Note: The catalog confirms the number of inputs, signal type, input current, response time, and Photo-Coupling circuitry but does not specify physical dimensions, module power supply specifications, or a complete list of compatible PLC models. Therefore, these details must be verified from the product manual before designing the system.
8 Digital Inputs
The PLC EXPLX3V-8EX supports 8 digital signal inputs for monitoring external device status and sending data to supported PLC systems.
Increasing the number of input channels allows for expanding signal reception from sensors or switches in machinery as needed, but module quantity limitations and compatibility with the main PLC must be checked before installation.
Supports PNP and NPN Signals
The module supports both PNP and NPN digital input signals at 24 VDC according to catalog information.
PNP Input: This is signal reception from devices that switch the positive voltage to the input channel as per the specified wiring configuration.
NPN Input: This is signal reception from devices that switch down to ground as per the specified wiring configuration.
Selecting PNP or NPN must be done according to the Wiring Diagram of model EXPLX3V-8EX to prevent incorrect wiring and abnormal operation.
24 VDC Input Signal Level
The EXPLX3V-8EX supports input signals at 24 VDC, with the catalog specifying an input current of 5 mA at DC 24 V.
To design a circuit, you should check the acceptable voltage range, ON/OFF voltage levels, and wiring requirements from the manufacturer's datasheet before connecting the device.
Input Response Time 10 ms
The module has an input signal response time of 10 ms as per the catalog data. It is suitable for general status signal reception considerations in industrial control systems.
When applying it, consider the width of the input signal and the PLC processing cycle together to ensure that the system can detect the status as required.
For high-speed pulse counting or signals with short durations, you should check the suitability of specialized modules since the catalog does not specify a High-Speed Counter function for EXPLX3V-8EX.
Photo-Coupling Input Circuit
The EXPLX3V-8EX uses a photo-coupling signal receiving circuit as per the catalog data, utilizing the principle of light signal transmission within an electronic circuit.
This type of circuit design can be used to connect signals between circuit sections according to the manufacturer's structure. However, details about circuit separation and insulation voltage ratings must be checked directly from the datasheet.
Connecting with Sensors and Switches
The module can be applied to receive signals from devices with PNP or NPN digital output types that have suitable electrical specifications, such as position detectors or status check switches.
Examples of equipment that can be considered for use together include Proximity Sensor, Photoelectric Sensor, and Limit Switch. You must verify the contact type or output circuitry of the device before connecting it.
