1 Introduction
The iSMA-B-AAC20 is a universal controller with built-in different types of I/Os, which
operates based on the Sedona framework environment. Using a specific set of inputs and
outputs (8 UI, 4 DI, 6 AO, and 4 DO) allows to use the device in different applications. The
controller provides control, data logging, alarming, scheduling, integration.
To allow IP connectivity there are 2 Ethernet ports, which operate as two independent
ports. A built-in RS485 port can be used to expand the number of I/Os by connecting
MINI or MIX series I/O modules or to integrate with other subsystems.
The iSMA-B-AAC20 controller communicates in BACnet and Modbus protocols, and
additionally can come with M-Bus or DALI extensions.
The unique option in iSMA-B-AAC20 controllers is an LCD display, which allows for basic
service of the controller.
