16+ Channel Online Monitoring System

The A3716 is powerful online monitoring system for rotating machinery. The A3716 system can operate as an independent monitoring system or it can be used as extension of an existing protection system. The A3716 module contains 16 AC, 16 DC and 4 TACHO inputs. All channels are measured simultaneously. The A3716 modules can be easily composed together and by this we can create system with more channels.

The setting and control of A3716 is done in DDS software. The setting has never been easier. The only thing you need to do is to create the tree of machines, measurement points,required readings and assign them to appropriate channels. Then you just press START and the readings are done automatically.
