Description
DESCRIPTION
The HART (Highway Addressable Remote Transducer) High Performance (HP) Analog
Input module is a standard Ovation I/O Module that provides eight galvanically isolated 4-
20 mA analog inputs with HART transceivers. Each transceivers provides optically isolated
communication to a dedicated UART, thereby, maximizing HART communication
throughout.
Each channel may be individually configured for field powered or local powered transmitters
via user accessible jumpers on the Personality Module.
HART is a digital communication protocol designed for industrial process measurement
applications. Field measurement devices (transmitters) interface for a process control
system via an analog 4-to-20 mA current loop. HART uses a low-level frequency-shiftkeyed sine wave signal that is superimposed on the standard 4-to-20 mA process
measurement current loop. Since the HART sine wave signal is small and its average value
is zero, the current loop analog 4-to-20 mA signal is not significantly affected by the
presence of the HART signal. Using HART allows a field device to provide more than one
measurement, which is a feature not available when using only the 4-to-20mA analog
current signal.
“Smart” field devices may be described as field devices in which the analog 4-to-20 mA
signal, digital communication, and sometimes power, co-exist on the same pair of wires.
The Ovation HART High Performance Analog Input (IAH) module is a standard form factor
Ovation I/O module, which will permit Ovation to communicate with HART devices
