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
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.*
