The TCU Controller accepts signals from a variety of temperature sensors (thermocouple or RTD elements), precisely displays the process temperature, and provides an accurate output control signal (time proportional, linear, or valve positioning) to maintain a process at the desired control point. A comprehensive set of easy to use steps allows the controller to solve various application requirements.
The controller can operate in the PID control mode for both heating and cooling. On-demand auto-tune establishes the tuning constants. The PID tuning constants may be fine-tuned by the operator at any time and locked out from further modification. The controller employs a unique overshoot suppression feature that allows the quickest response without excessive overshoot. The unit can be transferred to operate in the manual mode, providing the operator with direct control of the output. The controller can also be programmed to operate in the ON/OFF control mode with adjustable hysteresis.
Dual 4-digit displays allow viewing of the process temperature and setpoint simultaneously. Front panel indicators inform the operator of the controller and output status. Replaceable and interchangeable output modules (Relay, SSR Drive, or Triac) can be installed for the main control output, alarm output(s), cooling output, and Valve Positioner outputs.
A NEMA 4X/IP65 rated bezel is available for wash down applications and similar environments, when properly installed. Modern surface-mount technology, in-house assembly and testing, and high immunity to noise interference makes the controller extremely reliable in industrial environments.
Note: Output Modules are NOT supplied with the controller. When specifying the controller, be sure to purchase the appropriate output module for the Main Control Output and if necessary, the alarm output(s), the secondary output, and valve positioner outputs.
The Logic/SSR Drive Module is a switched DC source, intended to drive the DC input of an SSR power unit. It should never be connected to line voltage.
All modules are packaged separately and must be installed by the user.
