Power 100~240VAC Contact Input 16port,Contact Output 16port,1port (SSR) Analog Input X 3,Analog Output X 4 Communication Port(RS485 Modbus RTU) X 4 The configurable controller, powered by a high-performance microprocessor, is designed to efficiently control cooling, heating, humidification, and dehumidification. It provides analog outputs (voltage and current) according to field conditions, enabling precise control of inverters and heating/cooling valves. The controller supports a universal external monitoring communication protocol (MODBUS RTU), allowing seamless integration with HMIs or web servers. Built-in protective features help extend and safeguard the compressor’s lifespan, ensuring safer, more reliable control. Additionally, based on optional configurations, it can store system status during alarm occurrences, assisting users in quick and efficient maintenance. - Step Control Functionality: Heating: 5 steps (including SSR control) Cooling/Dehumidification: 3 steps Humidification: 2 steps for pan type, with support for evaporative and electrode-type systems - Analog Output Configuration: Individual settings for current temperature, humidity, cooling, heating, humidification, dehumidification, and cooling dehumidification functions - External Monitoring Communication: 2 channels using the MODBUS RTU protocol for external monitoring 2 channels using the Seungil protocol for main/remote display communication - Power Supply: SMPS design supports free voltage operation (100~240V), offering flexibility and compatibility for various installations
