Learn why relays should be used with surge protection devices. Discover how surge suppression protects relay contacts, PLC outputs, and improves reliability in industrial automation systems.

Learn what terminal blocks are, what they replace, and why they are essential for industrial control panels. Discover the advantages of RY-ELE PT, ST, and UK terminal block solutions.

RUK and RUT terminal blocks are key to reliable control panel wiring. RUK screw feed-through terminals provide high-current stability and flexible rewiring, while RUT push-in terminals enable fast tool-free signal connections and compact layouts. RY-ELE delivers both series with strong vibration resistance, clear marking, secure clamping, and optimized cabinet space for safer, maintainable automation systems.

Discover the difference between Push-in (RPT Series) and Feed-through (RST Series) terminal blocks from RY-ELE. Learn how each connection technology delivers reliable, safe, and efficient wiring for modern control panels—helping engineers improve installation speed, vibration resistance, and long-term system performance.
