Vhandy Technology 1. Function introduction 1.1 Functional Overview The GC-3822 module is an I/O module with integrated 2 temperature sensor (PT100) input channels. The module can be used to collect temperature information in real time and send the collected values to the GCAN-PLC400/510 series controller or GCAN-8000/8100 series coupler via the internal bus. This module can be used with any other GC series IO module to realize the collection and processing of temperature analog data in industrial automation or distributed control systems. 1.2 Performance characteristics ● The number of...

Vhandy Technology 2. Equipment installation and use This chapter will explain in detail the installation method, wiring method, the meaning of indicator light and the meaning of interface of GC-3822 module. 2.1 Module fixing The installation method of the GC-3822 module is shown in Figure 2.1. You need to use a flat-blade screwdriver for auxiliary installation. Figure 2.1 GC-3822 module installation First, you need to install the fieldbus coupler on the rail, and then attach the GC-3822 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-3822 module installation Figure 2.3 GC-3822 module terminal block The terminal block of GC-3822 module is shown in Figure 2.3. The GC-3822 contains 2 sets of inputs and can connect up to 2 PT100 sensors. The serial numbers corresponding to the terminals and their meanings are shown in Table2.1.

The specific indication function of the indicator light is shown in Table 2.2. When the indicator is on, the GC-3822 module status...

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-3822 module, the second GC-3822 needs to be defined from "I4.0", because each 3822 has 2 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...
