Note: The catalog confirms the number of input channels, signal range for voltage and current, resolution, response time, accuracy, and module power supply information, but does not specify Input Impedance, isolation details, dimensions, or supported PLC models completely. Therefore, it is recommended to check the specific model datasheet before system design.

4 Analog Inputs

The SCMA EXPLX3V-4AD supports 4 analog signal inputs for connecting with measuring and signaling devices that have outputs compatible with standard signal ranges supported by the module.

This can be applied to receive data from multiple measurement points in a production process, but each channel configuration must be checked according to the manufacturer's manual.

Supports Voltage Signal -10 V to +10 V

The module supports analog voltage signals within the range of -10 V to +10 V as per catalog information. It is suitable for connecting devices that send bipolar voltage signals.

Before use, it is necessary to check signal terminals, reference voltages, and maximum acceptable voltage levels from the manufacturer's wiring diagram.

Supports Current Signal 4-20 mA

EXPLX3V-4AD supports the standard analog current signal of 4-20 mA, commonly used in industrial process measurement and control systems.

It can be applied to devices with a 4-20 mA output such as Pressure Transmitter, Flow Transmitter or Temperature Transmitter that are electrically compatible.

The selection must check whether the source device is Active or Passive type, as well as the power supply configuration of the Current Loop before connecting to the module.

Normal Speed and High Speed Modes

Operating Mode	Response Time
Normal Speed	15 ms/channel
High Speed	6 ms/channel

The module has two response time modes for input consideration as per the catalog data, which can be selected based on signal characteristics and measurement process capabilities of the system.

Further details about mode configuration and impact on accuracy or signal filtering should be reviewed from the manufacturer's manual.

12-bit Resolution

The EXPLX3V-4AD has a 12-bit resolution for analog signal conversion, used to convert signals from external devices into digital values for processing in PLC systems.

A 12-bit resolution does not imply measurement accuracy as actual accuracy still depends on the circuitry of the signal converter, installation conditions and characteristics of connected measuring equipment.

Accuracy ±1%

The catalog specifies an accuracy of ±1% for signals ranging from -10 V to +10 V voltage and 4-20 mA current.

Detailed calculation basis and testing conditions for accuracy must be reviewed from the Datasheet before use in applications with specific precision requirements.

Power Supply 24 VDC ±10%

The module uses a power supply of 24 VDC ±10% and specifies an operating current of 55 mA for control cabinet power system design.

Sufficient power allowance should be considered for other devices in the system, along with checking the power supply configuration and circuit protection requirements as per the manufacturer's manual.

Usage with PLC Systems

The EXPLX3V-4AD is an Analog Input module to expand the number of signal channels supported by PLC systems. Before installation, compatibility must be checked for the main CPU model, maximum connected modules and channel configuration methods.

The name EXPLX3V Series should not be used to confirm compatibility with all CPU models without a manual.
