Shop plug-in relays for electrical switching, machine control, signal isolation and industrial automation applications. Their removable design allows compatible relays to be installed in sockets for easier wiring, testing, maintenance and replacement.
Wallco supplies plug-in relays from established manufacturers in a range of coil voltages, contact configurations, current ratings, pin arrangements and enclosure styles. Use the available technical filters to compare products and identify a relay compatible with your circuit and relay socket.
Plug-in relays connect to a compatible socket rather than being permanently wired directly into the equipment. This arrangement can simplify panel wiring and allows the relay to be removed for inspection, testing or replacement without disconnecting the field wiring from the socket.
Important selection factors include coil voltage, contact configuration, contact ratings, pin count, terminal arrangement, enclosure style and socket compatibility. Common configurations include octal 8-pin, 11-pin and 14-pin designs, but relays and sockets should always be matched using the manufacturer’s specifications.
Products are organized generically so plug-in relays from different manufacturers can be compared within the same category and technical filters. Compatible sockets and mounting components are available under Relay Sockets & Accessories.
