Inputs contacts
Insertion type terminals for input
Possibility of use of cables up to 1.5 mm
2
or AWG16
Number of inputs
3 distinct with common terminal connector
Type of drive
For each input, acquisition of a voltage-free contact for
connection between the individual input and the common point of
the dedicated connector (TB5 pin 3,4,5,6)
Time for change state detection
Closing or opening of the stable external contact for at least 100
milliseconds, any less time trigger will be ignored
Voltage for detection state contacts
12VDC max, the system has its internal voltage reference to
detect contact closure
Current for detection state contacts
Max 10 mA, with the closed contact to the common point
Note:
it is not possible to apply any voltage at the terminal points dedicated to the acquisition of the inputs state
(TB5 pin 3,4,5,6), because it will damage the system
Note:
the individual inputs (including the common point) are not galvanically isolated from each other
