The P30117 isolation card is designed for installation in an SNC Lyte Lynx® Card Shelf or Teleline Isolator* Card Shelf. No powering is required for these passive devices.
These data isolation models provide an isolated interface for 4-wire (P30117) digital or analog data circuits. Types of digital circuits protected include rates of 2.4 kbps to 72 kbps as used in services such as Synchronet, Basic Rate ISDN and HDSL carrier frequencies.
Types of analog circuits protected include rates of 100 Hz to 200 kHz as used in analog carrier, modems, SCADA, transfer trip, tone relay control and tone signaling.
The primary function of the cards is to provide isolation from hazardous voltages while being “transparent” in the circuit. All signaling information within the specified frequency bandwidth will be unaffected. However, DC signaling is not supported. A secondary function is to provide optional connections for the loop back of DC simplexed sealing current or repeater powering on the remote (Central Office) side.
