4 Channel DIN-Rail Solid State Relay Module  

 
 
 
DN-SSR4
4-Channel DIN-Rail Mounting Solid State Relay Module
 
 
 
Functional Description

The DN-SSR4 includes 4 normally open, Form A , solid-state relays. The user can use the DN-SSR4 to switch high voltage load, up to 240VAC and up to 4A. Four enunicator LEDs, one for each relay, light when their associated relay is activated.

Each output equipped with a varistor that shunts the surge voltage of the inductive load or electromagnetic brake to protect the relay contact point. All relay control and relay outputs are accessible through the wiring terminals.
