CN400-Series

An additional programming tool is available the Omega Google App - Direct Link relying on RFID/NFC connectivity and allowing straightforward programming without additional wiring and programmable via Android devices.

Description

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. Serial communication standard is RS485 with Modbus RTU/Slave protocol. The CN400 Series power supply has an extended range of 24 to 230VAC / VDC with galvanic insulation of the net for the single loop version, while the model with double analog input provides two versions: 115 / 230 VAC or 24 VAC / VDC.
