Relays

Electrically operated switches used to control a high-power circuit with a low-power signal, providing essential electrical isolation and control logic.

Schneider Electric | Harmony (formerly Zelio) Relays

Schneider’s Harmony range is designed for “seamless integration.” They are sourced for their extreme ease of use—featuring integrated test buttons and clear LED indicators that allow maintenance teams to troubleshoot a circuit without even opening a laptop.

Harmony RSL

Model Number: RSL1PRBU

Only 6mm wide; saves 80% cabinet space; 6A capacity; ideal for PLC isolation.

Key Technical Specifications:

  • The ultra-slim 6mm width allows you to pack dozens of relays into a single DIN rail row, perfect for high-density PLC I/O.

  • Often sourced as a complete kit (relay + socket + retaining clip), reducing procurement complexity and assembly time.

  • Optimized for direct control from PLC transistor outputs without requiring additional power amplification.

Harmony RXM

Model Number: RXM2AB2BD

2, 3, or 4 changeover contacts; up to 12A; lockable test button for fast commissioning.

Key Technical Specifications:

  • A mechanical lever allows technicians to manually force the contacts closed to test a circuit, even if the PLC signal is off.

  • Features a built-in mechanical flag and a high-brightness LED to show the switching status in any lighting condition.

  • Available versions with gold plating to ensure reliable switching for low-level signals where oxidation would cause failures.

Finder | 34 & 40 Series Relays

Finder is a dedicated specialist in switching technology. They are often the “sourcing secret” for high-reliability projects because their relays are known for having one of the longest electrical lifespans in the industry. Their 34 and 40 series are the global benchmarks for PCB and socket-mounted relays.

Finder 34 Series

Model Number: 34.51.7.024.0010

Ultra-slim PCB/Socket relay; 6A switching; high-sensitivity DC coils (170mW).

Key Technical Specifications:

  • Provides 6kV (1.2/50 μs) insulation between the coil and contacts, ensuring total safety for sensitive control boards.

  • Optimized mechanical design leads to significantly quieter switching compared to standard industrial relays.

  • Can be soldered directly onto a PCB or plugged into a 93-series socket for easy field replacement on a DIN rail.

Finder 40 Series

Model Number: 40.52.9.024.0000

Up to 16A switching; 1 or 2 CO contacts; available in “sensitive” DC or AC versions.

Key Technical Specifications:

  • The 40.61 variant can handle up to 16A, making it a powerful choice for controlling small motors or solenoid valves directly.

  • Environmentally friendly contact materials (AgNi or AgSnO2) provide high resistance to “welding” during inrush currents.

  • Available with RT III (IP67) environmental protection, allowing the relay to be used in high-humidity or contaminated environments.
