Sensor Connections
The Sensor Connections guide lists most common Banner and non-Banner sensors and how to wire them to the DX80 devices.
This reference guide lists typical connections. If you have additional questions about a specific sensor or its connection instructions,
please contact Banner Engineering or the manufacturer of the sensor you are using.
Discrete Sensors. Neither the inputs nor the outputs on the DX80 devices are isolated. Under certain operating conditions, externally
powered sensors may need to have ground in common with the DX80 device to which they are connected. The power sources do not
have to be the same.
Analog Sensors. For analog sensors, the ground/dc common of the sensor should be connected to the ground of the DX80 device. For
best results, Banner recommends that the power source for the sensor and DX80 device is the same.
