Datasheet Summary
Powered by GS/AI

The ETPS4H8CD is a 4PDT hermetically sealed relay for rail and aerospace use, measuring 26.0 x 26.0 x 25.7 mm and weighing 77 g. It operates from -70°C to +125°C with a 74 Vdc coil, 1920 Ω resistance, and internal voltage suppression. Contact ratings are 1.3 A resistive and 0.6 A inductive at 74 Vdc, with a mechanical life of 500,000 cycles. Operate time is 15 ms max, release time 15 ms max at +25°C. Dielectric strength is 1,250 Vrms between coil and case initially. Insulation resistance is 100 MΩ min at 500 Vdc. Tin-plated terminals and M3 mounting are standard.
