Dry Contact Input Relay Module

Recommended Posts

Hello,

I have a Hikvision IP camera with a solid state relay output. This allows small amounts of voltage to pass though the open contact which is ruining a planned integration to an electric strike. It is enough voltage to hold a relay coil once it has been opened. I have tried resistors or diodes, but then the voltage drops too much to trigger the coil.

 

I have made this work with various access control panels with a dry contact input. For some reason these systems are not as sensitive to small amounts of bleed. Does anyone know of a dry contact triggered relay? Currently I have this set up with an Altronix ACM4, but that is too big and total overkill for such a simple thing.

 

Any help or comment appreciated.

 

Thanks,

 

Seth
