Function
Analogue telephone line protection
: the PRC surge arrester wired in series to the
private installation input protects the telephones, the PABX, the modems
(including ADSL), etc.
Protection for 2 low-current lines without common potential or 4 lines with
common reference potential
: the PRI protects the measuring instrument and PLC
«sensor» inputs and the DC power supply inputs up to 53 V and AC power supply
inputs up to 37 V.
The input current must not exceed 300 mA.
