Frequently Asked Questions

What types of sensors can be used with the Rex C400?

The Rex C400 is compatible with a wide range of temperature sensors, including thermocouples K, E, J, T, S, and R, as well as PT100 RTDs. This flexibility ensures you can use the controller with various systems without needing additional converters. The sensor type can be easily configured via the front panel, and the controller automatically adjusts its linearization to suit the selected sensor, ensuring accurate readings across its entire range. For example, in a plastic injection molding machine, you might use a K-type thermocouple for temperatures up to 400°C, while in a low-temperature application, a PT100 might be preferred for its stability at sub-zero temperatures. The Rex C400's universal input eliminates the need for multiple controller models, simplifying inventory and reducing costs.
Yes, the Rex C400 is designed to handle both heating and cooling from a single unit. It features dual outputs: one can be configured for heating (relay or SSR) and the other for cooling (relay or SSR), allowing for closed-loop control in systems that require both functions. Additionally, it has a dead-band setting to prevent simultaneous activation of heating and cooling outputs, which saves energy and reduces wear on components. This makes the Rex C400 particularly useful in applications such as extruder barrel cooling or mold temperature control, where precise temperature maintenance is crucial for product quality. The controller's advanced logic ensures smooth transition between heating and cooling, avoiding overshoot and maintaining stable temperatures even under varying loads.
Absolutely. The Rex C400 has a standard 72x72mm panel-mount footprint, which is a common size for industrial controllers, making it a direct replacement for many existing controllers. It operates on universal power supplies (85-265VAC or 100-240VAC depending on model), allowing it to be integrated into diverse electrical systems. The controller's screw terminal connections are straightforward, making installation quick and straightforward. Furthermore, its comprehensive configuration options mean you can adjust it to match your specific process parameters without needing specialized expertise. We also provide detailed user manuals and wiring diagrams to assist with installation, and our technical support team is available to guide you through any challenges, ensuring a smooth transition to the Rex C400.
The Rex C400 offers an optional RS485 communication port that supports the Modbus RTU protocol. This enables easy integration with SCADA systems, PLCs, or PC-based monitoring software. With RS485, you can remotely monitor process variables, change setpoints, and acquire data for analysis, which is essential for modern industrial environments aiming for increased automation and data transparency. The controller also supports multiple device addressing, allowing multiple Rex C400 units to be connected on the same network. This is particularly beneficial for installations with multiple temperature control zones, such as ovens or multi-zone extruders, where centralized control and monitoring significantly enhance operational efficiency and reduce downtime.
The self-tuning function in the Rex C400 automatically calculates the optimal PID parameters for your specific system by analyzing the response to output variations. When first installed, or when process conditions change dramatically (e.g., new machine, different load), activating self-tuning can help achieve stable control with minimal overshoot and fast response. The controller performs a test sequence, briefly toggling the output to determine the thermal characteristics, then sets the P, I, and D values accordingly. This process typically takes a few minutes and should be performed when the system is at steady state. Once tuned, the controller retains these parameters in non-volatile memory, even during power loss. However, if your process has large variations in thermal load, periodic re-tuning might be beneficial. With our advanced algorithm, even without manual tuning, the Rex C400 performs well in most applications.
