Voltage range can be expanded with a LJTick-Divider.
Can be configured for -10V to +20V range.
According to actual measured data, see related Noise and Resolution (App Note)
Useful LJTicks for analog inputs are the InBuff, InAmp, Divider, and the CurrentShunt
The T4 has 4 high voltage (±10V) and up to 8 low voltage (0-2.5V) analog input lines

LabJack also makes several accessories to assist in measuring a variety of analog signal sources. Useful accessories for analog inputs are:

Mux80 - Multiplexes the analog input channels to provide up to 84 analog inputs.
LJTick-InBuff - Useful for measuring super weak signals.
LJTick-InAmp - Useful for amplifying low voltage signals.
LJTick-Divider - Useful for measuring high voltage signals.
LJTick-CurrentShunt - Converts 4-20mA signals into measurable voltages.
LJTick-VRef-41 - Produces a stable 4.096V signal commonly used as an excitation voltage.
LJTick-VRef-25 - Produces a stable 2.5V signal commonly used as an excitation voltage.
