9 Setting inputs, outputs, and jumpers
Digital inputs
The device has 2 inputs and 2 outputs. The 2 inputs can be used either as
digital dry contacts or supervised contacts.
Usually the IN1 is dedicated to the door contact.
Usually the IN2 is dedicated to the push button (request to exit).
However, the inputs can also be used as general purpose inputs.
The typical connection for digital dry contacts is shown in Figure 22.
Temaline recommends that you establish an electrical environment where
the cables are well separated, even at short runs, especially to the power
cables or external cables which can be essentially subjected to interference
or lightning.
Use a twisted-pair cable for the contact cables. Make sure that the cables
correspond in size to the norms indicated in “Wire characteristics” on
page 7.
Max contact resistance = 25 Ohm
