Main features of the H2U series PLC:
☞☞Built-in large program memory space without an external extension memory
card can reach up to 24K steps.
☞☞An internal large-capacity power supply can directly provide power to externally
connected devices such as sensors, HMI, and external auxiliary relays.
☞☞It provides high-speed, multi-channel and high-frequency I/O terminals, and has
rich operation and positioning control functions.
☞☞It integrates four independent communication ports, which support multiple
communication protocols including MODBUS instruction and are convenient for
system integration.
☞☞It provides comprehensive encryption function that can protect users’ intellectual
property rights.
☞☞It supports up to 128 subprograms and 21 interrupt subprograms.
☞☞It comes with fast execution speed.
Safety Precautions
Before operating the equipment, please read the safety precautions carefully so as to
ensure your safety and prevent damage to property. Installation and operation of the
product may only be performed by the authorized personnel who have been strictly
trained, comply with the precautions in the manual, and observe related industry
safety code.
Design Precautions
Provide a safety circuit outside the PLC so that the application system can still work
safely once external power failure or PLC fault occurs. Take the following aspects into
considerations in design:
☞☞Outside the PLC, an emergency stop circuit, a protection circuit, an interlock
circuit and a positioning limit circuit may be necessary to prevent damage to
your machine.
☞☞To ensure safe operation of the machine, please design external protection
circuit and safety mechanism for the output signals that may cause heavy
accidents.
☞☞When the PLC CPU detects its own system abnormality, all outputs may be
closed. When part of the controller circuit fails, related outputs may be out of
control. Thus, design an appropriate external circuit to ensure normal operation
of the machine.
☞☞If output units (relay or transistor) are damaged, related outputs may be kept on
the “ON” or “OFF” status.
☞☞PLC is designed for indoor electric environment. Its power supplies should have
lightning protection device. Ensure that lightening over-voltage is not applied on
PLC terminals so as to avoid damage to the machine.
Installation Precautions
Type
☞☞Don’t supply external power to terminal 24+ of the main unit or expansion
units. Do not wire vacant terminals externally.
☞☞Select shielded cables as high-frequency signal input/output cables in applications
with serious interference so as to enhance system anti-interference ability.
☞☞Please use wires of above 2mm² to connect the ground terminal of the main unit to
avoid sharing grounding with the heavy electrical system.
Startup and Maintenance Precautions
☞☞Do not touch any terminal while power is on. Otherwise, electric shock or
malfunction may be caused.
☞☞Make sure power supplies are cut off before cleaning or retightening terminal.
Otherwise, you may be shocked by electricity.
☞☞Please connect or remove the communication cable and the cables of expansion
modules and control unit after cutting off all power supplies. Otherwise, machine
damage or malfunctions may be caused.
☞☞Perform operations such as online modification, coercible output, RUN and STOP
after understanding the instruction manual and ensuring the safety of the machine.
☞☞When inserting or removing remote extension card, make sure that power supplies
are cut off.
☞☞Make sure to replace coin battery at power-off. If you really need to replace
the battery during power supply, let professional electrical technician wearing
insulating gloves complete replacement within 30 seconds. Otherwise, data loss
may result.
☞☞Please dispose scrapped PLC as industrial wastes.

Requirements on Mounting Position
☞☞Do not remove the paper tape that prevents foreign objects from dropping into
the unit during installation. Once installation is complete, remove the paper tape
before power-on so as to prevent overheating.
☞☞To prevent overheating inside the PLC, mount the unit in wall-hanging mode, as
shown in Figure 1. Keea a distance of 300mm at the top and bottom.
☞☞Leave a distance of 50mm or more between the main PLC module and other
devices or structures. Keep the equipment as far as possible away from the highvoltage cable, high-voltage devices and power devices.
How to Fix the PLC
The H2U Series PLC can be installed with the DIN rail or directly with four screws M4 in
a shock application.
To fix the PLC with the DIN rail, do as follows:
1) Fix the DIN rail on the backplane horizontally.
2) Pull out the DIN rail buckle at the bottom of the module.
3) Link the module onto the DIN rail, push the buckle back in position, and then lock the
module.
4) Finally fix the DIN-rail to two sides of the module so as to avoid sliding around.
Electrical Design
Here is the configuration of main module input and output terminal blocks of the H2U
Series PLC. Relay and transistor, output type of the PLC, share the same terminal
configuration.

