TCR-Relay

Reed Relay, pin compatible to electro-mechanical standard PC-relay with 2 change over switches

The TCR Relay series was designed to replace the electro-mechanical 16-pin Dual-in-Line relays in telecom applications. The relays are 100% pin compatible. TCR Relays are available with dry reed switches as well as mercury-wetted switches (form A).

  • Sealed with epoxy resin
  • Highest reliability
  • Up to 4.25 kVDC isolation voltage
  • Washable
