Series BS 4A to 250 Vac SIP Package DC Control Part Number Description BS24D4A 4A, 280 Vac BS24D4F 25A, 280 Vac Part Number Explanation BS 24 Series D 4 A Control Range3 Switch Type2 Line Voltage Output Current – Amps 1 NOTES 1) Line Voltage 24 = 280 Vac 2) Switch Type: D = Zero-cross turn-on 3) Control Range: A = 3.0-10 Vdc for BS24D4A; F = 8-30 Vdc FEATURES/BENEFITS • Industry standard package • High in-rush capabilities • Low input current draw • High dv/dt capability MECHANICAL SPECIFICATION 0.01 .02 .39 (10.2) 1.70 (43.2) DESCRIPTION The BS 4-amp solid-state single inline (SIP) four-pin relays are designed for mounting on a printed circuit board. The relays offer built-in voltage protection and can withstand very high current overloads. The Series BS4 relays have a low zero-cross window. The compact size and triac output make the BS relay the perfect retrofit for electromechanical relays. 0.01 .98 (25.4) - + .02 .19 (6.5) .30 (7.63) .49 .001 .40 .001 (12.7) (10.16) .20 .001 (5.08) Ø1 .30 (7.62) WEIGHT: 0.7 oz.
