Moore Industries HIX HART loop isolator

Click2Contact

The HIX HART loop isolator provides loop isolation while allowing the HART signal to pass through uninterrupted.

It provides economical solutions to three common and costly problems that plague many of today’s smart HART loops. It can be used for splitting the HART output of one transmitter safely between a DCS and safety system without further burden on, or risk to, the primary safety loop. It can also be used for surge, spike and transient safeguarding to protect I/O cards - the 1500 V_RMS isolating capability of the HIX breaks the galvanic path that can pass dangerous overloads from DCS to transmitter to PLC or vice versa, even when equipment is supposedly isolated already. It also enables area isolation to allow for equipment maintenance without loop downtime, and allows HART devices on isolated legs of a loop to be removed from the circuit without affecting other equipment.

The HIX HART signal isolator from Moore Industries has received General Location and Class I, Division 2 (non-incendive) approvals from CSA International in the United States and Canada. The cCSAus certification allows the HIX to be used in hazardous conditions where flammable gas or vapours are present in the atmosphere, such as petroleum refineries. The approval covers Groups A, B, C and D and temperature code T4A at an ambient temperature of -20 to 70°C.
