Vhandy Technology 1 Function Introduction 1.1 FunctionOverview The GC-3804 module is an I/O module with integrated 4-channel temperature sensor (PT100) input channel. The module can be used to collect temperature information in real time and send the collected values to the GCAN-PLC-400 or GCAN-8000/8100 series couplers via the internal bus. This module can be used with any other GC series IO module to achieve the collection and processing of analog data in industrial automation or distributed control systems. 1.2 Performance characteristics ● The number of input points is 4; ● The wiring...

Vhandy Technology 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 the GC-3804 module. 2.1 Module fixing The installation method of GC-3804 module is shown in Figure 2.1, you need to use a flat screwdriver for auxiliary installation. Figure 2.1 GC-3804 module installation First, you need to install the fieldbus coupler on the rail, and then attach the GC-3804 module to the right of the fieldbus coupler or other modules to add this component. As shown in Figure...

Vhandy Technology Figure 2.2 GC-3804 module installation Figure 2.3 GC-3804 module terminal block The terminal block of GC-3804 module is shown in Figure 2.3. GC-3804 contains 4 sets of input points, and can connect up to 4 PT100 sensors. The serial numbers corresponding to the terminals and their meanings are shown in Table 2.1.

The specific indication function of the indicator light is shown in Table 2.2. When the indicator is on, the GC3804 module status is shown in Table 2.3. Indicator light Indication status green Error indication green Operating instructions Table 2.2 GC-3804 module indicator After the GC-3804 module is connected to the PT100 normally, the...

Vhandy Technology start address of the first channel, each channel occupies 2 bytes, the collected temperature corresponds to -32768~+32767 so the second The starting address of the channel is I2.0. When the user uses more than one GC-3804 module, the second GC-3804 needs to be defined from "I8.0", because each 3804 has 4 channels; "%" (percent sign) is the direct variable start symbol : ":" (colon) is a variable or type separator. Use the symbol variable AI0 to read the signed integer from the %I0.0 address. AT stands for the address of variable access and the additional attributes of the...
