Carel cpy000u200 Humidifier Control Board Rev 1.390

Carel CPY000U200 Humidifier Control Board Rev 1.390 is the electronic control module used with CAREL KUE humidifier kits to regulate single‑phase, 200 V humidification systems. The board serves as the central controller for the humidifier, interfacing with kit sensors and actuators and exposing a Modbus RTU serial interface for external control and monitoring. It is configured for Modbus RTU at 9,600 baud with a fixed address of 1, enabling integration with compatible controllers or building management systems. The CPY000U200 provides digital and analog I/O for remote enabling/disabling, status reporting, and alarm signaling, including signals for drain, fill, and other humidifier functions, and it can be paired with the optional CPYTERM000 display for local readouts of status and alarms. This revision 1.390 board is designed for use with CAREL humidifier kits in HVAC or process environments where precise humidity control is required, and it adopts the standard CAREL CPY family hardware and software interfaces to ensure compatibility with Carel cabling and terminations.
