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. ## **Features** - **1/16 DIN Dual Display** - **Single/Dual Universal Inputs** - **Fast Speed up to 470 Samples/Sec** - **Programmable by NFC/RFID** - **Supports Heating/Cooling P.I.D** - **Universal Power Supply Option** - **UL Certified** ## The CN40x series includes 5 versions: |**Models with power supply 24..230 VAC/VDC ±15% 50/60 Hz – 6 Watt/VA**|**Models with power supply 24..230 VAC/VDC ±15% 50/60 Hz – 6 Watt/VA**| |---|---| |**CN401-11445**|1 analogue input + 2 relays 2 A + 2 SSR + 2 D.I. + 1 analogue output V/mA| |**CN401-11445-C4**|1 analogue input + 2 relays 2 A + 2 SSR / D.I. + 1 analogue output V/mA + RS485| |**CN401-111445**|1 analogue input + 3 relays 2 A + 2 SSR + 2 D.I. + 1 analogue output V/mA (1 D.O. + 1
