The typical connection for supervised inputs is shown in
the resistors close to the contact.
Figure 23 Supervised input connection
Yellow resistor: 1210 Ohm 1%
White resistor: 392 Ohm 1%
Close contact resistance: 296 Ohm
Open contact resistance: 1210 Ohm
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
Use a twisted-pair cable for the contact cables. Make sure that the cables
correspond in size to the norms indicated in section INPUT WIRES...
Max contact resistance = 25 Ohm
