HELLA's 4RD 007 903-021 is a 24 volt five-pin change-over relay fitted with a diode across the coil rather than a resistor. The diode gives tighter clamping of the reverse voltage spike at switch-off, which matters in 24 V systems running sensitive control modules on the same circuit.
Key Features
- Change-over (SPDT) contact rated 5 A minimum to 20 A maximum at 80°C ambient
- Parallel coil diode for effective spike suppression
- Supplied without bracket for socket installation
- Minimum 100,000 switching operations
Product Details
