Temperature Limit Controllers / PID Temperature Controllers
Process and temperature controllers are powerful process control tools, but they offer very 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.
AutomationDirect's SOLO digital temperature controller is a single loop dual output temperature limit controller that can control both heating and cooling simultaneously.
Four types of control modes: PID, ON/OFF, Ramp / Soak and Manual.
Available outputs include relay, voltage pulse, current, and linear voltage (depending upon controller model)
Up to three alarm outputs available (The SL4824 series supports only one)
Seventeen alarm types available in the initial setting mode
Accepts thermocouple, RTD, or analog inputs
Built in RS-485 interface using Modbus slave (ASCII or RTU) communication protocol
24 VDC input power versions now available
100 to 240 VAC 50 / 60 Hz or 24 VDC input power
1/32 DIN, 1/16 DIN, 1/8 DIN, or 1/4 DIN panel size
Two 4 character 7-segment LED displays: Red for Process value (PV) and Green for Set Point (SV), °F or °C selectable
Auto Tuning (AT) function with PID control
Accepts eleven types of thermocouples, two types of Pt100 RTD temperature sensors, and DC mA, mV, and Volt signals
Two optional Event Inputs available in 1/8 DIN and 1/4 DIN size
Four possible control outputs; Relay, Voltage Pulse, Current, and Voltage (depending on model)
Up to three alarm groups, each with seventeen available alarm types
64 levels of Ramp / Soak control
IP65 (NEMA 4) front panel
