LED Industrial Hmi Panels 480*272 Pixels 300cd/M² SD Card IP65 Optional Audio
Human-Machine Interface (HMI) connects industrial control equipment such as programmable logic controllers (PLC), frequency converters, DC speed regulators, and meters. It is a digital device that uses the display screen to write working parameters or input operating commands through an input unit (such as a touchpad, a mouse, etc.) to realize information interaction between humans and machines. It consists of two parts: hardware and software.

1.Precautions of using PLC transistor and relay
The PLC output is a common cathode output, the theoretical value is
1A, the actual use is less than 500mA, the COM wiring is negative,
please use 24V voltage, there is no voltage output when it is used
as a switch. If an external relay, the relay needs an external
power supply.
The relay has a contact life, the theoretical value is 30W times,
and the theoretical value of the external load does not exceed 5A.
Frequently, the full load current may affect the service life, and
there is no voltage out.
2.Precautions of Coolmay PLC output type selection
MT: indicates the transistor output, MR: indicates the relay
output, and MRT: indicates the relay transistor mixed output.
The main differences between transistor output and relay output
are:
(1)The difference in current load. At present, we use a transistor
with a maximum current load of 500MA, and the maximum current load
of the relay is 5A (the maximum relay current of the
EX2N(S)/DX2N(S) series PLC is 3A);
(2)Output power: The transistor can only be connected to the DC24V
power supply , and the relay can be connected to the DC24V and
AC220V power supply ;
(3)Functional characteristics: If you need to send a pulse to drive
a stepper motor, you should use the transistor output or the mixed
output. Also if the output switch is active, it is recommended to
use a transistor output;
(4)If both the relay and the transistor are available, it is
recommended to use a transistor output because the transistor has
no contact life limit and the lifetime will be longer than the
relay as long as the current does not exceed the limit.
