BTC-905 1/16 DIN Digital Setting Temperature Controller

Precise DIP switch setting with relay or SSR output   

The BTC-905 is a compact 1/16 DIN digital temperature controller designed for applications that require stable control with a simple setup. It features a 3-digit DIP switch for direct setpoint configuration, eliminating the need for menu navigation. Compatible with J/K thermocouples and PT100 RTD sensors, the BTC-905 supports ON/OFF or time proportional control, with selectable relay, SSR, or analog output. Its robust housing, deviation alarm output, and universal 100–240VAC input make it ideal for OEM integration and space-constrained industrial systems.

Panel Display and Indicators

Clear red LED readout with status indicators  

The BTC-905 control panel is designed for simple and efficient monitoring of temperature status. It features a 3-1/2 digit, 0.4-inch red LED display, providing clear readout of process values. A red status LED indicates output activity, allowing users to instantly identify control status at a glance. The panel also includes a DIP switch setting interface, which is accessed internally for numeric setpoint configuration. Its compact layout supports DIN panel mounting, ideal for limited space environments.

Supports J/K thermocouples and PT100 RTD input

The BTC-905 supports universal sensor input for temperature monitoring and control. It is compatible with J-type and K-type thermocouples, as well as PT100 RTD sensors. This wide input compatibility allows the controller to be deployed in a variety of industrial heating or cooling systems. The input signal is processed with high stability to ensure accurate readings over time.

Selectable relay, SSR voltage, or analog output  

The BTC-905 offers flexible output configuration to match various control strategies. Users can select from relay contact output, voltage output for SSR drive (5V/30mA), or optional analog output for precise control. Output mode can be configured via jumper settings. The unit supports ON/OFF or time proportional control logic, making it adaptable to resistive or proportional heating applications
