Control unit Input I0 & Inputs and Outputs
exp. board 4583, Input 0-4

Not supervised

Normally open (R > 2K)
or
Normally closed (R < 2K)
Activation time: >1 sec.
Connections, see drawing 128-22.

Supervised

Each supervised input can be in four different states:
 Open circuit (cut-off)
 Not activated (quiescent)
 Activated
 Short-circuit
Depending on the selected logic, Normally open (high resistance) or
Normally closed (low resistance), the following table is valid.
Line resistance R
R > 6K8
6K8 > R > 2K
(nom. 3K3)
2K > R > 70
(nom. 680)
R < 70
Input line fault
If open circuit (cut-off) or short-circuit is detected on a supervised
input, a fault will be generated in EBL128 and the following fault
message will be displayed:
FAULT: Programmable input
