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

Thermocouple Input 4 Channels

The PLC EXPLX3V-4TC supports connecting thermocouples at four points for collecting temperature data from various locations within machinery and production processes.

Data read can be imported into compatible PLCs to display, monitor temperatures, or process according to control programs. Compatibility with the main CPU model must be verified before installation.

Supports Thermocouple Type K

The EXPLX3V-4TC supports thermocouples of type K, which are widely used temperature sensors in various industrial applications.

The specified measurement range for Type K is -100 to +1200°C or -148 to +2192°F, suitable for considering temperature monitoring in high-temperature processes. The appropriate sensor and probe with the correct temperature rating must be selected.

Supports Thermocouple Type J

The module supports Thermocouple Type J as per the catalog data, with a measurement range of -100 to +600°C or -148 to +1112°F.

The correct type of thermocouple must be checked and connected according to system control settings for accurate temperature signal conversion.

Comparison of Thermocouple Type K and J Measurement Ranges

Thermocouple Type	Temperature Range (°C)	Temperature Range (°F)
Type K	-100 to +1200°C	-148 to +2192°F
Type J	-100 to +600°C	-148 to +1112°F

The measurement range mentioned is the module capability as per the catalog, while the actual temperature range that can be used depends on the type of wire, material, and structure of the selected thermocouple probe.

Input Response Time 240 ms / 4 Channels

The catalog specifies an input signal response time of 240 ms for 4 channels to consider the speed of data reading from the thermocouple sensor.

This value is the electronic response time of the module and not the thermal response time of the probe, which depends on the material, size, and installation method of the sensor.

Resolution 12 bit (12-bit Resolution)

The EXPLX3V-4TC has a resolution of 12 bits for converting thermocouple sensor data to digital values for processing in the PLC system.

A 12-bit resolution should not be interpreted as direct measurement accuracy, since actual measurements depend on signal reading circuits, sensors, and installation conditions.

Accuracy ±0.5% Full Scale

The module has an accuracy of ±0.5% full scale according to the catalog data, which is information for considering module deviation.

For high-precision temperature control applications, sensor thermocouple line, connector, and compensation temperature conditions should also be evaluated for error.

Powder Supply 24 VDC ±10%

The EXPLX3V-4TC operates on a power supply module of 24 VDC ±10% and has a working current of 55 mA as per the catalog data.

The system design should verify the power source and wiring according to the manufacturer's specifications, considering its use alongside other modules within the PLC system.

Compatibility with PLC System

The EXPLX3V-4TC is a Thermocouple Input module for expanding temperature measurement points in PLC systems that support it. Compatibility checks must be performed with CPU and Expansion Module before installation.

It's important to verify sensor type settings, thermocouple wiring connections, and temperature display within the control program to ensure proper operation for production processes.
