Reliable Switching and Coil Protection for Industrial Automation
Electromagnetic relays such as the Finder 55.34.9.110.0080 enable electrical control signals to operate multiple independent circuits while maintaining electrical isolation between the coil and contact circuits. When the 110 V DC coil is energised, the relay switches its four changeover contacts, allowing connected equipment to respond to the control signal.
The integrated LED indicator and protective diode provide additional functionality for industrial control systems. The LED allows maintenance engineers to identify when the coil is energised, while the diode suppresses the voltage transient generated when the coil is switched off. Because the diode is polarity-sensitive, the positive supply must be connected to terminal A1/13 to ensure correct operation.
The 4PDT contact arrangement is particularly useful where several auxiliary circuits must be switched simultaneously. Combined with its compact plug-in construction and durable AgNi contacts, the Finder Series 55 design offers a practical solution for control cabinet installation, automation system maintenance and electrical switching applications.
Typical Applications
- Industrial automation and machinery control systems.
- PLC output interfacing and control signal switching.
