iSMA-B-AAC20


iSMA-B-AAC20 controller is equipped with 22 Inputs/Outputs. The application for control algorithm can be created and modified in real-time by free software iSMA Tool or by standard Niagara AX Workbench.

As an Integration Controller, iSMA-B-AAC20 can be a platform for integration and control of Modbus (RTU, ASCII, TCP), BACnet (MS/TP, IP), 1-Wire, M-BUS (Option) and DALI (Option) devices. This controller has 2x Fast Ethernet ports with switch mode.

Up to 128 devices can be connected to RS485 port (Modbus RTU/ASCII or BACnet MS/TP).

Up to 32 sensors can be connected to the 1-Wire protocol.
Up to 64 DALI ballasts can be connected to DALI interface.
Up to 20 meters can be connected to the M-Bus interface.
iSMA-B-AAC20 controller is equipped with 22 Inputs/Outputs. The application for control algorithm can be created and modified in real-time by free software iSMA Tool or by standard Niagara AX Workbench.

The hardware version with M-BUS interface may be the most suitable version for metering functionality. Up to 20 M-Bus meters can be connected to iSMA-B-AAC20 M-Bus interface. Digital Inputs of iSMA-B-AAC20 can be used as Fast Pulse Counter up to 100 Hz saved in EEPROM memory for pulse meters. The controller gives a possibility of service M-Bus devices connected by IP, for example through iSMA-B-MG-IP gateway. Up to 128 Modbus meters can be connected to RS485 port.
