You configure the input behavior through your DeviceNet master scanner settings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCan I connect a 2-wire DC sensor directly to the input?\u003c\/strong\u003e\u003cbr\u003eYes. The 4.8 kΩ input impedance and 8 mA requirement are compatible with most standard 2-wire DC sensors. Always verify your sensor's leakage current is below the 5V DC off-state threshold.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat is the advantage of separate commons for each I\/O point?\u003c\/strong\u003e\u003cbr\u003eHaving individual commons (8 points\/8 COM) gives maximum wiring flexibility. You can connect each input or output to a different voltage reference or ground point if needed by your machine design.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHow much current can I draw from the DeviceNet power taps?\u003c\/strong\u003e\u003cbr\u003eThe module itself consumes up to 1.2W from the DeviceNet bus. The available power for downstream devices depends on your network's total supply capacity and the number of other nodes. Always calculate your network's total power budget.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIs this module suitable for controlling small relay coils?\u003c\/strong\u003e\u003cbr\u003eAbsolutely. The 0.5A output rating is perfect for driving the coils of small industrial relays, pilot lights, or solenoid valves directly, making it an ideal interface between your network and power components.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e© 2025 Ubest Automation Limited.
