iSMA-B-MAC36NL User Manual


iSMA-B-MAC36NL is a compact Master Application Controller with built-in different types of I/O and operating in the Niagara Framework environment. Using the specific local I/O set of 16 UI, 8 AO, 4 DI, and 8 DO allows to use the device in different applications. The controller provides control, data logging, alarming, scheduling, integration, and visualization.

To allow the IP connectivity there are 2 Fast Ethernet ports, which operate independently. Built-in 1 RS485 can be used to expand the number of I/O by connecting MINI or MIX series I/O modules or to integrate with other subsystems.

Dedicated microSD card stores real-time data, history logs, and alarms as well as the operating system, Niagara Framework, and licenses.

There are 2 USB ports, one of them operates as a host port and the other one in the OTG mode.
