Process controllers take an input signal (temperature, pressure, flow or level) and maintain a setpoint using an output (relay, voltage pulse, current or linear voltage, depending on the model). Various controllers support modes such as PID, ON/OFF, Ramp/Soak, and Manual.
Process and temperature controllers are powerful process control tools, but they offer simple operation. Process controllers take a signal from a temperature device, such as a thermocouple or RTD, or from a pressure/ flow/ level sensor, and maintain a setpoint using an output signal.

Economical SOLO basic single-loop temperature controllers control a heating or cooling process using input from a temperature sensor and maintaining a setpoint using an application-specific output.
SOLO standard single-loop temperature controllers offer dual outputs to control heating and cooling simultaneously, using a temperature sensor or analog input and maintaining a setpoint with an application-specific output.
ProSense advanced process controllers can perform temperature, pressure, level, flow, and other process variable control applications. These 1/4 DIN controllers offer a variety of control, input, output, alarm, and communications options (depending on model), and are configured via the keypad/display or the free downloadable software.
