iSMA-B-FCU

iSMA

iSMA-B-FCU is a fully programmable controller, built with the aim of controlling the FCU. The controller is factory-equipped with the two most popular open communication protocols ModbusASCII/RTU and BACnet/MSTP, which are selected using the DIP switches.

GET A QUOTE

To minimize time and simplify commissioning prices the controller is equiped with universal application, which supports the most popular types of FCU. The DIP-switch allows the user to adjust the parameters of the application. Additionally, in the BACnet protocol, the application has the built-in function which allows to automatically bind Master and Slave controllers in the groups (20 groups on the bus, up to 6 devices in one group).

In the case of if the application does not meet the project requirements, it can be modified or created from scratch. Modification of the application is possible in real-time by USB port or using a simulator on a PC in off-line mode. There are three hardware versions which have  different types of  Outputs and power supply.
