RXG interface relays
Presentation and description
Presentation of the range

RXG relays are interface plug-in relays with Faston pins for better reliability and robust installation. They are used in PLC applications.

The RXG interface relay range comprises:

1 10 A relays with 1 CO contact and 5 A relays with 2 CO contacts
2 Sockets with separate or mixed contact terminals, built-in plastic maintaining clamp
3 Protection modules (diode, diode + LED, RC circuit, or varistor + LED) for RXG separate sockets
4 Clip-in legends for RXG separate sockets

These relays are available in both pre-assembled (single reference) and customer assembled offers.

Relay description
1 Push button for testing the contacts (blue: DC, red: AC)
2 Mechanical “relay status” indicator
3 Removable lock-down door enabling forced maintaining of the contacts for test sequences or maintenance purposes
4 LED (depending on version) indicating the relay status
5 Removable legend for relay identification
6 5 or 8 Faston type pins
7 Standard cover-type relay with pushbutton, mechanical indicator, and LED options
8 Basic cover-type relay with LED option
