Frequently Asked Questions

Q: What is the difference between the SSR-41FDD and SSR-41FDA models?

A: The SSR-41FDD is a DC-to-DC solid state relay, switching a DC load (5–60V DC) with a DC control signal (3–32V DC). The SSR-41FDA is a DC-to-AC solid state relay, switching an AC load (24–250V AC) with the same DC control signal (3–32V DC). Choose based on whether your load is DC or AC powered.

Q: How do I install this solid state relay on a DIN rail?

A: Simply align the module's built-in DIN rail clip with a standard 35mm DIN rail and snap it into place — no screws or additional hardware required. The slim profile allows side-by-side installation of multiple relays in compact control panels.

Q: Is this SSR relay suitable for PLC and automation control systems?

A: Yes. The 3–32V DC control input is fully compatible with most PLC output signals. Its non-contact SSR technology ensures fast, noise-free switching — making it a reliable choice for industrial automation, home automation, temperature control, and other switching applications.

Q: What load can this relay handle?

A: This relay supports a maximum load current of 6A. It is designed for controlling DC loads up to 60V DC or AC loads up to 250V AC, depending on the model variant selected. Always ensure your load specifications do not exceed these ratings.
