.

A built-in slot accepts the HiDMux2700 HART multiplexer for integrated HART polling inside the interface cabinet.

Screw terminals on field and control sides simplify cabinet wiring; it mounts on DIN rail.

It is widely used as spare replacement in DCS HART instrument interface cabinets for oil & gas, chemical and power plants.
