Input circuit active
• U
1
= 24 V DC, input voltage at the connection
terminals A1(+) and A2(-) is switched on
○ current consumption is I
1
= 45...55 mA (am-
meter A1)
○ the “RELAY OUTPUT” LED lights up
○ Functional testing of internal fuse and relay
contact circuit:
the connection terminals 13 and 15 are elec-
trically connected, current consumption is
I
2
= 10 mA (ammeter A2)
Input circuit inactive
• U
1
= 0 V DC, input voltage at the connection ter-
minals A1(+) and A2(-) is switched o󰀨
○ current consumption is I
1
= 0 mA (amme-
ter A1)
○ the “RELAY OUTPUT” LED does not light up
○ Functional testing contact set 1:
the connection terminals 14 and T1 are not
electrically connected, current consumption is
I
2
= 0 mA (ammeter A2)
○ Functional testing contact set 2:
the connection terminals T1 and T2 are not
electrically connected, current consumption is
I

= 0 mA (ammeter A2)
○ Functional testing contact set 3:
the connection terminals T2 and 15 are not
electrically connected, current consumption is
