Specialty Relays SCE Series, Specification Grade Discrete Plug-in, True Off-Delay Time Delay Relay Product Facts n True Off-Delay timing modes n Six time delays from 0.1 sec. to 10 min. n 10A SPDT or 5A DPDT output contacts n Excellent repeat accuracy — typically better than ±1% n 8-pin octal plug. n File E15631, File LR51332 R R .60 (15) 1.97 (50) CAUTION: If unit has not been energized for several months, apply operating voltage for 20 minutes prior to initial time delay. Accuracy — Repeat Accuracy — ±1 Overall Accuracy — ±5% Reset Time — 30 ms. min. Relay Operate Time — 30 ms. Timing Specifications Contact Data @ 25°C Timing Modes — True Off-Delay — Upon application of operating voltage (min. 100ms), output relay contacts transfer. When operating voltage is removed, the time delay period is initiated. At the end of the delay period, output relay contacts release. If operating voltage is reapplied prior to expiration of the delay period, the delay will be cancelled and output relay contacts will remain transferred. Timing Ranges — 0.1 to 3 / 0.5 to 15 / 1 to 30 / 4 to 120 / 10 to 300 sec.; 0.33 to 10 min. Timing Adjustment — Knob adjustment — Internal potentiometer with external knob adjustment. Maximum time calibrated with +10%, – 0% of values shown below at rated voltage, at 68°F. Fixed time — internal fixed resistor. Arrangements — 1 Form C (SPDT) and 2 Form C (DPDT) Rating — 1 Form C — 10A @ 120/240VAC, resistive; 1/3 HP @ 120VAC; 345VA @ 120VAC; 1/4 HP @ 240VAC; 275VA @ 240VAC. Same polarity. 2 Form C — 5A @ 28VDC or 120/240VAC, resistive; 1/6 HP @ 120/240VAC; 200VA @ 120/240VAC. Same polarity. Expected Mechanical Life — 10 million operations Expected Electrical Life — 200,000 operations, min., at rated resistive load Initial Dielectric Strength — Between Terminals and Case and relay contacts and active circuitry — 1,480VAC for one minute Users should thoroughly review the technical data before selecting a product part number. It is recommended that user also seek out the pertinent approvals files of the agencies/laboratories and review them to ensure the product meets the requirements for a given application. 3.25 (83) Ordering Information SCE | 1.97 (50) Environmental Data Temperature Range — Storage — -40°C to +85°C Operating — -30°C to +65°C Mechanical Data Mounting/Termination — 8-pin octal plug fits either 27E122 or 27E891 (snap-on) socket (order separately) Weight — 4 oz.
