Scope of Supply Electronic Modul in standard DIN rail enclosure Special Features • Operation of HAEHNE sensors without internal adaption resistors, e.g. for applications in potentially explosive atmospheres • For connecting intrinsically safe circuits in control cabinets Technical Data Standard enclosure protection: IP 20 Explosion Protection Technical Data Explosion protection equipment group II (2) G - C.; L~ 0 i i - U. And P. are determined by .. i i The adaption module is used in conjunction with measuring amplifiers and force measurement sensors without internal adaption resistors. The J-Box serves the purpose of adapting the sensors to - higher temperature ranges - potentially explosives atmospheres The J-Box contains the resistors required for the zero adjustment and nominal rating. The box is designed for DIN rail mounting in electrical cabinets. V1: Output voltage of strain gauge full bridge V4: Supply voltage for the strain gauge full bridge of the sensors Ordering Example: J-Box Vi-Vi + v4-V4+ HAEHNE Elektronische Messgerate GmbH ■ Heinrich-Hertz-Str.29 ■ D-40699 Erkrath Germany ■ Telefon 0211/9 2591-0 ■ Fax 0211/92591-20 http://www.haehne.de Email: [email protected]

The calibration resistors in the J-Box are specified for the corresponding sensor only and can only be connected to this sensor. Therefore, the sensor and the J-Box carry the identical measurement location designation. For example sensor 04711-5 must be connected to the J-Box 04711-5.
