MDR series 10 Amp Rotary Relay For Demanding Shock & Vibration Applications Small 4PDT Medium 24PDT Features Operate Data 25C Type Typ. Operate Time (ms) Typ. Release Time (ms) AC and DC coils, latching and non-latching. 4PDT through 24PDT contact arrangements. Small AC Non-Latching 5 to 12 5 to 18 Small DC Non-Latching 15 to 30 5 to 15 Contacts will not chatter when relays are subjected to high-impact shock Small AC Latching 6 to 12 N/A blows of 2000 ft.-lbs. Small DC Latching 10 to 16 N/A Medium AC Non-Latching 6 to 12 6 to 20 Medium DC Non-Latching 65 to 90 10 to 30 Contact Data Medium AC Latching 8 to 14 N/A Arrangements: 4 Form C (4PDT) through 24 Form C (24PDT). Medium DC Latching 30 to 80 N/A Contact Ratings Latching Two-Position Types: Except for the latching feature, MDR Single Contacts Two Contacts in Series latching relays utilize the same general construction as non-latching types. They have two sets of coils and provide a latching two-position operation. 10A, 115VAC 3A, 440VAC 3A, 28VDC 15A, 115VAC L M K 0.8A, 125VDC 1.5A, 125VDC 1 3 The above AC contact ratings are based on contact loads having a 50% power factor. The DC Contacts Shown With J A Coil Coil contact ratings are based on resistive loads. Coil 1-2 De-Energized and B H Coil 3-4 Energized. Contact Section G C 2 4 Coils Must be Energized Alternately, F D E Not Simultaneously Environmental Data Temperature Range: Standard models: 0C to +65C. Special order models: 0C to +90C.
