Description 
Solid State Relays are designed for controlling 
large amounts of power with a Logic Input  
Signal.  
The internal circuit features a dual SCR  
design for full wave capability and a Zero 
Crossing Detector.  
An opto-coupler isolates the input signal from 
the power circuit. 
All Thermolec’s solid state relays are equipped 
with the TransAX™ system that protects 
against transients even on 600V lines, 
therefore ensuring quality, reliability and  
superior performances.
