Signal isolator gets CSA International approval
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 2-wire HIX provides superior 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. The HIX protects I/O cards from surges and spikes, provides area isolation to allow loops to continue working during system maintenance downtime and provides a safe method of sharing a HART signal.
The cCSAus certification allows the HIX to be used in hazardous conditions where flammable gas or vapors 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.
