The CAREL c.pCO represents the cutting edge of the company's pCO family of programmable controllers, specifically engineered as a powerful and flexible solution for managing complex HVAC/R applications. Designed for OEMs in the chiller, heat pump, air handling unit (AHU), and rooftop markets, the c.pCO distinguishes itself through a unique combination of advanced hardware features, deep software integration, and a strong focus on networked connectivity. The controller is available in multiple sizes and can be mounted on a DIN rail or panel, offering a compact footprint of just 4 DIN modules for space-constrained applications.

A key differentiator for the c.pCO is its integrated driver for bipolar electronic expansion valves (EEVs), featuring proprietary Ultracap technology. This ensures that in the event of a power failure, the EEV can be reliably driven to a fully closed position, enhancing system safety and protecting the compressor. The controller is a native BACnet Building Controller (B-BC) and is certified by the BACnet Testing Laboratories (BTL), guaranteeing seamless and reliable integration into any BACnet-compliant Building Management System (BMS). Beyond its BACnet capabilities, the c.pCO offers an extensive suite of IT-friendly protocols, including Modbus TCP/RTU, HTTP/HTTPS, FTP/FTPS, SNMP, and OPC UA, making it a first-class citizen on modern IP networks.

The c.pCO platform is built for flexibility. Its I/O system leverages a CAREL proprietary ASIC to offer up to 10 universal channels, which can be independently configured via software as analog inputs (NTC, PT100/500/1000, 0-10V, 4-20mA), digital inputs, or analog outputs (0-10V, PWM). This minimizes hardware variants and simplifies inventory. Networking is handled by up to two built-in Ethernet ports that support daisy-chain topologies, eliminating the need for external switches and featuring galvanic isolation for robust operation. Additionally, the controller provides three standard serial interfaces and two optional expansion slots for further connectivity.

Software development for the c.pCO is supported by two distinct environments: the established c.suite and the new STone OS. STone-based models are designed in strict compliance with the IEC 62443 cybersecurity standard, incorporating advanced features such as secure boot and digitally signed firmware to protect against unauthorized access and tampering. These models also natively support direct connection to CAREL's tERA cloud platform and mobile apps, enabling advanced remote management, data visualization, and predictive maintenance strategies. With its unparalleled blend of safety, connectivity, and security, the c.pCO is a future-proof core for next-generation, energy-efficient HVAC/R systems.
