HVAC and Plant Control

AAC20 controller (iSMA-B-AAC20) is an advanced device to control building automation and HVAC systems. Use of SVM (Sedona Virtual Machine) allows for quick and easy programming in real time. Large number of inputs and outputs allows to integrate with other devices and sensors (AAC20 provides 8xUI, 4xDI, 4/6xAO and 4xDO). Its fast processor allows to control of even very large objects. Big, fully programmable LCD can be used as simple user interface to allows local operation of system.

Built-in RS485 can be used to expand number of I/O by connecting MINI or MIX series I/O modules using Modbus ASCII/RTU. In addition, to increase the versatility of the controller, it supports many open communications protocols like: BACnet, Modbus, SOX, DALI, M-Bus, 1-wire or oBIX (optional).  

AAC20 is mounted in a housing adapted for DIN rail mounting or directly on a panel. Separate, easy to remove connectors allow quick wiring without removing the entire module
