Finder 7S.36.9.110.5420 interfacrelais, 6 A, 4 NO + 2 NC, 110 V AC spoel, DIN-rail

Industrial control panels and automation systems often need to switch multiple circuits safely while providing feedback on contact status. The Finder 7S.36.9.110.5420 interface relay is built for such tasks, featuring forcibly guided contacts that prevent simultaneous closure of NO and NC contacts—critical in safety circuits. With a 110 V AC coil and 6 A switching capacity, it handles a wide range of loads. Its DIN rail mounting and 14-pin socket compatibility simplify installation and replacement in existing setups.

Why choose it

Forcibly guided contacts are mandatory in many safety applications, and this relay provides that assurance in a compact, DIN-rail-mountable package. The 4 NO + 2 NC configuration offers flexibility for control and monitoring circuits, while the 6 A rating covers a broad range of industrial loads. Its wide operating temperature range and flux-proof construction ensure reliable performance in demanding environments.

Ideal use cases

• Safety relay modules in machinery
• Interface between PLC outputs and high-power loads
• Elevator control systems
• Railway signaling equipment
• Industrial automation panels

Good to know

The relay is designed for use with a 14-pin socket (not included) for screw terminal connections. It meets international standards and carries CE, UL, CSA, and VDE approvals. The coil operates on 110 V AC, so ensure your control voltage matches. The forcibly guided contact mechanism ensures that all contacts move together, preventing unsafe states.
