*Move on up to our newest line of PID Controller, the CNPT Platinum Series controllers with Modbus connectivity, expanded ramp and soak programs, universal inputs, and simple PC programming.*
"The DwyerOmega CNI-Series offers a line of universal input, 1/32, 1/16, and 1/8 DIN high accuracy controllers designed to deliver precision, flexibility, and reliability across a wide range of temperature and process control applications. Built with multiple input types—thermocouples, RTDs, voltage, and current—these controllers provide consistent performance and stable readings even under changing environmental conditions.
Each controller in this series features excellent accuracy (± 0.03% of reading ± 0.03% of range), high common-mode and normal-mode rejection (CMRR/ NMRR), and tunable control options (PID, on/off, reverse or direct action), giving engineers the control they need to fine-tune system responses.
Visually, the CNI-Series includes bright, easy-to-read displays and intuitive color indicators for status or alarms, making system monitoring easier at a glance. Installation is streamlined thanks to standard DIN panel sizes, screw terminal wiring, and robust housing with front bezels built to handle industrial conditions.
Backed by the DwyerOmega brand, this high accuracy controller line is a dependable choice for process plants, automation systems, OEMs, and any environment where precision, durability, and user-friendly control are essential."
