About the product

The iSMA-B-MAC36NL is Niagara controller with 36 onboard IO and license of 100 points and one RS485 port. If more points are needed then you can upgrade in 50 points increment.

The MAC (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 16x UI, 8x AO, 4xDI and 8x DO allow 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 MINI or MIX series I/O modules or to integrate with other subsystems.
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 (touch-screen support).
There are two more hardware versions of the controller with the second RS485 port and M-Bus interface available.
