These powerful 1/8 DIN size SOLO 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 (relay, voltage pulse, current, or linear voltage depending on model). SOLO supports four control modes: PID, ON/OFF, Ramp/Soak and Manual.

This is a great controller that has lots of useful features and options. It has been working well for me in a ramp/soak purpose and all the tuning options are helpful. My only complaint, and a minor one that likely doesn't apply to many people, is that the manual wrongly states that the Integral Offset parameter is available in ramp/soak mode.
