Monitoring Relays

 

Are you looking for voltage, current or light monitoring relays to suit your control application? Here at Fastron Electronics, we provide several types of monitoring relays from Crouzet Automation and Iskra Systemi to meet your needs.

Voltage monitoring relays respond to abnormal or pre-programmed conditions. Typically, they operate when phase supply is lost or when there has been a sequence reversal. As leaders in automation and control, Crouzet have provided their solutions across a range of industries – from Aerospace to Defence, Electrical to Access Control.

We are confident that these products can meet your voltage monitoring relay needs.

Fastron Electronics stocks only a limited range of monitoring relays based on market demand. If you are interested in any other monitoring relay products, please contact us today. We will provide availability and pricing information for any product not currently in stock.

Alternatively, shop online today for the products on this page and enjoy free shipping on all purchases over $300AUD.
