A breakthrough in low cost photocell technology that includes an electro-magnetic relay and a photodiode sensor that reduces burning hours, lowers power consumption and ensures lifetime switching accuracy. The electronic circuit in the SS4ED delivers extremely accurate and reliable switching control. Also includes a VDR (Voltage Dependent resistor) as standard, protecting the circuit from high transient voltages. Both the SS4D and SS4ED are available as a 'Kit' (with socket & Bracket) or a 'cell only.
