Product Description:
The Danfoss creates this 080Z0191 controller for precise capacity control in refrigeration and HVAC applications. The company focuses on designing unique products that work perfectly in industrial automation.
The 080Z0191 controller supports a maximum of five additional analog inputs and includes eleven built-in analog input channels for extended monitoring capability. The application area centers on capacity control by ensuring stable operation in both pressure and temperature-dependent systems. The unit carries approvals including C UR US, C-TICK, CE, EAC and LLC CDC TYSK by demonstrating adherence to international compliance and safety standards. It operates through pressure or temperature signals while the integrated PI control mode ensures responsive regulation. The communication is flexible through IO Extension, LON RS485, RJ11 (CAN) to display and a USB-B to PC by providing versatile connectivity for system installation. Its compressor modulation is used in both step and speed modes for effective load management. The condenser control function is pressure and temperature-based based with an enclosure rating of IP10. This parameter is suitable for controlled environments. The unit works by enabling optimized air circulation for better performance and working.
The 080Z0191 controller’s supply voltage requirement is 24 V DC by ensuring linkage with standard control power supplies. The unit consumes only 8.0 VA power which aids in ensuring efficient functioning of its parts. The UL evaluation confirms the link with North American standards. It holds a very lightweight configuration of only 0.65 Kg which is easily handled in industries. It has a tolerance of about 95% for moisture and humidity. This unit is supported by Wake Industrial with a one-year exchange guarantee for reported issues.
