Introducing the USB-2404-60

Overview: USB-2404-60 features

This user's guide contains all of the information you need to connect the USB-2404-60 to your computer and to
the signals you want to measure.
The USB-2404-60 is a USB 2.0 high-speed device that is supported under popular Microsoft
operating systems. The USB-2404-60 is fully compatible with both USB 1.1 and USB 2.0 ports.
The USB-2404-60 provides four channels of 24-bit simultaneous analog inputs.
The maximum sampling rate is 50 kS/s per channel, and the input voltage range is ±60 V, nominal.
An anti-alias filter removes noise that may be present in the signals prior to conversion. A 250 Vrms channel-
to-channel and channel-to-ground isolation protects the device and computer from ground spikes, and ensures a
reliable data stream. An on-board LED indicates the status of the device.
Field connections are made to four 2-position detachable screw terminals. Ten additional two-position
connectors are available with the optional ACC-102 connector kit.
The USB 2.0 high-speed driver transfers data at rates up to 480 Mbps. The USB-2404-60 is powered by the
+5 volt USB supply from your computer. No external power is required.
