Product description
Description
With the Industrial Dual Analogue in Bricklet 2.1, Bricks can precisely measure voltages. Both channels of the Bricklet are calibrated so that the voltage measurement is very reliable.
With configurable events, it is possible to react to voltage changes without constantly polling the values (no polling required).
The Bricklet has no galvanic separation to the Tinkerforge system. This means that there is a direct electrical connection between the terminals of the Bricklet and the rest of the system. If this leads to unwanted connections, ground loops or short-circuits in the respective application, the use together with an insulator Bricklet is advisable.
The Industrial Digital Out 4 Bricklet 2.1 has a 7-pin Bricklet connector and is connected with a 7p-10p Bricklet cable with a brick.
