Wiring the differential inputs
The direct-current signals ranging in voltage from 5 V to 24 V can pass through the high-speed
inputs X0.0+~X0.3+, and X0.0-~X0.3- on AH10PM-5A. (Only 24 V DC signals can pass through the
other inputs in AH10PM-5A.) The frequency of input signals can be up to 200 kHz. These
high-speed inputs are connected to a differential (two-wire) line driver.
The wiring of the differential inputs (used for the high speed and noise):

If the frequency of input signals is less than 50 kHz and there is not much noise, these high-speed
inputs can be connected to the direct-current power supply whose voltage is within the range
between 5 V and 24 V, as shown below.
