AXIS P33-VE Series Installation Guide Page 13 I/O Connectors • I/O terminal connector - Used in applications for e.g. motion detec- tion, event triggering, time lapse recording and alarm notifications. In addition to an auxiliary power and a GND pin, it provides the interface to: Pin4 Pin2 • 1 transistor output - For connecting external devices such as relays Pin3 Pin1 and LEDs. Connected devices can be activated by the VAPIX® Application Programming Interface (API), by the output buttons on the Live View page or by an Action Rule. The out- put will show as active (shown under System Options > Ports & Devices) if the alarm device is activated. • 1 digital input - An alarm input for connecting devices that can toggle between an open and closed circuit, for example: PIRs, door/window contacts, and glass break detectors. When a signal is received the state changes and the input becomes active (shown under System Options > Ports & Devices). Function Pin Notes Specifications GND 1 Ground 3.3V DC 2 Can be used to power auxiliary equipment. Power Note: This pin can only be used as power out. Max. load = 50mA Digital 3 Connect to GND to activate, or leave floating (or Min. input= - 40V DC Input unconnected) to deactivate. Max. input= + 40V DC Digital 4 Uses an open-drain NFET transistor with the source Max. load = 100mA Output connected to GND. If used with an external relay, a Max voltage = + 40V DC diode must be connected in parallel with the load, for protection against voltage transients.
