For the \u003cb\u003euniversal inputs\u003c\/b\u003e, you can wire either a PNP (sourcing) or NPN (sinking) proximity sensor directly - the module detects the polarity automatically. For the \u003cb\u003esourcing outputs\u003c\/b\u003e, connect your load (e.g., a pilot light) between the output terminal and the DC common (-).

You don't need to order a specific module or change hardware; just wire your sensor, and it will work.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eCan I use all 16 points (8 in, 8 out) at the same time?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eYes, the inputs and outputs operate completely independently. You can read 8 sensors and control 8 actuators simultaneously through this single \u003cb\u003e1790-8BV8BX\u003c\/b\u003e module.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWhat is the difference between sourcing and sinking outputs?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eA \u003cb\u003esourcing output\u003c\/b\u003e (like on this module) provides the positive voltage to the load. A sinking output connects the load to ground. Always match your output type to your load's wiring requirements.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eHow is the module configured on the DeviceNet network?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eYou set the unique node address (MAC ID) and communication speed (125K, 250K, 500K baud) using the rotary switches on the module's side. The I\/O data mapping is typically configured in your master scanner's software (like RSNetWorx).\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eIs a separate power supply needed for the inputs and outputs?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eYes, you must provide a separate \u003cb\u003e24V DC field power supply\u003c\/b\u003e to power the sensors connected to the inputs and the loads connected to the outputs. The DeviceNet connection provides power only for the module's internal logic.\u003c\/p\u003e\n\u003cp\u003e© 2025 Ubest Automation Limited.
