The status output is connected internally
with a 10 kOhm resistor against 0 V.
Status OUT
ESX10-TB-114/-124 (signal status OUT),
at U
B
= + 24 V
+ 24 V = S1 is ON, load output connected
0 V = S1 is ON, load output locked
and/ or switch S1 is OFF
red LED lighted
Status OUT
ESX10-TB-127 (signal status OUT
inverted), at U
B
= + 24 V
+ 24 V = S1 is ON, load output locked
red LED lighted.
0 V = S1 is ON, load output connected
and/or switch S1 is OFF.
OFF condition