PLC has a built-in power supply (DC24V) to detect user switch status, so you only need
to connect input signals of dry contact. OC output type is needed if you connect an active
transistor or sensor.
PLC signal input and internal equivalent circuit are shown as Figure 4 below. User’s circuit
and PLC internal circuit are connected by the terminal. Figure 4 shows the Sink input
mode, determined by short connection of “S/S” ” and “24V terminals.

Sink/Source mode. It is sink input when S/S terminal and 24V are shorted
connection, it is source when s/s terminal and COM are shorted connection.
It’s suggested that you loosen one screw about half and then loosen the other one.
Alternately loosen them until both are completely loosened. Then gently raise up the
terminal block. Remember not to loosen the two screws one by one.
To mount a terminal block put terminal pins into correct position and then slightly
tighten one screw. After ensuring the screw doesn’t fall off, tighten the other one.
Alternately tighten them until they are fixed. During the process, insert the two sides of
the terminal block as balanced as possible. Otherwise, terminals may damage, which
may cause bad contact or short circuit.

The H2U Series PLC has relay output and transistor output. Their operating parameters
are quite differently. Please select the correct output type so as to avoid misuse.
The main module and active expansion module provide power to expansion modules,
extension cards and adapters. The I/O points of expansion modules and the number of
special function expansion modules must be within the power supply capacitance of the
main module or active expansion module.

In some special applications, Source input mode may be required. The equivalent input
circuit of such mode is shown as Figure 5. S/S and COM terminals are shortly connected.
Figure 6 shows the internal equivalent circuit of the relay output module. The output
terminals are divided into several groups. The groups are electrically insulated. The output
contacts of different groups are connected with different power circuits.

The internal equivalent circuit of transistor
output is shown as Figure 7.The output
terminals are divided into several groups,
and the groups are electrically insulated.
The transistor output can be used for
DC24V load circuit only.
For the inductive load in AC circuit, you
need add a RC component instead, and
for the inductive load in DC circuit, you
need add a freewheeling diode, as shown
in Figire 8.

For calculation on power supply capacitance, take the following aspects into
considerations:
☞☞Each power supply capacitance should be calculated independently.
☞☞The expansion capacity is decided by the smaller power supply capacitance.
For example: 24VDD allows connection of 6 expansion modules, while +5V only allows 8
expansion. So the system can only be extended up to 6 expansion modules.

via on-site wiring by users. For the COM1/COM2 definition, see Figure 3.
Note: Both ports are supported only half-duplex communication mode.
COM3 port of H2U-XP can be available through extension card.

Terminal Block Definition
To protect the PLC output relay contacts, for inductive load (such as relay coil) in DC
circuit, the user circuit must have a freewheeling diode. For inductive load in AC circuit, the
user circuit should have a RC surge absorption component. In principle, the relay output
should not be connected to a capacitive load. If necessary, make sure its impact of the
surge current is smaller than the maximum current of the relay’s specification.
The current of transistor output terminals must be less than the allowable maximum
current. If the output current of multiple transistor terminals is greater than 100mA, they
should be evenly arranged but not be arranged adjacently, convenient for heat radiation.
It is suggested that the output points in ON state simultaneously do not exceed 70% of
total output points for long.

Communication Interface Definition
The H2U PLC main unit has two communication ports (H2U-XP has four communication
ports). COM0 hardware is standard RS422, selected by jumper JP0. If JP0 is connected,
RS422 is selected. If JP0 is disconnected, the RS422 and RS485 are compatible. COM0
hardware of H2U-XP is standard RS422, which cannot be connected with JP0. Otherwise,
the PLC cannot work normally. The terminal interface is Mini-DIN8 socket.

When designing an H2U Series PLC system, we must consider the following aspects:
☞☞Total I/Os should be within 256 for a main PLC system.
☞☞Power supply capacitance (see 3.3 for details)
The main modules and the active expansion modules can provide DC24V and
DC5V power supply to expansion modules and special modules. But total power
consumption of all expansion units should be restricted within the power supply
capacitance of main module or the active expansion module.
☞☞The H2U Series main module can be connected to maximum 8 special modules.
