Diglient USB-SSR24 24-Channel Solid-State Digital I/O USB device

Features and Specifications

• Mounting rack for 24 solid state relay (SSR) modules (backplane is divided into two groups of eight modules and two groups of four modules)
• Onboard switch to configure the module type (input or output) for each module group (you cannot mix input and output modules within a group)
• Onboard switch to configure the control logic polarity (active high or low) for each module group
• Onboard switch to configure the power-up state for output modules
• Switch settings can be read back with software
• Independent LEDs at each module position to indicate the on/off status of each module
• Eight pairs of screw terminal banks for field wiring connections, with positive (+) and negative (-) relay contacts brought out to the terminals
• USB out and power out connections support powering and controlling multiple MCC USB devices from one external power source and one USB port in a daisy-chain configuration
• Rugged enclosure that can mount on a DIN rail or on a bench
• The USB-SSR24 is powered by an external 9 V regulated power supply that is shipped with the device
• Daisy Chain Support*

The USB-SSR24 provides mounting locations for 24 SSR modules. SSR digital I/O modules are relay control modules that provide 4000 Vrms 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.

*Note: Use standard/included USB cable for communications daisy chain; user-supplied custom cable required for power daisy chain

USB-SSR Series Overview

The USB-SSR08 provides mounting locations for eight SSR digital I/O modules, and the USB-SSR24 provides mounting locations for 24 SSR modules. SSR digital I/O modules are relay control modules that provide 4000 Vrms 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.

Software support includes DAQami, an optional 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 the most popular applications and programming languages including Visual C++, Visual C#, Visual Basic.NET, DASYLab, LabVIEW, Linux, and Python
