Solid State Relays suit confined space applications.

Press Release Summary:

Measuring 36 x 21 x 24 mm, RF1 Series is designed for control of resistive loads. Zero switching type RF1A switches ON when voltage crosses AC sine wave’s zero crossover point, while instant-ON type RF1B switches ON at instant when control voltage is applied. Relays are rated for up to 25 A load current, up to 280 Vac line voltage, and 5, 12, or 24 Vdc control voltage. Integrated transils protect against over-voltage, while green LED indicates presence of control voltage.

Compact Solid State Relay - Up to 25 Amps

Buffalo Grove, IL — CARLO GAVAZZI is proud to announce the launch of their new RF1 Series Compact Solid State Relay. The RF1 Series provides compact solid state switching suited for applications with confined space. Long lifetime is ensured by CARLO GAVAZZI’s new assembly technology that significantly reduces stresses of the power semiconductor. The RF1 Series is ideally suited for applications where trouble free operation is required for a large number of cycles and where space is limited. The RF1 Series occupies only 30% of the panel space typically required for a typical panel mounted (hockey puck) solid state relays, it’s merely 36 x 21 x 24mm (H x W x D).

The RF1 Series is designed for control of resistive loads. The zero switching type (RF1A), switches ON when the voltage crosses the AC sine wave’s zero crossover point. The instant-ON type (RF1B), switches on at the instant when control voltage is applied. Integrated transils provide protection against over-voltage. A green LED indicates the presence of control voltage. Fast-on terminals for the input and output voltage enable fast and secure installation. The RF1 Series is provided with a convenient pre-attached thermal pad, making it ready for mounting on a panel or heat sink.

• Up to 280VAC line voltage

• 5, 12 or 24VDC control voltage

• Up to 25A load current

• Zero crossing or Instant-on switching

• Transils for over protection

• LED status indication

• CE mark and cRUus CSA and VDE approvals

• UL508 100K cycles endurance rating

The RF1 Series are available from Carlo Gavazzi’s North American network of sales offices and distributors, or at
