Expanding the number of input and output points in HVAC/R control systems has never been easier. The CAREL PCOE004850 is more than just an auxiliary device—it acts as an extension of the main controller, helping optimize the management and control of complex systems based on the pCO Sistema platform without requiring replacement of the main controller.
1. Flexible I/O Expansion – Expand Your System's Connectivity
The key advantage of the CAREL pCOE is its ability to transform standard controllers into larger-scale control systems. Designed specifically for the pCO platform, it allows users to:
- Increase I/O Capacity: Quickly add additional analog and digital inputs and outputs.
- Flexible Connectivity: Supports applications ranging from smaller systems using tLAN to larger networks using RS485/Modbus.
- Wide Compatibility: Designed to work with pCO1, pCO2, pCO3, pCO5, pCO XS, and pCO compact controller platforms.
2. Intelligent Control Technology – Accurate and Reliable
The product is designed to meet CAREL's demanding industrial control standards:
- Universal Inputs: Supports common sensor types including NTC, PT1000, 0–20 mA, 4–20 mA, 0–5 V, and 0–10 V.
- Stable Operation: Designed for continuous operation in demanding industrial environments, with an operating temperature range of -10°C to +60°C.
- Space-Saving Design: The DIN rail-mounting design allows for neat and efficient installation inside electrical control cabinets.
