Larger numbers can be housed in filter cabinets or boxes. Various models and the matching flexible connector fittings are available. Mechanical design The electrical components are incorporated in an RF-tight case of tin-plated sheet steel. Filters are available for 2 or 20 lines and for upright or flat installation on shielding wall. Model Installation Filter selection B84312C Upright Space-saving solution for installing a number of different filters. B84312C*B (2-line) B84312C*H (20-line) B84312F Low profile and thus advantage especially for just one or a few filters.

In the series of 20-line filters there are 10 of them in each case. Circuit diagram 1 Circuit diagram 2 Circuit diagram 3 Note on circuit diagrams 2 and 3: These filters are mounted with current-compensated chokes. Make sure that the forward and return line are routed paired through one filter. 4 Filters for communication lines B84312 Analog systems and control lines General technical data Rated voltage VR,AC 100 V Rated voltage VR,DC 100 V Rated frequency fR Rated current IR See characteristics Line impedance ZL See characteristics Test voltage Vtest 250 VDC, 2 s 250 VDC, 2 s Maximum DC resistance Rmax See characteristics Pass bandwidth at Z L TA = 40 °C Line/line Line/case Per line Permissible ambient temperature TA 25/+40 Climatic category (EN 60068-1) 25/085/56 Weight 560 4.5 Mechanical version C Upright for 2- and 20-line filters F Flat for 2-line filters °C 25 °C/+85 °C/56 days damp heat test g 2-line filters kg 20-line filters Filters with EMP protection: Nominal DC spark-over voltage
