Note: The catalog confirms the number of input channels, sensor type, temperature measurement range, wiring configuration, resolution, accuracy, and response time, but does not specify details about open sensor detection, electrical isolation, or dimensions. Therefore, it is recommended to check the specific model datasheet before system design.

RTD Input 4 Channels

The PLC EXPLX3V-4PT supports 4 RTD sensors of type PT100 for receiving temperature data from various locations within machinery or production processes.

The 4-channel input allows the installation of multiple temperature sensors at different positions and feeding this data into the PLC system for processing, display, or use in control logic.

Supports PT100 Sensors

The EXPLX3V-4PT supports RTD type PT100 sensors according to catalog information, which are temperature sensors that rely on changes in platinum resistance with temperature.

Generally, a PT100 has a standard resistance value of 100 Ohm at 0°C and is commonly used for temperature measurement in industrial systems.

The selection should check the sensor type, standard resistance values, and wiring compatibility with the module.

Suitable for 2-Wire and 3-Wire Sensor Connections

The module supports RTD sensor connections of both 2-Wire and 3-Wire types as per the catalog data.

2-Wire Connection: Uses two signal wires to connect with a PT100 sensor, where the resistance of the wire may affect the reading, especially over long distances.

3-Wire Connection: This type can compensate for the impact of wire resistance under appropriate conditions by connecting according to the manufacturer's wiring diagram.

Before installation, it is necessary to check terminal numbers and channel settings to ensure accurate temperature readings.

Temperature Measurement Range -100 to +600°C

The EXPLX3V-4PT supports a temperature measurement range of -100 to +600°C or -148 to +1112°F as per the catalog data.

This measurement range is the capability of the module, and the PT100 sensors used must have appropriate temperature scale and construction for the actual environment.

The selection of a sensor should consider the probe's measuring range, sensor housing material, heat resistance, and installation characteristics as well.

Input Response Time 15 ms / 4 Channels

The catalog specifies an input signal response time of 15 ms for 4 channels, which is used to evaluate the module’s signal reading speed.

The module's Response Time value does not refer to the PT100 sensor's thermal response time, which depends on the sensor structure, installation method, and measurement environment.

Resolution 12 bit (12-bit Resolution)

The module has a signal reading resolution of 12 bits as per catalog data for converting measured data into digital values for processing in PLC systems.

A 12-bit resolution does not directly mean the accuracy of measurement, as actual measurement results depend on the module, sensor, wiring, and installation.

Accuracy ±1% Full Scale

The EXPLX3V-4PT has an accuracy of ±1% full scale according to catalog data.

To consider errors for high-precision temperature control applications, one should review the datasheet and account for PT100 sensor inaccuracies as well as signal wire impact.

24 VDC ±10% Power Supply System

The module uses a 24 VDC ±10% power supply and has a working current of 55 mA, according to the catalog data.

The design of the power supply system should consider the electrical load in conjunction with other modules within the PLC system and verify the power supply wiring method as per the manufacturer's manual.

Compatibility with PLC Systems

EXPLX3V-4PT is an RTD module for expanding temperature measurement points for PLC systems that support it. Compatibility with CPU and expansion module requirements must be verified before installation.

The sensor configuration, wiring, and temperature display in the control program should be checked to ensure system requirements are met.
