Industrial Solid State Relay it is a new type of non-contact switching device completely composing of solid electric elements. It’s adopts the switching characteristic of high power audion, power field effect tube, one-way and two-way controllable silicon and module to make and break the circuit without contact or spark.


1.input signal could make compute terminal and digital logic circuit compatible.
2.Optical isolation between input and output circuit, with isolating.
3.Withstand voltage of 400V
4.Two specifications: zero-crossing triggering and random triggering.
5.LED indication for working condition.
6.Built-in resistance-capacitance absorption circuit.
7.Dielectric withstanding voltage:>2KV
8.Dielectric insulating strength: >50MΩ
9.Actuation time: ON>10ms/OFF<10ms
10.Working environment: -20℃~+70℃


1. SSR serious solid state relay adopts flame resistant engineering plastic case,epoxy resin encapsulation,screw thread educting terminal connection.

2. With high-strengh structure, impluse resistance,high shock resistance performance,small driving current for input terminal and covenient connection with computer terminal and digital control circuit,

3. The product is widely used in automatization control fields such as petroleum,chemica industry,instrument and meter,pharmacy machine,food machine,packaging machine,textile machine,plastics machine,numerical control lathe,entertainment facility,ect,

4. Especially for severe environment full of corrosion and moisture or requiring explosion-proofand dust resistance or place demanding frequent switching.
