RIU Series I/O Relay Units

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

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.
