Centralized access to up to 32 HART devices on existing 4...20 mA loops in a control-room-connected maintenance system.
Eliminates the need to rewire field instruments for HART diagnostics and configuration.
Used where the HART communications interface must fit a safety-conscious process architecture with low power dissipation and defined installation on a termination board.
Provides a structured multiplexer layer for diagnostic access without disturbing loop operation.
Fits existing HART-enabled instrumentation networks where long-installed 4...20 mA wiring needs centralized monitoring and maintenance access.
Enables modernization of legacy analog loops without replacing field cabling or instruments.
