The OM-DAQ-USB-2401 is a USB

2.0 full speed thermocouple/voltage input data acquisition module (fully compatible with both USB 1.1 and USB 2.0 ports). This stand-alone module draws power from the USB port to operate. An external power supply (optional) can be used. All conﬁgurable options (including individual channel input type and range) are software programmable. The OM-DAQ-USB-2401 has user programmable voltage inputs that range from ±30 mV to ±10V, full scale. The compact, modular packaging ensures ease of use

The compact OM-DAQ-USB-2401 is ideal for portable data acquisition applications, with accessory probes (shown L to R), KMQSS-125U-12, TMQSS-125U-12, JMQSS-125U-12.

in a variety of applications. Units can be DIN rail or wall mounted with the included hardware or easily operated on a bench. All analog input channels can be measured sequentially at about 1 ms per channel. A total of 1000 samples per second can be taken, divided across all active channels.*

*Note: At highest scan rate, 1000 samples/sec ±1% with one channel on, ±5% with all channels on.
