Check up to five results to perform an action.

High Density Mounting Design Incorporating Ultra-High Reliability Relays Ideally Used as I/O Relay Units for Micromputer Boards, PC and NC Control Boards

Features
  1. 4, 8, 10 and 16 contacts per unit, high density mounting design.
  2. Can be energized using TTL electronic level signals or open collector input.
  3. Also available in a photocoupler isolation type.
  4. Minimum space needed due to compact size.
  5. Provided with operational display (LED).
  6. Incorporated features of the relay units:
    • Hermetically sealed contacts assure high long-term reliability even in adverse environments.
    • Large-capacity switching permits direct switching of large magnetic contactors, DC solenoid valves, etc.
    • Surgeless switching The unique breaking mechanism minimizes surge when magnetic coil is opened.
