Note: The catalog confirms the number of input channels, signal type, voltage level, input current, response time, and Photo-Coupling circuit, but does not specify the module dimensions or complete power supply details. Therefore, it is advisable to check the specific model Datasheet before system design.
Digital Input 16 Channels
The PLC EXPLX3V-16EX supports digital inputs of 16 points for receiving status signals from external devices into a compatible PLC system.
It can be applied to detect workpiece positions, check machine statuses, and read signals from multiple sensors within the production line. Compatibility with signal types and voltage ratings must be considered.
Suitable for PNP and NPN Signals
The module supports both PNP and NPN input signals at 24 VDC according to the catalog information.
PNP: This is a positive switching signal type where the sensor sends positive voltage to the input channel when activated as per the specified wiring configuration.
NPN: This is a ground switching signal type where the sensor pulls the signal down to ground when activated as per the specified wiring configuration.
The use of PNP or NPN signals requires checking the common terminal and wiring diagram of the module. It should not be assumed that both types can be mixed on all channels simultaneously without limitations.
Input Voltage Level 24 VDC
The EXPLX3V-16EX uses an input signal level of 24 VDC with a voltage tolerance of ±10% as per the catalog.
The specified input current is 5 mA at 24 VDC. System design must verify the ON/OFF status voltage range and source device capabilities from additional Datasheet information.
Input Response Time 10 ms
The module has an input response time of 10 ms for considering suitability in detecting digital signals.
In system design, the pulse width, sensor response time, and PLC processing cycle must be taken into account to ensure that the system can detect status as required.
If it is high-speed pulse counting or reading Encoder signals, you should check modules specifically designed for High-Speed Counter because the catalog does not confirm such functions for EXPLX3V-16EX.
Photo-Coupling Input Circuit
The EXPLX3V-16EX uses a Photo-Coupling circuit as per the catalog, which is a technique of signal transmission using light within an electronic device.
To check electrical isolation and voltage test insulation coordinates, refer to the manufacturer's Datasheet since the catalog does not specify such details.
Usage with Sensors and Detection Devices
The module can be applied to receive signals from PNP or NPN type sensors that match the device specifications, such as Proximity Sensor, Photoelectric Sensor, Limit Switch, and status signals from control circuits.
Wiring must be checked for switching patterns, voltage, current, and correct common terminal connections before actual use.
Examples of Application (Applications)
- Sensor signal reception system in automatic machinery
- System to detect workpiece position on production lines
- Limit Switch and Proximity Sensor status reading system
- Machinery operation status monitoring system
- Digital Input expansion system for supported PLCs
- Factory Automation and Machine Control systems
- Equipment status checking system within the factory
- Design and development of industrial control systems
Comparison between EXPLX3V-8EX and EXPLX3V-16EX
| Specifications |
EXPLX3V-8EX |
EXPLX3V-16EX |
| Digital Inputs | 8 Channels | 16 Channels |
| Input Type | PNP / NPN | PNP / NPN |
| Nominal Input Voltage | 24 VDC | 24 VDC |
| Input Current | 5 mA at 24 VDC | 5 mA at 24 VDC |
| Response Time | 10 ms | 10 ms |
| Input Circuit | Photo-Coupling | Photo-Coupling |
Both models have input characteristics similar to those specified in the catalog, but differ in the number of Digital Input channels. The EXPLX3V-16EX supports 16 channels, while the EXPLX3V-8EX supports 8 channels.
