Frequently Asked Questions

What sensors are compatible with the Rex C900?

The Rex C900 supports a wide range of temperature sensors, including thermocouples (types K, J, E, T, B, S, N) and PT100 RTDs. The sensor type is selectable via a simple configuration menu, allowing easy adaptation to your existing setup. The controller automatically calibrates the input to provide accurate readings. For RTD inputs, it uses a three-wire connection to eliminate lead resistance errors. If you require other sensor types, contact us for customization options.
The Rex C900 has an auto-tuning function that automatically determines the optimal PID constants for your specific process. To use it, go to the tuning menu, select 'AT', and press Enter. The controller will perform a series of control actions and then set the PID parameters. For processes with variable dynamics, manual tuning is also possible. We provide detailed instructions in the user manual, and our technical support team is available to guide you through the process.
Yes, the Rex C900 supports two outputs, which can be configured for heating and cooling separately. For example, output 1 (heating) can be a relay for a heater, and output 2 (cooling) can be an SSR drive for a refrigeration unit. The controller uses separate PID parameters for heating and cooling to handle the different thermal response times. This makes it ideal for applications such as extruders where temperature must be tightly regulated in both directions.
Yes, the Rex C900 offers an optional RS485 communication interface using Modbus RTU protocol. This allows the controller to be connected to a PLC, HMI, or PC for real-time data monitoring and remote configuration. With multiple controllers on the same bus, you can create a networked control system. The communication parameters (baud rate, parity, address) are user-configurable. This feature is particularly useful for industrial automation and quality control applications where data tracking is essential.
We offer a 2-year warranty on the Rex C900 Temperature Controller. During the warranty period, any defects in materials or workmanship are repaired or replaced free of charge. Our after-sales support includes a 24-hour online service, telephone consultations, and email support. We provide detailed user manuals, installation guides, and video tutorials. If you experience any issues, our trained technicians will assist with troubleshooting and provide replacement parts promptly. This commitment to support ensures that you can rely on our products for long-term performance.
