Intelligent Industrial Alarm Modems (MAM)

Preloaded PLC protocols and increased numbers of alarm levels

Mitsubishi’s range of Intelligent Industial Alarm Modems (MAM) bring telemetry solutions to a new level. Each unit is available with preloaded PLC protocols for connection to Mitsubishi Alpha 2, FX and System Q controllers. This means that control and telemetry functions can be brought seamlessly together with the minimum of effort. All controller variables are then directly monitorable without the need to write any special progams in the controller.

Each MAM model comes with 2MB of on-board user memory that can be expanded up to 64MB. This is especially useful when the on-board data logging option is used as more operational values can be stored for a longer period.

The intelligent Industrial Alarm modems are available with connection to analog PSTN and GSM telephone networks. There are three further model variations offering increased numbers of Alarms, Alarm level etc.
