Advantech USB-4761 USB Data Acquisition Module

Advantech USB-4761 is an 8-channel relay and 8-channel isolated digital input USB data acquisition module designed for portable, bus-powered operation. Eight Form C relay outputs (1 A @ 30 VDC; 0.3 A @ 110 VAC; 0.5 A @ 120 VAC; 0.25 A @ 240 VAC) drive loads from the same device that reads eight isolated digital input channels with 2,500 VDC isolation and 2,000 VDC ESD protection. The 8 isolated digital input channels provide high-voltage isolation on the input side and are rated for 5–30 VDC signals. LED indicators show when relays are active, while detachable screw terminals and DIN-rail mounting support easy installation in commercial control panels. The module is compatible with USB 1.1/2.0, bus-powered, and ships with a lockable USB cable for secure connections. The USB port can supply up to 500 mA, while the USB-4761 itself typically requires up to 400 mA; if multiple devices share a hub, an external power source may be required. Software support spans C#, C++, LabVIEW, VB.Net, and other common DAQ environments, enabling straightforward integration with custom applications. You can install up to sixteen USB-4761 units in a single system because of the BoardID limitation. The unit ships with a lockable USB cable and is designed for DIN-rail mounting, combining portability with robust field deployment.
