Single relay-REL-IR4/LDP- 24DC/4X21AU-2903670
Technical data
Coil side
Input voltage range in reference to UNsee diagram
Typical input current at UN42 mA
Typical response time 13 ms
Typical release time 14 ms
Protective circuit Damping diode
Status display Yellow LED
Power dissipation for nominal condition 1.01 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.
