Connections
Example 2: Connection via contacts that close to the power supply positive (+) (the opposite to the previous example).
The inputs can be connected to the device's power supply positive (+) by means of a switch.
The inputs common is to be connected directly to the power supply negative (-).

Example 3: Connection with a signal generator with different voltage references.
The inputs can be connected directly to a third-party device that provides an output with voltage and current values compatible with the inputs of the 21126
control.
The inputs common is to be connected directly to the negative (-) of the power supply of the third-party device.
