The HIX HART signal isolator recently received certification from third-party testing organization CSA International for use in general locations, and in Class I, Division 2 (non-incendive) industrial areas. The two-wire HIX provides superior loop isolation while allowing the HART signal to “pass through” uninterrupted, the company says. The HIX provides solutions from three common and costly problems that plague many of today’s smart HART loops: it protects I/O cards from surges and spikes; it provides area isolation to allow loops to continue working during system maintenance downtime; and it provides a safe method of sharing a HART signal. The CSA approval allows the HIX to be used in hazardous conditions where flammable gas or vapors are present in the atmosphere. — Moore Industries International Inc., North Hills, Calif.
