DN-SSR4/DN-SSR4DC
4-channel AC-type Form-A Solid State Relay module
 
 
Model: DN-SSR4 Model: DN-SSR4DC
 
  • 4 optically isolated digital output channels
  • 4 Form A solid-state relays
  • Switch up to 4A at 240 VAC (DN-SSR)
  • Switch up to 4A at 50 VDC (DN-SSR-DC)
  • 2,500 V optical isolation
  • LEDs indicate relay status
  • Screw terminal for easy field wiring
  • Build-in diodes to protect from wrong connection of external power supply.
  • Connects directly to ICP CON I-7000 modules, or ISO-730 isolated output board, ISO-C64 output board, ISO-P32C32…etc.
  • DIN-Rail mounting
 
The DN-SSR4 relay module can control high voltage load up to 4 A @ 240 VAC, while the DN-SSR4-DC can control DC voltage load up to 4 A @ 50 VDC. Four indicator LEDs, one for each relay, light when their associated relay is activated. Each output of DN-SSR4 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.
 
  • On/off control
  • Energy management
  • Test Automation
  • Process Control
