¹⁾ Limit values.
²⁾ Provide suitable arc suppression for inductive or capacitive loads. Relay contacts are separated from the supply voltage by a basic isolation of 3 mm. Depending on the application, additional isolation might have to be applied in the user’s circuit.
³⁾ With light/dark ratio 1:1.
⁴⁾ A = V_S connections reverse-polarity protected.
⁵⁾ C = interference suppression.
⁶⁾ Reference voltage: 250 V AC, overvoltage category 2.
⁷⁾ UL: 0 °C … +60 °C.

Safety-related parameters

¹⁾ Only for devices containing electro-mechanical components. In this case, the MTTF_D value of the entire device must be calculated from the given B_10D value, the number of switching cycles and the given MTTF_D value.
