SELEC TEMPERATURE CONTROLLER TC244

SELEC TEMPERATURE CONTROLLER TC244 – High-Precision Dual-Display Process Controller

The SELEC TEMPERATURE CONTROLLER TC244 (often ordered as the TC244AX series) is a versatile 72 mm × 72 mm panel-mount temperature controller engineered for industrial thermal automation. Featuring a dual 4-digit, 7-segment LED display, this controller provides real-time visibility of both the Process Value (PV in bright red) and Setpoint Value (SV in clear green) simultaneously.

Designed to accommodate universal sensor inputs—including standard Thermocouples (J, K, T, R, S) and RTD sensors (Pt100)—the SELEC TEMPERATURE CONTROLLER TC244 supports both ON-OFF and auto-tuning PID control algorithms. Its dual setpoint output capability (main control output plus auxiliary alarm/relay) makes it an ideal solution for precise temperature regulation in packaging, plastics processing, heat treatment furnaces, and environmental chambers.

As illustrated in the product image, the front panel features a rugged bezel with three capacitive tactile buttons for swift parameter configuration and setpoint adjustments.

Key Features of the SELEC TEMPERATURE CONTROLLER TC244

• Dual 4-Digit LED Display: Simultaneously displays the live Process Value (PV) and programmed Setpoint Value (SV) for effortless monitoring.

• Universal Sensor Input Compatibility: Accepts various input sensors including J, K, T, R, and S thermocouples as well as 3-wire Pt100 RTD sensors.

• Selectable Control Algorithms: Supports high-precision Auto-Tuning PID control for tight thermal stability, or ON-OFF mode with configurable hysteresis for simple heating/cooling circuits.

• Field-Selectable Control Outputs: Features field-selectable main control outputs via a 5 A electromechanical relay or 12V DC Solid State Relay (SSR) pulse drive, plus an auxiliary relay output for alarms or cooling control.

• Advanced Process Functions: Includes Heat-Cool PID control options, built-in Dwell Timer mode (1 to 9999 min), and°C/°F unit selectability.

• IP65 Front Panel Protection: Sealed faceplate design protects internal electronics against splash water, oil spray, and dust buildup in demanding factory environments.

Common Applications and Industrial Usage

The flexible input range and dual-output configuration of the SELEC TEMPERATURE CONTROLLER TC244 make it a preferred control device across various manufacturing and process industries:

• Plastics & Injection Molding: Controls barrel heater bands, nozzle temperatures, and hot runner systems to ensure consistent melt quality.

• Packaging Machines: Regulates heat-sealing jaws, shrink tunnels, and blenders in high-speed wrapping lines.

• Industrial Ovens & Furnaces: Manages thermal profiles in heat treatment, powder coating, and curing ovens using PID auto-tuning to prevent temperature overshoot.

• Food & Beverage Processing: Maintains strict thermal boundaries in pasteurization equipment, baking ovens, and commercial fryers.

Operating Guidelines and Best Practices

INSTALLATION TIP: Ensure proper sensor wire shielding to prevent high-frequency interference from neighboring motor drives and inductive heaters.

• Auto-Tuning Execution: Run the controller’s Auto-Tune cycle upon initial setup at full system load to let the algorithm automatically compute optimal Proportional (P), Integral (I), and Derivative (D) parameters.

• SSR Output Connection: When switching high-duty heaters, set the main output to SSR mode and drive an
  external Solid State Relay to extend control lifetime and eliminate mechanical contact chatter.
