Expand the capabilities of the EQSP32 micro-PLC with high-precision industrial temperature monitoring using thermocouples.
The EQXTC06 is a DIN-rail mountable expansion module designed for K-type thermocouples, offering six channels for precise and reliable temperature measurements. With automatic detection, it seamlessly integrates with EQSP32, providing real-time temperature data for industrial automation and process control.
Designed for flexibility and accuracy, the module incorporates cold-junction compensation, fault detection (for open, shorted, or miswired thermocouples), and a high-resolution 14-bit signed conversion providing a nominal temperature resolution of 0.25°C. Its compact DIN-rail enclosure ensures easy installation, allowing for organized and scalable automation solutions.
With support for up to 15 EQXTC06 modules, EQSP32 IIoT PLC can manage up to 90 thermocouple sensors, making it a powerful solution for large-scale temperature monitoring applications.
Key Features of EQXTC:
- 6 Thermocouple Inputs: Supports sequential measurements on six K-type thermocouples.
- High-Resolution Measurement: 14-bit signed temperature readings with 0.25°C resolution.
- Integrated Cold-Junction Compensation: Automatically adjusts temperature readings based on the ambient temperature for improved accuracy.
- Fault Detection: Detects thermocouple shorts to GND or VCC and open thermocouples.
- ESD Protection: All pins protected up to ±2kV (Human Body Model), ensuring durability in electrostatic-prone environments.
- Expandability: Add more expansion modules as needed to extend functionality.
- Automatic Detection: EQXTC06 is automatically detected by EQSP32 upon power-up for a plug-and-play experience.
- Seamless Integration: Programming and integration simplified through the provided library API and the EQ-AI code generation assistant.
- DIN-Rail Mountable: Compact design for seamless and organized installation in standard DIN-rail control cabinets.
- Visual Indicators: Provides clear status for power and module status.
- Connection: After mounting the module on the DIN-rail, simply slide it to connect with EQSP32 via the board-to-board connector.
- Powered by EQSP32: No external power supply required, simplifying setup.
- Field-Upgradable Firmware: Easy firmware updates, can be applied via the front-facing USB-C port.
- Industrial-Grade Design: Operating temperature range -20°C to 55°C, suitable for harsh environments.
