9000 series from PR Electronics SIL 2-certified

28 July 2008

With six different I.S. interfaces, the 9000 series covers every common I.S. application. These interfaces can be installed in zone 2 / div. 2 and carry the following approvals: IEC Ex, ATEX, FM and GOST Ex.

PR Electronics’ new I.S. series offers user-friendly technology, which supplies and monitors the I.S. interfaces with a minimum of wiring. The power control unit detects alarm signals from the modules on the power rail, and each module has a status relay for individual surveillance as well as a relay for collective surveillance via the power rail.

The I.S. interfaces provide signal conditioning with 2.6 kVAC galvanic isolation and have far better EMC performance than required by the EMC directive (IEC 61326) and NAMUR NE21, as these interface also comply with IEC 61326-3-1 (EMC for functional safety). In addition, the 9000 series complies with NAMUR NE43 (sensor error) as well as the Low Voltage Directive and carries marine (DNV) and UL 61010-1 approvals.
