GS 01B04S10-01E

■ GENERAL The BARD intrinsic safety (IS) barriers, connected to intrinsic safety devices installed in a hazardous area, configure an IS system in such a way that electric currents and voltages delivered from a safe area into a hazardous area can be limited to prevent energy A B BARD -700 generated in the IS circuit from igniting specified A B explosive gases. C BARD-820 3 2 1

12 ¥ BARD is certified by Technology Institution of Industrial 34 Safety (TIIS), Japan. ¥ Offered in two types: BARD-600, -700, -800, and -810 Zener barriers, and BARD-820 and -830 isolated barriers. ¥ The BARD-600 is for use with a thermocouple and can ¥ BARD-800 be used with double-element thermocouples. The BARD-700 is for use with a resistance temperature A CL 1 detector (RTD) and the BARD-800, -810, -820, and -830 are for use with a 4 to 20 mA signal. B 2 ¥ The BARD-940 and -950 are power supply sets for BARD-820s and -830s. The BARD-940 consists of a C 3

single power feed unit and the BARD-950 consists of F01_6.EPS dual redundant power feed units that are mounted on a ¥ BARD-810 DIN rail through which a power rail is running. They A 1 supply power to BARD-820s and -830s mounted on the same rail. B 2 ■ SCHEMATIC DIAGRAMS C 3 ¥ BARD-600 F01_3.EPS ¥ BARD-820 A 1 Ð Power Rail + 3 (L+) Power Supply 4 (LÐ)

*1: In the BARD-700, the resistance between terminals A and 1 and that between terminals C and 3 are balanced. Be careful when connecting the receiver instrument. *2: Unnecessary when supplying power from the power feed unit(s) of a BARD-940 or -950. *3: The DC power needed for a transmitter to operate is supplied from the power supply directly connected to the IS barrier. When connecting the barrier to a power distributor, perform wiring in such a way that the distributor’s internal DC power supply is not used and the barrier is connected to both ends of the distributor’s internal 250-Ω resister.
