3. Installation
3.1 Ambient temperature
PLC use environment temperature range: 0℃~ 55℃. When the
ambient temperature exceeds 55℃for a long time, choose a place with
good ventilation.
3.2 Installation occasion
Places free from corrosion, flammable and explosive gases and
liquids.
A firm, vibration-free place.
This PLC is designed for the application of installing environment
II standard and pollution level 2.
3.3 Installation method
The PLC shall be installed horizontally on the back of the electric
cabinet, and the distance between the PLC and the above and below
equipment or cabinet wall shall not be less than 20cm. Other direction
installation is not conducive to PLC heat dissipation, PLC can not have
heating equipment below.
DIN slot installation and fixation
The module are installed with DIN slots 35mm wide, and the extension
modules are connected by clips. After the modules are connected to
each other, push the connection card forward to the module and lock
the module. Open the DIN clasp at the bottom of the module and attach
the bottom of the module to the DIN guide rail. Rotate the module close
to the DIN guide rail and close the DIN clasp. Carefully check whether
the DIN clasp on the module is tightly fixed with the DIN guide rail, as
shown below:
3.4 Cable connect and specification
The module adopts high density IO terminal, which needs to be
connected by rotating wire and terminal table, as shown in the following
table:

4. User terminal introduction
The IO terminal of the extended IO module is 40 PIN, and users need
to be equipped with IO wire and IO terminal to use it, so they need to
buy separately. A 40PIN terminal block is adopted, and PIN is defined
as A1-20 and B1-20. The functions are shown in the following table.

The SS terminal on the PLC terminal row is used to select the signal
input mode, which can be set as the source input mode or the leakage
input mode. Connect the S/S terminal with +24V or the positive terminal
providing 24Vdc power externally, that is, set it as leaky input mode,
which can be connected to the NPN sensor. Figure 7-1 shows the
internal equivalent circuit and external wiring of the leaky input mode.

Note:There are 3 options for IN and OUT functions (User need to
choose from the extension module configuration)
Indicates input only. Lights 0-37 are fixed to indicate the input
state. The IN light is always on.

Indicates output only. 0-37 are fixed to indicate the output status.
The OUT light is always on.
Dynamic refresh indication. 0-37 displays 32 input and 32 output
states alternately IN a 4-second cycle. When the input is
displayed, the IN light is on and the output is OUT light.
7. Common problems and solutions
If the LNK light is not on, check whether the connection between
the extension module and the main module is reliable.
If there is an LNK flash, check if the extension clamshell is
fastened.
