More information about how a PID Controllers works in this link.

Monitor and control temperature or process applications with precision using the CN245 Series DIN rail mountable controllers. The CN245 Series provides dual LED displays for local indication of process value and setpoint value. Control methods include on/off, PID, auto-tune and manual-tune. Controller includes a 3 setpoint ramp/soak control feature, alarm functions, RS485 communications and heater loop break alarm.

In addition to operation as a multi-setpoint PID controller, the unit can be ideally used as signal converter thanks to a universal input (selectable by parameter for up to 18 different signals) and the analogue output which is galvanically isolated and programmable for rescalable retransmission of process value.

An optional software package CN-SW-HW-KIT includes cable and configuration module for quick configuration of units, as well as copying configuration parameters from one unit to another. The configuration module can also be purchased separately and with a built-in battery feature, configuration settings can be downloaded and copied to module without power applied to controller. Module can then be plugged into a new unit without power applied and the configuration setting can be transferred for easy set up for multiple units.
