Does the HART multiplexer interfere with the DCS communications?
This family of HART interfaces have a proven track record in hundreds of installations worldwide, and have been designed from the ground up to provide connectivity between AMS Device Manager and HART instruments in the field without compromising the integrity of the 4-20 mA signal used by the DCS or PLC. HIS is by far the most elegant, cost-effective and concise solution for HART connectivity. The fundamental design premise for the HART Multiplexer is the notion that the control and maintenance plant environments are two separate entities. Elcons termination panels and HART multiplexers are designed to provide maintenance personnel with the HART information they need without compromising the integrity of the control system. The termination panels are passive in nature, just providing a connection path between the inputs and the outputs. The HART muxes are connected to the circuit in parallel, and provide three port isolation as well as dual capacitors for high integrity. While using an
