March 4, 2019 – AutomationDirect has released its SOLO line of basic temperature controllers to provide single-loop control for heating and cooling processes using a thermocouple or RTD input signal and a relay, voltage pulse or current output signal.

The 1/16 DIN panel size SOLO basic controller operates on 100 to 240 VAC 50/60 Hz input power. Two four-character seven-segment LED displays indicate process value (PV) and setpoint value (SV). These basic controllers are IP66-rated for dust and water jet ingress protection (inside suitable enclosure) and have a 0°C to 50°C operating temperature range.

SOLO basic units accept 11 types of thermocouples, four types of RTD temperature sensors and support three control modes: PID, ON/OFF  and manual. An auto-tuning function is available with PID control. On select models there are two alarm outputs available with nine selectable alarm types. Models with alarm outputs can also be configured to use one of the alarm outputs as a second control output, allowing both heating and cooling control or two-stage heating or two-stage cooling control.

The basic temperature controllers have UL, CUL, and CE agency approvals.


With more capabilities, standard series SOLO process/temperature controllers offer dual outputs, ramp/soak control mode, linear voltage output, three alarm outputs and have a built-in RS-485 interface using Modbus slave (ASCII or RTU) communication protocol.
