Description
The M-949-11 Line Sense Relay is a small,
PCB-mounted loop current detector with the safety
and reliability features required for UL and British
Standard (BSI) regulated telephone applications.
The M-949-11 is designed for both North American
and international use, and offers superior protection
against voltage surges such as lightning strikes.
When connected to the voice pair (tip and ring) of an
ordinary telephone line, the M-949-11 provides a
1-Form-A relay closure in response to current flowing
through the wires. This closure can be used with
control circuitry for on-hook/off-hook monitoring, switch
hook flash detection, and rotary dial pulse counting.
The M-949-11 is ideally suited for use with the Teltone
M-959 Dial Pulse Counter and other loop-current
applications, including microprocessor-based designs.
