Wiring the Differential Input Terminals

The direct-current signals ranging in voltage from 5 V to 24 V can pass through the high-speed input terminals

X0.0+~X0.3+, X0.0-~X0.3-, 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.

4.13.5.2 Transistor Output Circuit

Direct-current power supply

The output terminals of a transistor module are open-collector output terminals. If Y0.8 is a pulse train

output terminal of a transistor module, the output current passing through its output pull-up resistor must

be greater than 0.1 A to ensure that the transistor module operates normally.

A relay or a solenoid valve is used as a DC load. A diode is connected in parallel to absorb the surge

voltage which occurs when the load is OFF.
