This state-of-the-art solid-state relay  
is designed for use in AC power  
switching applications. The output is  
rated for 1A at 250 Vrms and can  
operate from 40 to 440 Hz for  
resistive and reactive loads with  
power factors as low as 0.2. Back-  
to-back SCRs are configured for  
zero voltage turn-on and can handle  
current surges up to 8A. The  
patented circuit design assures the  
lowest possible EMI by virtually  
eliminating commutation spikes  
while maintaining excellent noise  
immunity. Optical isolation allows  
safe control of AC loads from low  
level logic circuits. The low-profile  
metal DIP package is hermetically
