The center pin is positive (+).• Power over Ethernet (PoE) with power classification Class 2, via the network cable. This will automati-cally be detected if available via the network.• The power connector block on the rear panel.Power Connector BlockThe power connector block supports both AC and DC input power.The DC supply is 7-24V. Connect the negative pole to the GND pin and the positive pole to the DC+ pin.Pin Function Description1 Output A On the external device output terminals (A and B), there is no distinction between positive and negative(+ and -). The terminals use a photocoupler and are electrically isolated from the other internal circuitry.The maximum load should not exceed 100mA and the maximum voltage should be not more than 50VDC. Note: Connecting AC to the output will damage the unit.2 Output B3 Digital Input 1- Photocoupler Anode (+) Photocoupled Input 1. Electrically isolated from the chassis and connectors, this input can be suppliedfrom an external DC voltage or the DC Power Input/Output on pins 9 (DC+) and 10 (GND).4 Digital Input 1 - Photocoupler Cathode (-)5 Digital Input 2 - Photocoupler Anode (+) Photocoupled Input 2. As above.6 Digital Input 2 - Photocoupler Cathode (-)7 RS-485-A (non-inverting) A half-duplex RS-485 interface for controlling auxiliary equipment.8 RS-485-B (inverting)9 DC + Power Output This can drive the photocoupler inputs or other equipment. The output voltage level is 3.0 V. A maximumcurrent of 100mA can be sourced from the DC output.10 GND Ground.
