3RS18 coupling relays in their proven 22.5 mm industrial enclosure serve to couple control signals from and to a controller.

The series comprises devices with up to three changeover contacts with screw terminals or spring-type terminals as combination voltage or wide voltage range versions.

The relay coils are protected internally with noise suppression diodes.

Versions:

• Wide voltage range: One connection for a wide voltage range
• Combination voltage: Two connections for different voltage ranges
• Versions with solid-state compatible outputs (hard gold-plating)
• 1, 2 or 3 changeover contacts
