Digital FSK allows additional information
to be carried on the same pair of wires
with the 4-20 mA Analogue Signal
Simultaneously and Transparently
4-20 mA

Getting HART into Plant Systems
3
• Some control systems offer direct HART interface and support use of HART data through-out
• For I/O systems that are not HART enabled a third party product support is required
• Gateways - HART to Ethernet, HART to Modbus, HART to Profibus, more...
• Single Device Interfaces - Transform digital process variables and status alerts into 4-20mA signals and/or contact closures
• Multiplexers - Some integral with FTA
