    25 Series 1/4 DIN Auto Tuning PID Controller with Thermocouple, RTD or Process Signal Input

    Overview

    The Athena Legacy 25 is a 1/4 DIN Single Loop Auto Tuning PID panel mounted, that can be used for precise control of a single loop with two independent outputs. The controller accepts 7 thermocouple types, Pt100 RTD, mV, voltage, or current input. RS-232 or RS-485 communications are available (please contact us for details), and two digital LED displays provide visual indication of various controller functions.
