Input data	Coil side Nominal input voltage U_N: 120 VAC Input voltage range: 93.6 VAC ... 165.6 VAC (20°C) Mains frequency: 50/60 Hz Drive and function: monostable Drive (polarity): non-polarized Typical input current at U_N: 13 mA Typical response time: 5 ms ... 15 ms (depending on phase relation) Typical release time range: 5 ms ... 20 ms (depending on phase relation) Status display: Yellow LED
Output data	Switching Contact switching type: 4 changeover contacts Type of switch contact: Single contact Contact material: AgNi, hard gold-plated Note: If the specified maximum values for multi-layer contact relays are exceeded, the gold plating is destroyed. The maximum values of the power contact relay are then valid. This can result in a shorter service life than with a pure power contact.
