Supplier's note

1. Technical Breakthroughs:

   • Relay Output Integration: The 1-4 channel expansion allows direct control of industrial actuators, reducing the need for external controllers.
   • Wide Voltage Input (DC 9-36V): Eliminates power conversion costs in variable industrial settings.
   • CE Compliance: Ensures safe deployment in EU-standard facilities.

2. Version Selection Guide:

   • Base Model: Ideal for small-scale automation (e.g., HVAC systems) requiring basic Modbus connectivity.
   • Advanced Model: Suitable for mid-sized factories needing MQTT for cloud IoT platforms and dual relay control.
   • Pro Model: Best for critical infrastructure (e.g., power grids) demanding enterprise-grade security (TLS 1.3) and multi-protocol support.

With the ZHC1931’s Modbus-to-MQTT gateway capability, you can modernize legacy systems without downtime. Its 20% faster RS485 polling rate than industry benchmarks ensures real-time data for time-sensitive processes. For high-security applications, the Pro Model’s hardware-based TPM encryption safeguards industrial networks against cyber threats.
