Features and Benefits
5V DC Operating Coil
The relay is designed for a 5V DC control supply, making it suitable for compatible low-voltage electronic control circuits. Verify the coil voltage before replacing or installing the relay.
DPDT Contact Arrangement
Two changeover contact sets allow the relay to switch two separate circuits or provide complementary switching functions, subject to the circuit design.
8A Contact Rating
The RT424005 supports switching applications within the manufacturer’s specified current, voltage and load limits. Inductive loads and high inrush currents may require additional consideration.
PCB Through-Hole Mounting
Solder-pin terminals support direct installation on a compatible printed circuit board. Confirm the PCB footprint and terminal layout against the manufacturer’s drawing before assembly.
Flux-Resistant Housing
The standard RT424005 variant features a flux-resistant enclosure suitable for appropriate PCB assembly processes. It should not be assumed to be a wash-tight version.
Typical Applications
Depending on the electrical requirements, the Schrack RT424005 may be used in:
– Electronic control boards
– Industrial automation modules
– Boiler control equipment
– Timer and sequencing circuits
– Garage door control systems
– Point-of-sale automation
– General-purpose electronic switching
