• Rugged enclosure that can mount on a DIN rail or a bench

The Digilent MCC USB-ERB series relay interface devices support Form C electromechanical relays. Each machine is designed with a heavy-duty chassis for rugged DAQ applications. The USB-ERB08 features eight channels, and the USB-ERB24 features 24 channels. Onboard switches configure each relay group's logic polarity (active high or low) and power-on state. Switch settings can be read back with software. There are screw terminals for field wiring connections with three connections to each relay - normally open (NO), normally closed (NC), and shared (C). USB out and power out links support powering and controlling multiple MCC USB devices that support daisy-chaining from one external power source and one USB port in a daisy-chain configuration.

DAQami is an out-of-the-box data logging, visualization, and signal generation application. Data can be viewed in real-time or post-acquisition on user-configurable displays. DAQami is ideal for interactive testing, data logging, and developing applications that run for minutes or days.
