iSMA-B-MAC36NL is a compact Master Application Controller with built-in different types of I/O and operating in Niagara Framework environment. Using the specific local I/O set 16x UI8x AO4x DI and 8x DO allows to use the device in different applications. The controller provides control, data logging, alarming, scheduling, integration and visualisation.

To allow IP connectivity there are 2x Fast Ethernet ports which can operate as two independent ports.
Built-in 1x RS485 can be used to expand number of I/O by connecting iSMA-B-MINI or iSMA-B-MIX series I/O modules or to integrate with other subsystems.
iSMA-B-MAC36NL-RS is equipped with an additional RS485 port.

iSMA-B-MAC36NL provides rich graphical interface displaying on a standard Web browser or on external display connected to built-in HDMI and USB port (touchscreen support).
