1. Introduction 1.1 Overview The GC-1502 module has integrated 2 counter digital input channels, which acquires digital 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 digital data in industrial automation or distributed control systems. 1.2 Properties at a glance ● 2 high speed input channels ● Input pulse voltage:5~30V ● Maximum input current:3mA ● Electrical isolation: 500 V(GC-bus) ● Current consumption:50mA ● 32-bitcounter ● No address setting, configuration via bus coupler or controller ●...

2. Installation This chapter will describe the installation method, wiring method, meaning of the indicator and meaning of the interface of the GC-1502 module. 2.1 Module fixing The installation method of GC-1502 module as shown in Figure 2.1 and a flat-blade screwdriver is needed for auxiliary installation. Figure 2.1 Installation of GC-1502 module First install the GCAN-PLC on the guide rail and plug the GC-1502 along GCAN-PLC's right side until the lock is stuck. When remove the GC-1502, the user need to release the self-locking mechanism by pulling out the orange label. The GC-1502...

Figure 2.2 Wiring method of GC-1502 module Figure 2.3 GC-1502 module terminal definition The wiring terminal block of GC-1502 module is shown in Figure 2.3. GC1502 contains 2 groups of pulse inputs, and can connect to 2 pulse signals at most. The corresponding serial numbers and definitions of each indicator are shown in Table 2.1

Channel1Fre AT % I8.0: UDINT; Channel2Fre AT % I12.0: UDINT; Gc-1502 has two counter channels, INPUT1 and GND1 for the first group, INPUT2 and GND2 for the second group. When the pins of RST1 and RST2 of gc-1502 are connected to the high current, the corresponding counter channel's count value and frequency can be cleared. 2.5 Combined with GCAN- 8000series The state of the digital input is represented by two byte For example: the GCAN-IO-8000 module node number is 1, the channel 1 of the first GC-1502 module count 28685, and the frequency is 56849Hz, then the CAN data frame ID sent by the...
