RAC18-IP

The RAC18-IP controller is a multifunctional device that regulates comfort in a single room or in a building area. The 18 on-board I/Os with Ethernet ports, serial ports and additional extension cards make the controller a versatile system for comfort management, lighting control and integration with the supervision system.

Cutting-Edge High-End Technology

The powerful nano EDGE ENGINE enables unprecedented IoT capabilities for a microcontroller-based device. Minimize development time with native BACnet point exposure, real-time programming, and cloud connectivity.

Openness and reliability

Take advantage of IP connectivity with open protocols such as BACnet, Modbus and ensure maximum energy efficiency for your building with any supervision system. The RAC18-IP controllers connected in series are protected by a fail-safe system on each Ethernet port to ensure maximum reliability.

Seamless Programming and Maintenance

Maintain and program your device in real time from anywhere with a dedicated and free tool. Facilitate the replacement process thanks to the fact that the operating system and user data are stored on a removable SD card.

4 Universal Inputs

Support over 20 types of temperature sensors and measure voltage, resistance, current and dry contact on each universal input.

4 Digital Inputs

Dry contact inputs - designed for monitoring. The 100 Hz fast pulse counter with override function saves real-time values ​​in the controller's non-volatile memory.

5 Digital Outputs

Digital outputs equipped with 3A normally open relays allow direct control without additional relays.

3 Analog Outputs

The 0-10V DC signal with 10mA accuracy, PWM mode and a maximum load of up to 20mA 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 of thermal valve actuators. The outputs can be connected to actuators with 24V AC power supply.

The triac outputs can work as typical binary outputs for binary temperature control or with PWM modulation up to 0.5 A load.
