6EP1961-3BA21
Both input voltages > switching threshold
At least one input voltage < switching threshold
O.K. if both input voltages are > switching threshold
(contact rating (SELV (ES1) must be maintained) 8 A/AC 240 V, 24 V DC)
6EP1962-2BA00
Both input voltages > switching thresh-
old
At least one input voltage < switching
threshold or the output is switched off
Contact is closed if one or both input
voltages is/are < the switching threshold,
or if the output is switched off.
(contact rating (SELV (ES1) must be
maintained) 6 A/AC 42 V, 30 V DC, how-
ever 100 VA max.)
6EP1964-2BA00
Both input voltages > switching thresh-
old
At least one input voltage < switching
threshold
Contact is opened if one or both input
voltages is/are < the switching threshold.
(contact rating (SELV (ES1) must be
maintained) 6 A/AC 42 V, 30 V DC)
