**Description**

S–240/480-..-AA/BB/CC–08/12 is an analog single phase solid state relay from Satronix. The analog or phase angle control relay is meant for resistive loads. It controls the load linearly (0-100%) on receiving I/P from PID. It has 3 control input options of 4-20mA or 0-10VDC or 0-5 VDC. Offered upto operational voltage range of 600 VACrms and operational current options of 10, 25, 50, 75, 90 A. It has LED indication for current. Ideal for Tungsten Lamp dimming, Resistive Heating Control, and Universal Motor Control and many more applications
