Single relay - REL-IR4/L-120AC/4X21AU - 2903684
Technical data
Coil side
Mains frequency
50/60 Hz
Typical input current at UN
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
Power dissipation for nominal condition
1.56 W
Contact side
Contact type
