Vhandy Technology 1. Function Introduction 1.1 Function Overview The GC-3844 module is an I/O module that integrates 4 input channels of temperature sensors (K-type thermocouples). This module can be used to collect temperature information in real time and send the collected values to GCAN-PLC-400 or GCAN-8000/8100 series couplers through the internal bus. This module can be used with any other GC series IO module to realize the acquisition and processing of analog data in industrial automation or distributed control systems. 1.2 Performance characteristics ● The number of input points is...

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-3844 module. 2.1 Module fixing The installation method of GC-3844 module is shown in Figure 2.1, you need to use a flat screwdriver for auxiliary installation. Figure 2.1 GC-3844 module installation First, you need to install the fieldbus coupler on the rail, and then attach the GC-3844 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-3844 module installation Figure 2.3 GC-3844 module terminal block The terminal block of GC-3844 module is shown in Figure 2.3. GC-3844 contains 4 sets of input points, and can connect up to 4 K-type thermocouples 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 GC3844 module status is shown in Table 2.3. Indicator light Indication status Red Error indication green Operating instructions Table 2.2 GC-3844 module indicator After the GC-3844 module is connected to the K-type...

Vhandy Technology 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-3844 module, the second GC-3844 needs to be defined from "I8.0", because each 3844 has 4 channels; "%" (percent sign) is the direct variable start symbol : ":" (semicolon) 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 variable (see...
