Frequently Asked Questions

What type of contacts does the G7S-4A2B-E relay have?

The G7S-4A2B-E relay features forcibly guided contacts, which means that the contacts are mechanically linked to ensure that when one contact is in the open position, the other is in the closed position. This relay configuration includes 4PST-NO (Pole Single Throw, Normally Open) and DPST-NC (Double Pole Single Throw, Normally Closed) contacts.

Can this relay be used in safety circuits?

Yes, the G7S-4A2B-E relay is designed with forcibly guided contacts that make it suitable for use in safety-related control systems. Its contacts follow the guidelines of EN50205 Class A, which is a standard for relays with mechanically linked contacts used in safety applications.

What is the switching capacity of the G7S-4A2B-E relay?

The G7S-4A2B-E relay has a high switching capacity, with NO contacts rated for 10 A at 250 VAC or 30 VDC, and NC contacts rated for 6 A at 250 VAC or 30 VDC.
