The screwdriver with a tip width of 3mm is used for
wiring of MiniPLC. The cross sections of the wires are determined according to the
following dimensions:
Connection of power supply
1 For MiniPLC10MR-A and MiniPLC10MR-A(AC type)
MiniPLCs,the rated power supply requirements are 110VAC and 220VAC(85VAC-240VAC), 50/60HZ.
At a Voltage of 220VAC, the current consumptions for each type are 26mA and 50mA.
2. For MiniPLC10MR-D/MiniPLC10MT-D/MiniPLC20MR-D and
MiniPLC10MT-E/MiniPLC20MT-E/MiniPLC 20MT-D/MiniPLC10MD-E/MiniPLC20MR-E(DC type
)MiniPLCs,the power supply requirement is 24VDC(24.4VDC-28.8VDC)
3. The power supply requirement of MiniPLC10MR-F and
MiniPLC20MR-F is 12 VDC
1 2.5mm2
2 1.5mm2
The power connection for Mini PLC
is as shown in the following figure MiniPLC10MR-A and MiniPLC20MR-A
The input to MiniPLC can be either the digital such as
on/off switches, photoelectric damper, sunshine switch, etc., or the analog such as
pressure, level element, temperature, humidity, flow, etc. The specific requirements are
as follows:
Note:
1. For MiniPLC10MR-D,MiniPLC10MT-D,MiniPLC20MR-D and
MiniPLC20MT-D which can receive analog input, analog can be input though all input
interfaces (I1-I6 or I1-Ic).They can automatically set to analog input or digital input as
which is used in the porogram.It will be recognized as analog inputs when the input
terminal is connected with AN function block, and it will be recognized as digital input
when the input terminal is not connected with AN function block.You need to set analog
input firstly when you use MiniPLC-SCADA software to supervise.
2. The analog requires 0V ~ +10V voltage signals and it
is divided equally in 0.1V proportion. In programming, all the block parameters related to
the analog are based on the minimum precision of Class 0.1.
3. It can be recognized as digital input when the input
voltage is over 10.0v,and it can not be recognized as analog input.
4. As for the input of digital , when the switch status
changes from 0 to 1, the time of Status 1 must be greater than 50ms, and when the switch
status changes from 1 to 0, the time of Status 0 also must be greater than 50ms.
Connecting Mini PLC is
shown as in the following figure:
For
MiniPLC10MR-A/MiniPLC20MR-A/MiniPLC10MR-D/MiniPLC20MR-D/MiniPLC10MR-E / MiniPLC20MR-E
/MiniPLC10MR-F/MiniPLC20MR-F MiniPLC series, the output are relays.The contacts of relays
are isolated from the power supply and input.And for
MiniPLC10MT-E/MiniPLC20MT-E/MiniPLC10MT-D and MiniPLC20MT-D MiniPLC Series,the output are
of transistor type ,provided with short circuit and overloading protection. It is
necessary to have a seperate power supply for the loads.
1. Requirements for the
relay output
Various loads such as lamp, fluorescent tube, motor,
contactor, etc., can be connected to the outputs of MiniPLCs. The max. ON output current
that can be supplied by MiniPLC, is 10A for the resistance load and 2A for the inductive
load. The connection is as the following figure:
Relay output
2. Requirements
for the electronic transistor output
The load connected to MiniPLC must have the following
characteristics:
The maximum switch current can not exceed 2A; when the
switch is ON (Q=1), the maximum current is 2A. The connection is as the following figure:
The voltage between L+ 1 and M is less than
80VDC.
Transistor output
Note: M line should be connected to M of MiniPLC power supply,
and the load should be directly connected the L+ 1 , and the load current should be DC .
