Description

The SN-300WQC-DC-PH/ORP-N01-201T is a dedicated industrial controller that provides precise measurement and control of pH and ORP levels in process fluids. It employs high-accuracy sensing with automatic temperature compensation (ATC) to ensure stable readings across varying environmental conditions. The controller is engineered for harsh industrial settings with an anti-interference design and opto-isolated outputs.

Featuring a high-brightness LCD, it displays real-time pH/ORP values, temperature, and system status. The integrated RS485 Modbus interface allows for seamless networking and remote configuration, making it suitable for centralized monitoring in water treatment plants, chemical processing, and power generation facilities.

Key Features

  • Dual-channel monitoring for pH (0.00-14.00 pH) and ORP (±1999 mV) with high accuracy.
  • Automatic Temperature Compensation (ATC) using an integrated PT1000 temperature sensor for measurement stability.
  • Opto-isolated 4-20mA current loop output ensures signal integrity and protects against ground loops.
  • RS485 Modbus RTU protocol enables multi-drop communication and integration with PLCs, DCS, and SCADA.
  • Programmable flushing relay output for scheduling automatic electrode cleaning cycles.
  • Built-in real-time clock and data logging function stores historical measurement data.
  • Rugged IP65-rated (inferred) enclosure designed for panel mounting in industrial control cabinets.
  • Wide operating voltage range of 24V DC for compatibility with standard industrial power supplies.

Applications

  • Continuous pH/ORP monitoring and control in industrial wastewater treatment plants.
  • Process chemistry control in chemical manufacturing and pharmaceutical production.
  • Cooling water and boiler feedwater quality management in power generation facilities.
  • Effluent monitoring and environmental compliance reporting.
  • Swimming pool and aquaculture water quality automation.

Frequently Asked Questions

What is the power supply requirement for this pH/ORP controller?

The controller operates on a 24V DC power supply, which is standard for industrial control panels and PLC systems. Ensure your power source can provide stable 24V DC within the specified current capacity for the unit and any connected peripherals like cleaning pumps.

How do I communicate with this controller for remote monitoring?

The unit features an RS485 interface using the Modbus RTU protocol. You can connect it to a PLC, SCADA system, or data acquisition module using a standard RS485 cable. Configure the device's unique Modbus address via its front-panel interface to enable multi-drop network communication.

What is the purpose of the flushing relay output?

The programmable relay output is designed to control an external solenoid valve or pump for automated electrode cleaning. You can set timed cleaning cycles from the controller's menu to periodically rinse the pH or ORP electrode, which is critical for maintaining long-term measurement accuracy in fouling applications like wastewater.
