M2 Engine Controller

Category: Products » Sensing & Control Equipment

The Observant M2 Engine Controller is an electronic protection and control system for diesel and petrol engines. It can work as a stand-alone, or as part of the Observant Remote Monitoring Solution.

You can link the M2 with an Observant telemetry product via an industry standard RS485/Modbus communications interface to give you fully automated control. And in addition to timer-based control, you can use sensor inputs from remote sites to start, stop or set the speed of the engine.

The M2 can also work locally with a range of standard automotive sensors, such as RPM, engine oil pressure and water temperature. You can add these sensors to provide a fully configurable, engine fault-shutdown and alert system. You can also use sensors for fuel level, water pressure and flow to increase diagnostic capability.

Engine speed can be controlled using an optional throttle control kit. You can set the speed remotely and locally, and engine warm and cool-at-idle periods to reduce wear and tear. You can also control power to ancillary equipment such as electric pumps and heaters using a pair of fully adjustable auxiliary outputs.

All Observant products are designed with safety in mind. An emergency stop switch and a 100+ decibel pre-start warning siren are standard features of the M2.

The M2 can also use an optional solar-charger kit to charge the engine battery, which means the battery is healthy at all times. It can also operate in the harshest of Australian climates, and features robust environment, chemical and pest protection.

Using IP65+ rated fittings, door seals and cable conduit means you can install the M2 with minimum additional hardware, while maintaining maximum environmental integrity.

The Observant M2 is covered by a three year warranty and backed with unparalleled after sales service.
