iSMA-B-AAC20-LCD-M
iSMA
AAC20-LCD-M controller is an advanced device to control building automation and HVAC systems. AAC20-LCD-M provides 8xUI, 4xDI, 4/6xAO and 4xDO. Use of SVM (Sedona Virtual Machine) allows for quick and easy programming in real time-anytime from anywhere.
The controller provides new extension ModBus which supports communication with electric, water and heat meters for up to 20 devices.
The “Out of box” controller has a built in Modbus Gateway TCP/IP to Modbus ASCII/RTU, enabling you to connect additional modules/devices that communicate via Modbus RS485 without programming it.
Inputs & Outputs
