RAC18-IP Free Programable Room Application Controller

Room and Zone Management The RAC18-IP controller is a multifunctional device providing comfort in a single room or a zone in the building. Onboard 18 I/O with Ethernet and serial ports make the controller a versatile system for comfort management, light and blind control, integration and monitoring. High-end Technology at the Edge The RAC18-IP's powerful, IoT ready nano EDGE ENGINE allows unprecedented capabilities for a microcontroller-based device. Take advantage of a time-saving automatic BACnet exposure, real-time programming, and cloud connectivity. Openness and Reliability Take advantage of the IP connectivity with open protocols like MQTT, BACnet, and Modbus, and ensure the highest energy efficiency for your building with any supervisory system. Daisy-chained RAC18-IP controllers are protected by a unique fail-safe system on each Ethernet port to provide maximum reliability. Seamless Programming and Maintenance Maintain and program your device from anywhere in real-time with a dedicated, free of charge tool. Easy replacement process with system and user data saved on a removable SD card. 4 Universal Inputs Support for over 20 types of temperature sensors and voltage, resistance, current, and dry contact measurements on each universal input. 4 Digital Inputs Dry contact inputs - made for monitoring. 100 Hz fast pulse counter with override function saves the real-time values to the non-volatile memory of the controller. 5 Digital Outputs Digital outputs equipped with normally open 3A relays allow for direct control without additional relays. 3 Analog Outputs 0-10 V DC control with 10 mA accuracy, PWM modes, and a maximum load of up to 20 mA to power external relays makes the output suitable for a variety of scenarios. 2 Triac Outputs The controller is equipped with two triac outputs that can be used for heating and cooling thermal valve actuators. Outputs can be connected to actuators with a 24 V AC power supply. Triac outputs can work as typical binary outputs for binary temperature control or with PWM modulation up to 0.5 A load.
