The CN616A-Series is our newest affordable multi-channel process controller offering high accuracy measurement over a wide temperature range. The input, power and communications are isolated allowing for simplified deployment and more reliable operation. The rugged extruded aluminum ¼ DIN case combines with the improved isolation to provide an extremely durable product.

The CN616A-Series is an excellent fit for OEM instrumentation, automotive and aerospace test stand, factory automation, and power generation applications. The universal input supports 9 thermocouple types (J, K, T, E, R, S, B, C, and N), 2 wire RTDs (Pt 100, Ni 120, Cu 10), DC voltage (0-1 Vdc), and DC current (0 – 24 mA). Both universal AC and Isolated DC power supply options are available and a user selectable RS232 or RS485 serial port interface is standard on all models. A security password can be enabled to prevent front panel tampering of the configuration and all options are software selectable eliminating the need to disassemble your panel to set jumpers. The CN616A-Series supports the measurement and control of 6 independent zones. Independent alarms are available for each zone and each alarm can be configured for above (HI), below (LO) or HI/LO triggering. Alarms conditions are indicated on the display and may be used to activate either of the 2 SPDT alarm outputs. All six zones are independently controlled. Users can select from On/Off, PID and Ramp & Soak control modes for each zone. Each zone can also be set to either Heating or Cooling allowing a wide range of applications in a single package. The auto-tune feature provides an easy way to setup initial control parameters.

Software: The CN616A-Series is most easily configured with Omega Sync, a software tool that enables users to configure device runtime parameters, view process values, and seamlessly export data. At the moment, Omega Sync supports the CN616A-Series and DP606A/DP612A devices and we look to expand its reach to future products. For long-term data storage, our experts recommend using Omega Enterprise Gateway (OEG) that provides a powerful data historian, alarming, visualization and OPC-UA integration.

An internal output power supply provides 5Vdc and 25mA. External output power source voltage range is 3.3-36Vdc, and what is the current rating for the external power supply? thanks

Asked by: AnnaH
Thank you for the inquiry. External power supply should be rated to at least 3 watts. Best regards OMEGA

What output signals does the controller produce and how do you power the LV series heaters.

Asked by: LArrow
Thank you for your inquiry. This unit has an Internal Control Output Voltage: 5Vdc @25mA per channel which will trigger DC Controlled Solid State Relay whether it controls a AC or DC Load.

Will software previously written for the CN616 run on the new CN616A?

Asked by: DPSdave
Thanks for your question. Unfortunately no, but we have a brand new software for CN616A. Omega provides software for the user to work with CN616A out of the box. For setup and configuration, we offer Omega Sync. For long term data logging and integration, you can use OEG. Please contact our Tech Support team if you have any further questions. Omega Sync: OEG:
