About 4-20 mAmps Solid State Relay
CARLOGAVAZZI SSR industrial, 1-phase relay with antiparallel thyristor output is the most widely used industrial SSR due to its multiple application
possibilities. The relay can be used for resistive, inductive and capacitive loads. The zero switching relay switches ON when the
sinusoidal curve crosses zero and switches OFF when the
current crosses zero. The instant-on relay with DC control input can be used for phase control. The built- in varistor secures transient
protection for the heavy industrial applications, and the LED indicates the status of the control input. The clip- on cover is securing touch protection to IP 20. Protected output terminals can handle cables up to 16mm2

FAQs of 4-20 mAmps Solid State Relay:
Q: How does the 420 mA Solid State Relay improve industrial automation processes?
A: The solid state relay enables precise and rapid switching of AC loads in response to an industry-standard 420 mA control signal, optimizing process control, enhancing reliability, and reducing maintenance due to its lack of moving parts.
Q: What types of loads are suitable for this solid state relay?
A: This relay is designed for switching resistive loads (like heaters and lights) and moderate inductive loads (such as small motors) up to 10A at 220V AC. It is ideal for applications in industrial automation and process control environments.
Q: When is the best occasion to use a zero-cross trigger SSR in process applications?
A: Zero-cross trigger SSRs are best used when you need to minimize electrical noise and voltage spikes during switching, which is crucial in environments with sensitive equipment and when handling large resistive or moderate inductive loads.
Q: Where can this relay be mounted for optimal use?
A: This solid state relay can be mounted easily on DIN rails or flat panels, fitting into standard industrial enclosures for both new and retrofit installations across manufacturing facilities, PLC cabinets, and process control panels.
Q: What is the process for wiring the 420 mA input and the AC output?
A: Connect the input terminals to your process controllers 420 mA current loop, ensuring polarity is correct. The AC load should be wired to the output terminals, taking care to observe the specified voltage and current ratings. Use screw terminals for secure connections.
Q: How does photocoupler isolation benefit systems using this relay?
A: Photocoupler isolation separates the low-voltage control side from the high-voltage load side, reducing the risk of electrical interference and protecting sensitive PLC or control electronics from voltage transients and surges.
Q: What advantages does this SSR offer over traditional electromagnetic relays?
A: Unlike mechanical relays, this SSR has no moving parts, providing faster response (10 ms), silent operation, extended lifespan, excellent resistance to vibration, and lower maintenancemaking it highly dependable for continuous industrial use.
