1. Function Introduction
1.1 Functional Overview
GC-4622 (2-channel analog output module, -10V~+10V) can be used to output
signals in the range of +10V~-10V. The terminal module can provide electrical
isolation signals with a resolution of 16 bits for the processing layer. The GC-
4622 module has two two-wire output terminals, which are particularly suitable
for installation in a control cabinet to save space. The GC-4622 module has a
common ground potential, and the power contacts are connected together. The
reference ground at the output is the 0V power contact.
1.2 Performance characteristics
●The number of output points is 2;
●The signal voltage is -10V~+10V;
●Power supply via GC-bus;
●The load is greater than 5kΩ (short circuit protection);
●The measurement error is less than 0.1% (full scale);
●The measurement resolution is 16 bits;
●The conversion time is about 4ms;
●The electrical isolation is 1500 Vrms (GC-bus/signal voltage);
●The current consumption of GC-bus is 150mA;
●The bit width output in the process image is 2x 2 bytes;
●Configuration without address setting, through bus coupler or controller
configuration;
●Applicable to all GCAN-PLC-400 series and GCAN-8000 series bus
terminal modules;
●Working temperature range: -40℃~+85℃;
●Dimensions: 100mm * 69mm * 12mm.
1.3 Typical applications
●Standard analog signals can be output externally according to instructions;
●It can be used to adjust the opening of control equipment such as valves and
gates;
●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, the
meaning of the indicator light and the meaning of the interface of GC-4622
module.
2.1 Module fixing
The installation method of the GC-4622 module is shown in Figure 2.1. You
need to use a flat-blade screwdriver for auxiliary installation.
Figure 2.1 GC-4622 module installation
First, you need to install the fieldbus coupler on the rail, and then attach the
GC-4622 module to the right of the fieldbus coupler or other modules to add
this component. As shown in Figure 2.1, insert the GC-4622 module inwards
along the slot until the latch snaps.
The GC-4622 module is powered by GC-bus without additional power supply.
You only need to connect the power supply to the bus coupler, and connect
GC-4622 to the module composed of the bus coupler to realize the power
supply of GC-4622.
2.2 Wiring method
As shown in Figure 2.2, use a flat-blade screwdriver to insert it into the square
hole and hold the screw in the square hole. Then insert the cable into the
circular hole. After plugging in, pull out the screwdriver, and the cable can be

Guangcheng Technology GC-4622 user manual
firmly locked in the circular hole.
Figure 2.2 GC-4622 module installation
Figure 2.3 GC-4622 module terminal block
The terminal block of GC-4622 module is shown in Figure 2.3. GC-4622
contains 2 sets of output points, and can connect up to 2 sets of analog signals.
The serial numbers corresponding to the terminals and their meanings are
shown in Table 2.1.

2.3 System statusindicator
The GC-4622 module has 4 operating indicators to indicate the operating status
of the device. The specific indication function of the indicator light is shown in
Table 2.2. When the indicator is on, the GC-4622 module status 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-4622 module.
When the GC-4622 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
starting address of the first channel, each channel occupies 2 bytes, -10V~+10V
corresponds to -32768~+32767, so the second The starting address of each
channel is Q2.0. When the user uses more than one GC-4622 module, the
secondGC-4622 needs to be defined from "Q4.0", because each 4622 has 2
channels; "%" (percent sign) is the direct variable start character: ":"
(semicolon) is the variable or type separator. Use the symbol variable AO to

Guangcheng Technology GC-4622 user manual
write the signed integer from the %Q0.0 address. AT stands for the address of
variable access and the additional attributes of the variable (see page 46 of the
e-book for details).
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 channel 1 of the first
GC-4622 module to output +5V, and the output of other channels are all 0V,
you need to write CAN to GCAN-IO-8000 module The data frame ID is 0x201,
the data length (DLC) is 8, and the frame data is 0xFF, 0x3F, 0x00, 0x00, 0x00,
0x00, 0x00, 0x00 data.
