USB-2404-UI

The USB-2404-UI provides 4 channels of 24-bit universal analog input with integrated signal conditioning. The device can be used to measure several signals from sensors such as RTDs, thermocouples, load cells, and other powered sensors. The four channels are individually configurable, so a different measurement type can be performed on each channel. All channels are measured simultaneously at up to 100 S/s per channel.

• Voltage (±125 mV, ±1 V, ±4 V, ±15 V, ±60 V)
• Current (±25 mA)
• Thermocouple (J, K, R, S, T, N, E, B)
• RTD (4-wire and 3-wire) (Pt100, Pt1000, 3 y 4 hilos)
• Resistance (4-wire and 2-wire)
• Bridge-based sensors (quarter-, half-, and full-bridge)

The device features built-in current and voltage excitation. The excitation circuit is protected from overcurrent and overvoltage fault conditions. Each channel also has a built-in thermistor for cold-junction compensation (CJC) calculations when measuring thermocouples.

An analog pre-filter removes noise that may be present in the signals prior to conversion.

With 250 Vac channel-to-channel and channel-to-ground isolation, the USB-2404-UI protects the individual channels and connected computer from ground spikes, and ensures a reliable data stream.

An on-board LED indicates the status of the device.

Each channel has a detachable six-position spring terminal for field wiring connections.

The USB 2.0 high-speed driver transfers data at rates up to 480 Mbps. The USB-2404-UI is powered by the +5 volt USB supply from your computer. No external power is required.
