Given the previous focus on the core challenges of real-time data acquisition from hot runner sensors, such as strong electromagnetic interference, high temperatures, and multi-node synchronization, the following are recommendations for mainstream data acquisition modules suitable for different scenarios:
Phoenix RTD Thermometer Acquisition Module: Designed specifically for high-temperature industrial environments, featuring opto-isolation for interference suppression. Compatible with hot runner thermocouples/PT100 sensors, achieving an acquisition accuracy of up to 0.1℃, it is a mainstream choice in the injection molding industry.
Schneider Modbus-RTU Acquisition Module: Supports multi-node synchronous acquisition. A single module can connect to 16 sensors, directly interfaced with hot runner temperature control systems without additional conversion, suitable for small to medium-scale multi-loop hot runner systems.
Siemens Profinet High-Speed Acquisition Module: Supports millisecond-level real-time data upload, compatible with large hot runner clusters of 32 or more channels, and can directly interface with host computer MES systems for remote monitoring.
The domestically produced Delta DVP series data acquisition modules offer excellent cost-effectiveness, with a temperature range of -20℃ to 85℃, making them fully compatible with the high-temperature operating conditions of hot runner control cabinets and suitable for conventional injection molding scenarios with limited budgets.
These modules specifically address the pain points of strong interference and high temperatures in hot runner scenarios, allowing for selection based on specific needs.
