USB-SSR24 24-Channel Solid-State Relay USB Device

Digilent's measurement computing USB-SSR24 is a USB-based solid-state relay interface device. The USB-SSR24 provides mounting locations for 24 SSR digital I/O modules (not included). SSR digital I/O modules are relay control modules that provide 4000 V_RMS of optical isolation. Digital input modules sense AC/DC voltages from field devices and convert them to digital TTL signals. Digital output modules use TTL signals to switch and control AC/DC loads. SSR digital I/O modules are available to switch or sense a large range of AC or DC voltages.

The device is externally powered by an included 9 V_DC power supply. USB-SSR24 has an onboard switch to configure each module group for either input or output. Devices are shipped with all modules configured for output. Input and output modules cannot be mixed within a group. Positive and negative relay contacts are brought out to screw terminals for field wiring connections.

Software support includes DAQami, an out-of-the-box application for data logging, visualization, and signal generation. Data can be viewed in real-time or post-acquisition on user-configurable displays. Drivers are included for applications and programming languages, including Visual C++®, Visual C#®, Visual Basic® .NET, DASYLab®, LabVIEW™, and Python™.
