Control Relay - 905

Brand: WIKA Alexander Wiegand SE & Co. KG
Request Information
Contact protection relays are used in type 821 contact devices. They increase the switching reliability and switching capacity of electromechanical contact devices and lower their contact voltage.

Undesired switching operations of contact devices caused by vibrations are significantly reduced by a drop-out delay of 0.5 sec.
Features
  • 905.12 for 1 contact, output: 1 x SPDT. 
  • 905.13 for 2 contacts, output: 2 x SPDT. 
  • 905.14 for 2 contacts, output: 1 x SPDT intermittent, e.g. for pump control. 
  • Power supply 230Vac - 45.. 60Hz - 2,5VA. 
  • Electrical rating: 250Vac/8A/1840VA (min. 24Vdc/0,1A). 
  • Drop out delay: 500ms. 
  • Auxiliary output: 24Vdc - 20mA. 
  • Ambient temperature 0.. +70°C. 
  • Ingressprotection IP 40 (terminals IP 20). 
  • Hat rail mounting.
