[MITSUBISHI ELECTRIC] — SR-T DL Delayed-Release Auxiliary Relay (T5/T9 Frame, AC100V/AC200V)
Family ID: MEL-SR-DL
Mitsubishi Electric SR-T5DL and SR-T9DL delayed-release auxiliary relays. A capacitor holds the relay closed for 2 (+2/-1) seconds against momentary power failures and voltage dips caused by lightning strikes, preventing unintended dropout. Effective contact arrangements: 2a1b (T5DL), 6a1b and 4a3b (T9DL). Operating coils available in AC100V and AC200V only. Dedicated AC-operated relay-capacitor assemblies; the relay alone cannot be replaced. Electrolytic capacitor requires periodic verification of the holding time. Conforms to JIS C8201-5-1, IEC 60947-5-1, EN 60947-5-1, GB14048.5. IEC 35mm rail mounting.
