  • Viking RIng/Loop Telephone Detector Relay LDB-2


The LDB-2 is a Telephone Relay that monitors an analog phone line for ringing or an in-use condition. A built-in relay can be activated when either of these conditions are detected. This is ideal for monitoring line status or for providing a visual indication of such.

When monitoring for ring, an internal pot can be adjusted to allow the relay closure to stay on steady, or follow standard ring cadence.

The LDB-2 comes complete with a 12 VDC power adapter, and can also provide 12V DC power through its auxiliary 12V DC output terminals.
