SW-4
Local Contact Closure Switch
Trilithic's SW-4 I.F. switch is a local contact closure designed for use in the Trilithic EASy system.
Trilithic's SW-4 provides a local contact closure and a substitution I.F. signal for the auxiliary I.F. input of modulators equipped with an internal I.F. switch.
The SW-4 operates in conjunction with the LS-16P to make an alternate I.F. signal available to the modulator or processor during an EAS alert.
The SW-4 has input and output ports for the EAS I.F. signal and a small terminal block to access the Normally Open, Normally Closed and Common contacts of an internal SPDT relay.
When the EAS alert is activated, the LS-16P's control signal initiates the SW-4's internal relay. This, in turn, activates the modulator's internal I.F. switch. The SW-4's contact closure is a "fail-safe"; contact, which automatically opens and reverts to normal programming should power fail. The SW-4 is installed at the modulator’s auxiliary I.F. input. It receives power, control and the substitution I.F. signal via a single coaxial cable fed by the LS-16P.
Power and control signals are blocked internally and do not appear at the output port. This small switch measures approximately 1.5 inches by 2 inches and can easily reside on the back of the modulator and requires no additional rack space or power source.
16 output IF distribution amplifier and switch controller for EAS.
The SW-6 by Trilithic is a TTL controlled switch with two independent SPDT contact closures.
Trilithic\'s SW-IP is a network IP contact closure switch for remote switching in digital systems.
