Frequently Asked Questions
Is 115 VAC a coil voltage on this relay?
No. The coil is 29 VDC. The 28 VDC and 115 VAC figures are the contact ratings, 2 A at either voltage.
What socket does the 5D1C-1020 plug into?
An 8-pin octal socket. The keyed center post sets the orientation, and the wiring diagram on the cover shows which pins carry the coil and which carry the contacts.
The price per piece steps down with quantity, and the price-break table on this page shows each step.
The octal base began under vacuum tubes, and the relay trade kept it long after the tubes left the panel. Find the empty socket; the keyed post shows which way it goes.
