Description: The SPS200 is an industrial controller designed for automated management of chemical processes. It interfaces with chemical injection systems, providing real-time monitoring and adjustment capabilities.

Core Specifications:

• Dimensional Outline: Compact form factor measuring 150 x 150 x 91 mm, designed for integration into various industrial settings.

• Display and Interface: Equipped with a clear, backlit LCD and tactile push-buttons for on-site programming and status checks.

• Power Requirements: +12V power input, ensuring compatibility with standard industrial power supplies.

Connectivity and Communication:

• Sensor Inputs: Accepts analog inputs from two channels (AI1, AI2) and one digital input (DI1), facilitating connection with tank level sensors, flowmeters, and pressure or temperature sensors.

• Communication Protocol: Features RS485 Modbus Slave communication, allowing for seamless integration with customer SCADA systems for remote monitoring and control.

Functional Capabilities:

• Variable Speed Control: Specifically designed to regulate brushed motor speeds, with a local speed dial or remote 0-5V control options. This feature is coupled with the ability to toggle motors on/off or adjust for low injection rates.

• Solar Pump Management: Incorporates functionality for solar pump operation with on/off and variable speed controls, maximizing energy efficiency.

• Pump Monitoring: Monitors pump power with continuous amps/volts display, including programmable high amps and low volts shutoff for enhanced safety and equipment protection.

Process Control Features:

• Scavenger Control: Customizable injection rate modulation based on multiple parameters such as production flow rate and target ppm.

• Tank Level Monitoring: Uses depth from analog output sensor readings, with options for ultrasonic, radar, and other measurement techniques. Includes features for low level pump cut-off to prevent dry running.

• pH (Refinery) Control: Automates pH adjustments to achieve target levels, vital for process consistency and product quality.

• Batch Control: Manages batching volume and period with precision, adaptable from 1 minute to 45 days to fit operational cycles.

• Methanol (Temperature) Control: Enables on/off control and adjusts injection rates according to a predefined temperature table.

Support for Various Pump Types:

• Solar Pumps: On/Off and variable speed control.

• Pneumatic Pumps: Solenoid control via external flowmeter input.

• Electric Pumps: Operation through 0-5V or 4-20mA control signals.

Diverse Applications: The SPS200 is ideally suited for use in chemical processing environments where accurate dosing and chemical application are critical. Its robust design and versatile control options make it an essential component in water treatment facilities, oil refineries, and any industrial application where chemical automation is required.
