The Red Lion TCU is a temperature control unit designed to accept inputs from various temperature sensors, including thermocouples and RTD elements. It accurately displays process temperatures and provides precise output control signals—time proportional, linear, or valve positioning—to maintain processes at desired setpoints. The controller operates in PID control mode for both heating and cooling applications, featuring on-demand auto-tuning to establish optimal tuning constants. Additionally, the TCU offers manual mode operation, allowing direct control of outputs, and can be programmed for ON/OFF control with adjustable hysteresis. Dual 4-digit displays enable simultaneous viewing of process temperature and setpoint, while front panel indicators inform the operator of controller and output statuses.
Key Features:
- Universal Sensor Input: Supports a variety of temperature sensors, including thermocouples and RTD elements.
- PID Control with Auto-Tune: Provides precise control for heating and cooling applications, with on-demand auto-tuning to determine optimal PID constants.
- Manual and ON/OFF Modes: Allows manual operation for direct output control and programmable ON/OFF control with adjustable hysteresis.
- Dual 4-Digit Displays: Enables simultaneous viewing of process temperature and setpoint for enhanced monitoring.
- Front Panel Indicators: Provides clear status information of the controller and outputs.
