Protection Relays Single Function Relays and Controls SIR SERIES Solid-State Relay - Isolated Description The SIR Series is designed for industrial applications requiring rugged reliable operation. Provides an optically isolated, high capacity, solid-state output, with power switching capability up to 20A steady state, 200A inrush. Zero voltage switching SIR2 extends the life of an incandescent lamp up to 10 times. Random switching SIR1 is ideal for inductive loads. When fully insulated female terminals are used on the connection wires, the system meets the requirements for touch-proof connections. Operation The solid-state output is located between terminals 1 and 3, and is normally open or normally closed without control voltage applied to terminals 4 and 5. When control voltage is applied to terminals 4 and 5, the solid-state output opens or closes respectively. Reset: Removing control voltage resets the output. The unit is also reset if output voltage is removed. Wiring Diagram Features & Benefits L1 N/L2 FEATURES BENEFITS V = Voltage CV = Control Voltage Compact design L = Load measures 2 in. Perfect for OEM applications where space is limited (50.8mm) square Load may be connected No moving parts to arc and wear out over time and Totally solid state to terminal 3 or 1. encapsulated to protect against shock, vibration and encapsulated and humidity Note: Normally open output is Up to 20A, 200A inrush Provides direct control of heavy inductive, shown. Normally closed output is output rating incandescent or resistive loads also available. Switching output is Provides the ability to interface between 2 different optically isolated from electrical circuits the control input SIR1 models provide Designed for use with resistive and incandescent random switching loads, extending lamp life up to 10 times SIR2 models provide zero Perfect for resistive and incandescent loads voltage switching Metalized Facilitates heat transfer in high current applications mounting surface Ordering Information MODEL SWITCHING CONTROL VOLTAGE RATING OUTPUT FORM OUTPUT VOLTAGE SIR1A1A4 Random 9 to 30VAC or DC 3A Normally open 120VAC SIR1A20A4 Random 9 to 30VAC or DC 20A Normally open 120VAC SIR1B6B4 Random 90 to 150VAC or DC 6A Normally closed 120VAC SIR1C20B6 Random 190 to 290VAC or DC 20A Normally closed 230VAC SIR2A20A4 Zero voltage 9 to 30VAC or DC 20A Normally open 120VAC SIR2B20A4 Zero voltage 90 to 150VAC or DC 20A Normally open 120VAC SIR2B20B4 Zero voltage 90 to 150VAC or DC 20A Normally closed 120VAC If you dont find the part you need, call us for a custom product 800-843-8848 2016 Littelfuse Protection Relays & Controls Rev: 1-A-062716 wwwwww.littelfuse.com/sir.littelfuse.com/Protection Relays Single Function Relays and Controls SIR SERIES Accessories Specifications P1015-13 (AWG 10/12), P1015-64 (AWG 14/16), Output P1015-14 (AWG 18/22) Female Quick Connect Type Optical isolation, totally solid state These 0.25 in.
