The USB-2404-UI from Measurement Computing, Norton, MA, offers simultaneous sampling at up to 100 S/s, per channel, on four 24-bit channels of universal analog input. The device is designed for multi purpose testing, and can measure voltage, current, thermocouples, RTDs, resistance, and bridge-based sensors. The device features a built-in thermistor for cold-junction compensation, and a six-position spring terminal that allows different measurement types to be performed on each channel. It includes channel-to-channel isolation to protect the entire system from harmful voltage spikes and eliminate measurement errors caused by ground loops. It also includes 250 Vrms channel-to-channel and channel-to-ground isolation, and does not require an external power supply. TracerDAQ® software acquires and displays data, and generates analog signals.
