AXIS M30 Network Camera SeriesSpecificationsI/O connectorUse the I/O connector with external devices in combination with, for example, motion detection, event triggering, and alarmnotifications. In addition to the 0 V DC reference point and power (DC output), the I/O connector provides the interface to:Digital input - For connecting devices that can toggle between an open and closed circuit, for example PIR sensors, door/windowcontacts, and glass break detectors.Supervised input - Enables possibility to detect tampering on a digital input.Digital output - For connecting external devices such as relays and LEDs. Connected devices can be activated by the VAPIX®Application Programming Interface, trough an event or from the product’s webpage.4-pin terminal blockFunction Pin Notes SpecificationsDC ground 1 0 V DCDC output 2 Can be used to power auxiliary equipment.Note: This pin can only be used as power out.12 V DCMax load = 25 mADigital Input orSupervised Input3 Connect to pin 1 to activate, or leave floating (unconnected)to deactivate. To use supervised input, install end-of-lineresistors. See connection diagram for information about howto connect the resistors.0 to max 30 V DCDigital Output 4 Internally connected to pin 1 (DC ground) when active,and floating (unconnected) when inactive. If used with aninductive load, e.g., a relay, connect a diode in parallel withthe load, to protect against voltage transients.0 to max 30 V DC, open drain,100 mAExample1 DC ground2 DC output 12 V, max 25 mA3 Supervised input4 Digital output27
