Built for closed-loop PID control, this 1/16 DIN controller takes thermocouple, RTD, thermistor, and analog inputs and provides three relay, two SSR-driver, and one analog outputs. It operates on an AC or DC supply, reads out on a dual 4-digit display, and connects via NFC. Best for oven, furnace, and process temperature regulation.

The CN400 Single/Dual Inputs PID Controller Series stand out for the bright display which ensures optimal visibility and increased level of information for the operator.
The CN400 Series introduces the latest NFC/RFID programming technology with a dedicated App - Omega Direct Link for all Android devices (Free Download from Google Play). No more wiring, cables, or power supply, just quick set-up/updates on site with your phone.
With dual analog input and dual analog outputs model option, the CN400 Series can achieve two separate heating/cooling PID control loops in one device or to handle mathematical operations between two process values. The outputs can be selected as command/multiple alarm modes/analog retransmission.
