Automation Direct introduced the new SOLO process/temperature controller line with 22 different models.

Available in four standard DIN sizes, each is equipped with a dual four-digit, seven-segment display, useful for process variable and set-point display. Each model offers dual output control, making it suitable for heating and cooling processes. Output configurations are available in various combinations of mechanical relays, pulse outputs and voltage or current outputs. A build-in autotune function with PID control features faster and easier setups, according to the company's press release.

Flexible control modes include PID, ramp/soak, on/off and manual operation. Universal inputs are standard on all controllers.

SOLO process/temperature controllers support 13 types of temperature inputs and five types of analog inputs. All units offer RS-485 serial communications, allowing use of free software to configure and monitor up to eight SOLO controllers  using Modbus RTU or ASCII protocols. This utility provides the ability to monitor and log historical data and save it to text files. RS-485 serial communications provides connection to a human-machine interact, PC or PLC, allowing applications to react to data read from the controllers.

Controllers can also be configured manually with a keypad on each unit.
