This is an individual relay in Weidmüller's D-SERIES DRM range, model DRM570548L (Order No. 7760056093), with 4 CO contacts (AgNi flash gold-plated) and a rated control voltage of 48 V AC. On the control side, rated current is 33.3 mA at 50 Hz / 27.8 mA at 60 Hz, power rating 1.0-1.2 VA (60 Hz), coil resistance 615 Ω ±10%, with a red LED status indicator. On the load side, rated switching voltage is 250 V AC, continuous current 5 A, max. switching voltage AC 250 V, inrush current 10 A/50 ms, AC switching capacity (resistive) max. 1250 VA and DC switching capacity (resistive) max. 120 W @ 24 V, with switch-on and switch-off delay both under 20 ms and a mechanical service life of 20 × 10⁶ switching cycles. This version has no test button, but does have a mechanical switch position indicator.

The relay measures 35.7 mm deep, 27.4 mm high and 21 mm wide, weighs 36.2 g, has a transparent housing and connects via plug-in connection. Protection degree is IP20, rated voltage 250 V, pollution severity 2, surge voltage category III, with an impulse withstand voltage of 6 kV (1.2/50 µs). Ambient temperature range is -40°C to 55°C (storage -40°C to 70°C), humidity 35-85% relative, non-condensing. UL94 flammability ratings are V-2 for the cover, V-0 for the baseplate, and HB for the status indicator. The relay carries UL certificate No. E312083 (cURus), is RoHS compliant without exemption, and its REACH declaration states no SVHC above 0.1 wt%.
