❓ Frequently Asked Questions (FAQs) – DIN Rail Relays for Panel Control

🔧 What is a DIN rail relay?

A DIN rail relay is a compact electrical device that mounts on a standard DIN rail inside a control panel. It’s used for switching, delaying, or monitoring electrical loads in automation and protection systems.

⚡ Do I need a voltage monitor for my panel?

Yes, if you’re protecting sensitive equipment like motors or HVAC systems. Voltage monitors detect overvoltage, undervoltage, or phase faults — helping you avoid costly damage and downtime.

⏱ What’s the difference between a delay-on and delay-off timer?

Delay-on timers (like Niglon DOST) wait before turning a device on.
Delay-off timers (like Niglon TDOT) keep a device on after it’s switched off (useful for extractor fans or cooling circuits).

🧰 Are these Niglon relays compliant with BS 7671?

Yes. All listed Niglon DIN rail devices are suitable for installations under BS 7671 (18th Edition) wiring regulations. They are commonly used in compliant UK panel builds.

🔄 Can I mix and match these timers and monitors in the same panel?

Absolutely. These devices are all DIN rail-mounted with standard 17.5 mm widths and are designed to work together in multi-function panels.
