Single relay-REL-IR4/L- 24AC/4X21AU-2903683
Technical data
Coil side
Input voltage range in reference to UNsee diagram
Mains frequency 50/60 Hz
Typical input current at UN66 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
Power dissipation for nominal condition 1.58 W
Contact side
Contact type 4 PDTs
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.
