АСМ-IP2 Analogue subsystems module

Analogue subsystems module АСМ-IP2 is designated to be used at industrial and transportation sites in Armtel distributed and centralized Intercom and PA/GA communication systems. АСМ-IP2 allows to connect to a system various analogue equipment, amplifiers, analogue low-frequency lines and discrete control lines, signaling devices. АСМ-IP2 provides interaction with automation and alarm devices. АСМ-IP2 module has 1 A/F channel for connecting analogue devices and 8 I\O digital bi-directional control lines.
