1. Function introduction
1.1 Function overview
GC-4674 (4-channel analog output module, 0V~+10V) can be used to output signals
in the range of 0V~+10V. This terminal module can provide electrical isolation
signals with a resolution of 12 bits for the processing layer. The GC-4674 module has
2 two-wire output terminals, which are especially suitable for installation in a control
cabinet to save space. The GC-4674 module has a common ground potential terminal,
and the power contacts are connected together. The reference ground of the output
terminal is the 0V power contact.
1.2 Performance characteristics
●The number of output points is 4;
●The signal voltage is 0V~+10V;
●Power supply via GC-bus;
●The measurement error is less than ±0.1% (full scale);
●The measurement resolution is 12 bits;
●The conversion time is about 4ms;
●The electrical isolation is 1500 Vrms (GC-bus/signal voltage);
●GC-bus current consumption is 150mA;
●The bit width output in the process image is 4x 2 bytes;
●Configuration without address settings, through the bus coupler or controller
configuration;
●Applicable to all GCAN-PLC-400 series and GCAN-8000 series bus terminal
modules;
●Working temperature range: -40℃~+85℃;
●Size: length 100mm * width 69mm * height 12mm.
1.3 Typical application
●The standard analog signal can be output according to the instruction;
●It can be used to adjust the opening of valves, gates and other control equipment;
●Connect to the bus coupler or controller to realize the transmission of analog
signals.
2. Equipment installation and use
This chapter will explain in detail the installation method, wiring method, meaning of
the indicator light and the meaning of the interface of the GC-4674 module.

2.1 Module fixing
The installation method of GC-4674 module is shown in Figure 2.1. You need to use
a flat-blade screwdriver to assist in installation.
Figure 2.1 GC-4674 module installation
First, you need to install the fieldbus coupler on the rail, and then attach the GC-4674
module to the right side of the fieldbus coupler or other modules to add this
component. Please insert the GC-4674 module inward along the slot as shown in
Figure 2.1 until the lock catches.
The GC-4674 module is powered by GC-bus, no additional power supply is required.
You only need to connect the power supply to the bus coupler and connect the
GC-4674 to the module composed of the bus coupler to realize the power supply of
the GC-4674.
2.2 Wiring method
As shown in Figure 2.2, first insert a flat-blade screwdriver into the square hole and
hold the screw in the square hole. Then insert the cable into the circular hole. After
plugging it in, pull out the screwdriver and the cable can be firmly locked in the
circular hole.

Figure 2.3 GC-4674 module wiring terminal block
The wiring terminal block of GC-4674 module is shown in Figure 2.3. GC-4674
contains 2 groups of output points, and can connect to 2 groups of analog signals at
most. The serial numbers corresponding to each terminal and their meanings are
shown in Table 2.1.

Table 2.1 Indicators of GC-4674 module
2.3 System status indicator
The GC-4674 module has 2 running indicators to indicate the running status of the
device. The specific indication function of the indicator light is shown in Table 2.2.
When the indicator is on, the status of the GC-4674 module is shown in Table 2.3.

2.4 Use in combination with PLC400/510 series
GCAN-PLC-400/510 supports programming in five languages. The following uses ST
language as an example to introduce how to use GCAN-PLC-400 to program and
write the status of the analog output of the GC-4674 module.
When GC-4674 module performs ST programming definition, it is necessary to define
the variable type, output signal position, start character, separator, etc. For example:
"AO AT%Q0.0:INT;", where "0.0" represents the start address of the first channel,
each channel occupies 2 bytes, 0V~+10V corresponds to 0~4095, so the second
channel’s The starting address is Q2.0. When the user uses more than one GC-4674
module, the second GC-4674 needs to be defined from "Q8.0", because each 4674 has
4 channels; "%" (percent sign) is the direct variable start symbol : ":" (semicolon) is a
variable or type separator. Use the symbol variable AO to write the signed integer
from the %Q0.0 address. AT stands for the address of variable access and the

Vhandy Technology GC-4674 user manual
additional attributes of the variable
(Note: Input only affects input, output only affects output, and output and input do not
affect each other. That is, if there is and only an input module in front of the output
module, then no matter how many input modules there are in front, the address of the
first output module is still Q0 .0.)
2.5 Combination with GCAN-IO-8000 series equipment
The status of the analog output is represented by two bytes. For example:
GCAN-IO-8000 module node number is 1, if you want the input state of channel 1 of
the first GC-4674 module to be +5V, and the input state of other channels are all 0V,
you need to set the GCAN-IO-8000 module Write CAN data frame ID is 0x201, data
length (DLC) is 8, frame data is 0xFF, 0x07, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00
data.
