Crydom SeriesOne DR Timer DIN-Rail Time-Delay Solid-State Relay

Crydom SeriesOne DR Timer solid-state relays (SSR-switches without moving contacts) are modules for 35 mm DIN rail with an integrated timing function and status LED. The output is 24–280 V AC (47–440 Hz) or 1–48 V DC, rated at 6 A-for example DRTA24D06R for an AC output and DRTL06D06 for DC.

Control voltage is 12–24, 90–140 or 180–240 V AC/DC. Switching-surge withstand is 600 V for AC outputs and 60 V for DC; permissible surge current is 285/300 A for one AC cycle and 60 A for DC. Operating temperature is −30 to +80 °C. Approvals: UL product approval, IEC 60947, IEC 62314, CE and RoHS.

In rolling stock, they are used for contactless delayed switching of auxiliary circuits and sequencing without a separate time relay.
