Industrial Electronic Valve Control

Overview

Electronic valve control is essential to many applications across various industries for water treatment, chemical processing, oil, pharmaceuticals, and more for liquids and gases. This industrial electronic valve control system utilizes a flow sensor to monitor the delivery rate of any gas or liquid and control the flow via a motor-controlled valve. Flow status is displayed on an LCD and communicated over Ethernet or RS-485, meeting the Safety Integrity Level 2 (SIL2) standard through the Functional Safety Platform software.

System Benefits:

  • Supports the SIL2 standard with the Functional Safety Platform Software certified by TÜV.
  • Dual MCU system ensures safe operation and eliminates single points of failure.
  • Flexible system design operates on 12V or 24V.
  • RS-485 is fault-protected against 15kV ESD and over-voltages up to ±60V, with data rates up to 20Mbps, ensuring a safe and robust system.
