Function diagrams (on reaching the lower measuring range limit of the measuring current
I > 3 mA / 50 mA)
Memory = no
Relay switching behavior = NC (closed-circuit
principle)
I > 3 mA / 50 mA
Memory = no
Relay switching behavior = NO (open-circuit
principle)
I > 3 mA / 50 mA
J = Currently measured current value
I = set threshold value for the current
