And the benefits of single=ended input power

A precision sensor is needed to provide vital feedback on the performance of your inertial project and the input power connection is what breathes life into that sensor. In recent years, engineers have been migrating from a dual-ended power input to single in order to save on costs and maximize efficiency. If you need to start buying sensors with single-ended input power, but are not sure how accommodate for them, this process is easier than you think.

The Benefits of Single-ended Input Power

Dual-ended power input requires three wires, one for the positive power supply, one for the negative power supply and a third to be used as the common return connection for both positive and negative supplies. With single-ended, only two wires are needed, one for the positive power supply connection and the other for the power return connection to the supply. With less equipment, this saves on costs and creates a more efficient process. This will also save you headaches since one less connection means there is one less thing that can go wrong.

How to Accommodate for a New Sensor with Single-ended Input Power

If you’ve been using dual-ended power input sensors for years, accommodating for single is a smoother process than you may realize. Dual-ended input power typically requires ±12 to ±18 Vdc, but single power encompasses this with a range of +9 to +18 Vdc.

Your connection equipment will not need to be replaced as one wire end can be hooked up to the positive connection of the sensor. There may need to be additional changes in the wiring, but this depends on how your grounding is configured.

What Kind of Sensors Use Single Input Power

A number of inclinometers, using various technologies, offer the option of single-ended input power. Force balanced inclinometers include the LSOX, LCF-300, SMI and RMI .

The JMI-100/200 inclinometer can offer both single and dual input power as well as its accelerometer cousin, the JMA-100/200/300. Not sure what connection is best for your requirements? Contact us and a sensor expert will help you find the best solution.
