PC link protocol, RS instruction and Modbus instruction. The other one is USB interface,
which has the same function as COM0.
Power Supply Specification
The H0U series PLC adopts the DC/DC power supply.
The input voltage of the DC/DC power supply is 24 V. The outputs are +5V/+24VDD/GND
and +5V/COM respectively. +5V/+24VDD/GND provides power supply to the digital
circuits and relays of the H0U, while +5V/COM provides power supply to transistor in the
mixed output.
The DC/DC power supply adopts self-excitation to generate pulse width modulation (PWM)
square wave and uses TL431 for feedback. The power supply voltage of the main circuit is
+5V/GND.
The following table describes the power supply specification of the H0U series PLC

Input Specification
For the X terminals, the rated input voltage is 24 VDC. Relative to COM (0V), the X
terminals is OFF when the input voltage is below 4.0 V, is ON when the input voltage is
above 15.0 V and is not fixed when the input voltage is 4.0–15.0 V. On the condition of
rated input voltage of 24 VDC, the input current is 4–6 mA.

Hardware filter
The other I/O terminals except X0 to X7are hardware filter. The
filter time is about 10 ms.
High-speed function
The maximum frequency counted at X0 and X1 reaches up to 60
kHz. The maximum frequency counted at X2 to X5 reaches up to
10 kHz. The total frequency is not higher than 60 kHz.
Output Specification
For the Y terminals, the output mode is dry-contact. The output is active (state "1") when
