1. Introduction 1.1 Overview The GC-3674 module has integrated 4 analog input 0V~+10V channels, which acquires analog signals in real time and transmits them to the GCANPLC coupler. This module can be used with any other GC Series IO module to capture and process analog data in industrial automation or distributed control systems. 1.2 Properties at a glance ● 4 input channels ● Acquisition voltage range:0V~+10V ● Internal resistance: 100kΩ ● Signal form: differential signal ● Resolution: 16bits ● Conversion time:<300ms ● Electric isolation:500Vrms ● Power Supply by GCAN-PLC-400...

2. Installation and use This chapter will describe the installation method, wiring method, meaning of the indicator and meaning of the interface of the GC-3674 module. 2.1 Module fixing The installation method of GC-3674 module as shown in Figure 2.1 and a flat-blade screwdriver is needed for auxiliary installation. Figure 2.1 Installation of GC-3674 module First the user need to install the GCAN-PLC on the guide rail and plug the GC-3674 along GCAN-PLC's right side until the lock is stuck. The GC-3674 module needs to be used with a GCAN-PLC-400 or GCAN8000/8100 series coupler, and can be...

2.3 System status indicator The GC-3674 module has 4 run indicators that 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 lit, the status of the GC-3674 module is shown in Table 2.3. Indicator Indication status RUN Green Operating Table 2.2 Indicator of GC-3674 module When the input signal of the GC-3674 module is connected normally and the current is more than 0, the running indicator will light up. Indicator Indication status Connection correct and Voltage value more than 0 RUN Connection...

necessary to define the variable type, input signal position, start character, separator, etc. For example: "AI0 AT%I0.0:INT;", where "0.0" represents the starting address of the first channel, each channel occupies 2 bytes, 0V~+10V corresponds to -65535, so the second The starting address of each channel is I2.0. When the user uses more than one GC-3674 module, the second GC-3674 needs to be defined from "I8.0", because each 3674 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...
