HART Multiplexer for online configuration and diagnostics of HART-compatible field devices, as well as for continuous documentation of process variables and states with a PC or management system for mounting on NS 35/7.5 or NS 32 

## Product Features 

Supports online configuration and diagnostics for the connected HART-compatible field devices 

Communication via software tool (e.g., HART OPC server) using RS-485 interface 

Up to 128 HART multiplexers on one PC interface 

32 HART channels per multiplexer 

Continuous documentation of process variables and states 

Electrical isolation between auxiliary voltage, RS-485 bus, and the HART channels 

HART field devices are accessed parallel to the transmission of the measurement signal without affecting measured value processing 

HART field devices connected via universal HART connection boards; direct connection if processing non-Ex signals, with separate Ex i signal isolator connected upstream if processing Ex signals 

Power supply via HART connection board
