H0U Series PLC User Manual
Thank you for purchasing the H0U series programmable logic controller (PLC)
independently developed by Inovance Control Technology Co., Ltd. Read the manual
carefully to be familiar with the product features and be able to use the product safely.
This manual describes the specification, features and usage of the H0U series PLC. For
the developing environment and design method of user programs, see the H0U Series
PLC Programming Manual and the H1U/H2U Series PLC Instruction & Programming
Manual issued by Inovance.
The H0U series PLC has the following features:
zIt integrates PLC and TOD programs and allows programming of control logics &
display interface.
zIt supports all the instructions of the H1U and the CAN communication protocol.
zIt reaches the user memory space of 8k steps and the maximum capacity of the user
TOD programs of 56 KB.
zIt has two independent communication ports (COM1, COM2), making it act as master
or slave.
zIt supports 6-channel high-speed inputs and 2-channel high-speed outputs (only
transistor output).
zIt supports display in both simplified Chinese and English, and switchover between
the two languages online.
zIt has a total of 25 functional keys, whose functions can be defined freely.
zIt allows you to download the PLC and TOD programs via AutoShop and HTodEditor.
Safety Information and Precautions
In Design

Provide a safety circuit outside the PLC in the application so that the control system can
still work safely even if external power failure or PLC fault occurs. Take the following
aspects into considerations in the design:
zIn the external circuit of the PLC, an emergency stop circuit, a protection circuit, an
interlock circuit of forward/reverse rotation operation, and position upper/lower limit
interlock circuit are necessary to prevent equipment damage
zTo ensure safe running of the equipment, external protection circuit and safety
mechanism must be designed for the output signals that may cause serious
accidents.
zWhen the CPU of the PLC detects an abnormality of its own system, all outputs may
efesotomas

be cut off. When a failure occurs on the controller circuit, related outputs may be out
of control. Thus, an appropriate external circuit must be designed to ensure normal
running of the equipment.
zWhen the output units such as relay or transistor are damaged, related outputs will be
out of control and be continuously kept ON or OFF. Return the AC drive with
damaged output unit to Inovance for repair.
zThe PLC is designed for indoor electric environment. A lightning protection device
must be installed for the power supply system, so that lightening overvoltage is not
applied on terminals of the PLC, avoiding damage to the equipment.
During Installation
zInstall the PLC in places free from dust, oil smoke, conducting dust, corrosive gas,
combustible gas, high temperature, condensation, wind & rain, vibration and shock.
In addition, electric shock, fire, malfunction may also cause damage and deterioration
to the equipment.
zDuring screw hole processing and wiring, ensure that no metal filing and cable end
falls into the ventilation hole of the controller, because such stuff may causes a fire,
fault, or malfunction.
zAfter installation of the newly purchased PLC is complete, ensure that there is no
foreign stuff on the surface of ventilation. Failure to comply may result in poor cooling
effect during running, which may lead to a fire, fault or malfunction.
zThe installation and wiring must be secure and reliable. Poor contact may cause
malfunction.
At Wiring

zEnsure that all power supplies are cut off before installation or wiring.
zDuring screw hole processing and wiring, ensure that no metal filings or cable end
drops into ventilation holes of the controller. Failure to comply may result in a fire,
fault or malfunction.
zPerform wiring or plug/remove the cable connector only after power-off. Failure to
comply may result in electric shock or damage to the circuit.
zDon’t provide external power supply to terminal 24+ of the main unit or expansion
unit.
zUse shielded cables for high-frequency signal input/output in applications with severe
interference to enhance anti-interference capacity of the system.
During Running and Maintenance

zConnection or removal of the communication cable, cables of the extension card and
cables of the control unit can be performed only after power-off. Failure to comply
may result in damage to the equipment or malfunction.
zThe operations such as online modification, forcible output, RUN and STOP can be
performed only after you read the manual and guarantee safety.
zTreat scrapped PLC as ordinary industrial waste.

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.
