AutomationDirect adds Basic Single Loop Temperature Controllers

Economical SOLO® Basic temperature controllers from AutomationDirect 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 (depending on model).

The 1/16 DIN panel size SOLO basic controller operates on 100 to 240 VAC 50 / 60 Hz input power. Two 4-character 7-segment LED displays indicate process value (PV) and setpoint value (SV); red for PV and green for SV (°F or °C selectable). 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, 4 types of RTD temperature sensors, and support three control modes: PID, ON/OFF, and Manual. An Auto Tuning (AT) 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.

With UL, CUL, and CE agency approvals and backed by a 2-year warranty, SOLO basic temperature controllers start at $39.00.

With more capabilities (starting at $94.00), 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.
