Frequently Asked Questions

What types of sensors are compatible with the CHB402 temperature controller?

The CHB402 temperature controller is designed to work with a variety of temperature sensors, including thermocouples (types K, J, E, T) and platinum RTDs (PT100). It also accepts analog inputs such as 4-20mA and 0-10V from transmitters. When configuring the controller, you can select the appropriate sensor type from the menu, and it will automatically calibrate to provide accurate readings. For thermocouple inputs, the controller features cold-junction compensation to ensure precision across a wide temperature range. Whether you are using a standard probe or a custom sensor, the CHB402 offers flexibility to meet your application needs.
Absolutely. The CHB402 temperature controller can be configured for heating or cooling control using the direct/reverse action setting. In heating mode, the output activates when the process temperature is below the setpoint; in cooling, it activates when above. This makes it suitable for applications such as ovens, furnaces, and also chillers or refrigeration systems. The controller also supports optional alarm functions for high/low temperature limits, aiding in process safety.
Yes, it is designed for easy installation. The controller has a standard 1/16 DIN form factor (48x48mm) and can be panel-mounted quickly using the provided clip. The wiring uses screw terminals clearly labeled for power, sensor, and output connections. The user manual provides detailed wiring diagrams and setup instructions, making installation straightforward for technicians. For more complex systems, our technical support team is available to assist.
Yes, the CHB402 offers an optional RS485 communication interface using Modbus RTU protocol. This allows the controller to be integrated into a networked system for remote monitoring and control via a PLC or PC. With RS485, multiple controllers can be connected on a single bus using a standard two-wire connection, enabling centralized data logging and process supervision. This feature is particularly beneficial for complex industrial processes where centralized control is required.
The CHB402 is equipped with relay output (SPDT, 3A/250VAC) as standard, which is ideal for driving contactors, solenoid valves, or small heaters. Additionally, it can be configured with an SSR driver output (DC pulse) to control solid state relays, allowing faster and silent switching for applications requiring high cycling rates. Some models also offer a second relay for alarm outputs or additional control functionality. You can choose the output configuration that matches your application requirements during ordering.

We upgraded our plastic extrusion line with the CHB402 temperature controller, and the improvement in temperature consistency is remarkable. The self-tuning algorithm quickly optimized settings, and we now maintain ±0.5°C control, which has significantly reduced scrap rates. The dual display is clear and easy to read, and the optional RS485 allows us to monitor all zones from a central PC. The controller has been running 24/7 for six months without a single issue. Highly recommended for any industrial application requiring precision control.
