Key Features
- SPDT contact configuration rated for 16 A at 400 V AC resistive load, enabling control of high-power AC circuits from low-current 24 V DC control signals
- 24 V DC coil with 1440 Ω coil resistance and 400 mW power consumption, compatible with standard industrial PLC output cards and 24 V DC control buses
- Compact 29 mm × 12.7 mm × 15.7 mm body with through-hole PCB mounting for reliable integration into relay boards and panel-mount control systems
Applications
The RZ03-1C4-D024 is used in industrial automation equipment, building management systems, and HVAC control panels where a 24 V DC coil drives switching of high-current AC loads up to 16 A at 400 V. Its SPDT configuration supports both normally-open and normally-closed circuit control, making it suitable for motor starter auxiliary contacts, lighting control, and safety interlock circuits. The relay is compatible with standard DIN-rail relay sockets used in PLC-driven panel assemblies and machine control cabinets.

Frequently Asked Questions
What is the coil voltage and maximum AC switching capacity of the RZ03-1C4-D024 relay?
The RZ03-1C4-D024 operates on a 24 V DC coil with 1440 Ω coil resistance, drawing approximately 17 mA (400 mW) at rated voltage. The SPDT contacts are rated for 16 A at 400 V AC on resistive loads, making it suitable for controlling single-phase industrial equipment, lighting circuits, and motor auxiliaries in European and North American 230 V to 400 V mains environments.
How does the coil power of 400 mW in RZ03-1C4-D024 affect compatibility with PLC digital output modules?
At 400 mW and 24 V DC, the RZ03-1C4-D024 draws approximately 16.7 mA from the coil supply. Most industrial PLC relay or transistor output cards can source 100 mA to 500 mA per channel, so a single PLC output channel can directly drive 3 to 10 of these relays in parallel without exceeding rated output current, eliminating the need for external relay driver ICs in standard panel wiring.
For a 3-phase motor contactor auxiliary circuit, when is RZ03-1C4-D024 an appropriate selection over a solid-state relay?
The RZ03-1C4-D024 is preferred over a solid-state relay (SSR) when true galvanic isolation is required between control and load circuits, when zero-crossover switching is not needed, or when cost constraints favor electromechanical solutions. Its 16 A at 400 V AC rating covers most single-phase motor auxiliary and interlock circuits up to approximately 4 kW without heat-sink requirements, whereas SSRs of equivalent current rating typically require thermal management above 5 A.
