Advanced Monitoring and Control

This controller offers dual setpoints for independent relay operation, supporting sophisticated process management. Its two SPDT relays handle up to 5A at 230VAC, making it suitable for complex automation and fail-safe applications. The large, easy-to-read LCD display ensures operators can quickly assess system status and respond as needed.

Versatile Integration and Compatibility

Equipped with an isolated 4-20 mA transmitter output, the device can interface smoothly with most monitoring and control systems. The BNC input supports standard ORP electrodes, and terminal blocks make wiring straightforward. Compact panel-mount design (96 x 96 x 110 mm) fits seamlessly into control panels.

Durable Construction for Demanding Environments

Housed in robust ABS plastic, this controller withstands pressures up to 6 bar and temperatures from 0C to 50C. Automatic or manual temperature compensation (optional) ensures stable, accurate readings, with accuracy up to 2 mV, ideal for industrial and laboratory settings.

FAQs of Dual Limits ORP Controller with Iso 4 20mA Tx Outp:

Q: How is the Dual Limits ORP Controller installed and connected?

A: The controller is designed for easy panel mounting with a compact 96 x 96 x 110 mm footprint. Its BNC connector allows quick connection to standard ORP electrodes, while terminal blocks simplify wiring for relay outputs and the isolated 4-20 mA transmitter.

Q: What are the main functions and benefits of having dual setpoints?

A: Dual setpoints enable independent relay control, providing flexible options for automationsuch as activating alarms, dosing pumps, or safety shutdowns. This enhances process reliability and allows precise management of oxidation-reduction potential within a desired range.

Q: When should temperature compensation be used, and how does it work?

A: Temperature compensation is important when ORP readings may be affected by temperature fluctuations. This model offers both automatic and manual compensation (optional), ensuring that readings remain accurate despite environmental changes, thereby optimizing process control.

Q: Where is the Dual Limits ORP Controller typically used?

A: This controller is commonly deployed in water treatment plants, industrial processing, chemical manufacturing, and laboratory environmentsanywhere precise ORP monitoring and dual-action control are required for safety or process efficiency.

Q: What safety features are included with this ORP controller?

A: Safety is enhanced by two independent SPDT relays rated at 5A/230VAC, which can be used to trigger alarms, shutdown systems, or actuate other safety devices. The isolated 4-20 mA output minimizes interference and ensures stable data transmission.

Q: How does the controller connect with external monitoring systems?

A: The instrument provides an isolated 4-20 mA output, compatible with SCADA, PLC, or data loggers. This isolation helps protect connected equipment and maintains signal integrity during process communication.
