I/O Terminal connector

The 10-pin I/O terminal connector provides the interface to a solid state relay output, two digital photo-coupled inputs, RS-485, GND and auxiliary power.

The terminal connector is used in applications for e.g. motion detection, event triggering, time lapse recording, alarm notification via e-mail, image storage to FTP locations, etc.

•Input - Used for connecting external alarm devices and triggering images for specific alarm-based events. The input is typically connected to a motion detector or any other external security device, and images can be uploaded whenever the detector is activated. Maximum 18VDC is allowed on the input.

•Output - This can drive a maximum load of 50VDC or 35VAC at 100mA directly or heavier loads by connecting additional relay circuitry. If the output is used with an external relay, a diode must be connected in parallel with the load for protection against any voltage transients.

Caution!

Connecting AC to the inputs/outputs will damage the unit.
