Pulse Isolators Type 9202B1., Type 9202B2. and Type 9202B3. for rail mounting are 24V powered 1 channel (Type 9202B.A) or 2 channel (type 9202B.B) isolating barriers, interfacing "Namur" sensors or contacts located in an explosive atmosphere.Pulse Isolator Type 9202B.. is supplied via terminals at the front of the module, or via Power Rail Type 9400. Removable Display Module 4501 can be used for programming of the Pulse Isolator.Ambient temperature range: -20 °C to +60 °C.
If the Pulse Isolator is installed in Zone 2, the following conditions for safe use apply:The Pulse Isolator shall be installed in an enclosure in type of protection Ex n or Ex e, providing a degree of protection of at least IP54. Cable entry devices and blanking elements shall fulfil the same requirements.Removable Display Module 4501, when connected to the Pulse Isolator, may not be damaged and shall be free of dust and moisture.Supply via the mounting rail is only allowed if Power Rail Type 9400 with Power Control Unit Type 9410 (Certificate of Conformity IECEx KEM 08.0025X) is used.
Issue No. 1:Solved discrepancies of revision and issue date in the manufacturers documents(NL/KEM/ExTR06.0039/00 -> /01). Issue No. 2: Revision change of Pulse Isolator, type 9202B, due to modifications of the input circuits, minor changes to the schematic and PCB and changes of the equipment marking, in accordance with the latest standards applied (NL/KEM/ExTR06.0039/01 -> /02)
