The connection terminal considerably simplifies the connection of wires to the data recording device. Instead of having to solder the wires to a 25-pin D connector, you can simply insert the prepared wire ends into the screw terminals on the terminal board. The connection terminal is also equipped with soldering eyes so that you can also connect resistors that distribute the input voltage to all channels according to a known factor in order to expand the measuring range by the same factor. For example, if you divide the input voltage by 4, the effective input range of the data recorder on this channel increases from 2.5 V to 10 V.
