Wiring differential input terminals
The direct-current signals ranging in voltage from 5 V to 24 V can pass through the high-speed input
terminals X0.8+~X0.15+, and X0.8-~X0.15- on AH20MC-5A. The frequency of input signals can be
up to 200 kHz. These high-speed input terminals are connected to a differential (two-wire) line
driver.
The wiring of the differential input terminals are shown below. (The wiring is used for high speed and
noise):
