The I/O Units Connectors

I/O Terminal Connector

Pinout and Interface

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 email, image storage to FTP locations, etc.

Input - used for connecting external alarm devices and triggering images for spe- cific 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 18V DC is allowed on the input.

Output - can drive a maximum load of 50V DC at 100mA directly or heavier loads by connecting additional relay circuitry. If the output is used with an exter- nal 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.
