Line Sense Relay

The M-949-01 Line Sense relay is a small PWB- mount loop current detector with the safety and reliability features required for FCC Part 68 regulated telephone applicatoins. When connected to the voice pair (Tip and Ring of an ordinary telephone line, the M-949-01 provides a 1 Form A relay closure in response to current above 20mA flowing hrough the wires. This closure CAN be used by control circuitry for on-hook’off-hook monitoring, switchhook Flash detection, and rotary dial pulse counting. Simple in design and rugged in construction, the M-949-01 is ideally suited for use with the Teltone M-959, M-8870, M-8880, M-8888, and other loop current controlled telephone dialing recievers.
