the Model T16 Controller accepts signals from a variety of temperature sensors (thermocouple or RTD), while the Model P16 Controller accepts either a 0 to 10 VDC or 0/4 to 20 mA DC input signal. Both controllers can provide an accurate output control signal (time proportional or DC Analog Output) to maintain a process at a setpoint value. 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. the comprehensive programming allows these controllers to meet a wide variety of application requirements.
