EOL resistor: 3.3 kΩ
Max. cable resistance, both conductors: 80 Ω
Input monitoring
The resistance range of the entire line – measured at the input terminals
'IN_MON+' and 'IN_MON-' when the site is switched off – determines the defined
state of the input status. The status varies depending on the input type configured.
The status ACTIVE has two values:
ACTIVE 1 is when the 1200 Ω resistor is used
ACTIVE 2 is when the 680 Ω resistor is used and
ACTIVE 1 + 2 is when both resistors are used ('simple switchable' and
'complex switchable')
The circuits and the definition of the coverage areas per input type are listed below.
