The Honeywell DC1040CR-302000-E is a microprocessor-based 1/4 DIN temperature controller from the DC1000 series, designed for precise and reliable regulation of temperature and other process variables in various industrial applications .
Key Features
-
Dual Display & Bargraph:Â Features two large 4-digit, 7-segment LED displays (red for Process Value/PV, green for Set Point/SP) for clear monitoring, along with a 10-LED bargraph that visually indicates the control output value (MV)Â .
-
Advanced Control Algorithms: Supports both PID (Proportional-Integral-Derivative) and ON/OFF control modes. It includes an advanced auto-tuning function that automatically calculates optimal PID values for your specific system, simplifying setup .
-
Flexible Input & Output: While the exact configuration should be verified, this model is known to support a wide range of inputs, including various thermocouples (e.g., K, J, R, S, B, E, N) and RTDs (e.g., PT100) . The “-302000-E” suffix in the model number typically indicates a specific output configuration, such as a 4-20mA linear output for control along with alarm relays .
-
Setpoint Programming:Â The controller can store and run programs, offering 2 programs with up to 8 segments each. These can be linked to function as a single 16-segment program, suitable for complex temperature profiles (ramp and soak)Â .
-
Alarm Capabilities:Â Equipped with up to 3 alarm outputs, which can be configured for 17 different event modes (e.g., high/low deviation, absolute high/low, system error)Â .
-
Communication: Optional RS232 or RS485 communication ports are available, supporting Modbus RTU and ASCII protocols for integration with supervisory systems .
-
User Interface & Security: A 4-digit security code (Function Lock) prevents unauthorized or accidental changes to parameters .
