Coil voltage, contacts and mounting decide the fit
Coil voltage first, then contact arrangement, then the socket or rail it mounts on. Get those three right and a relay is one of the easier swaps in a panel. Stock here has included Minimax FMZ5000 eight-relay modules and an electropneumatic on-delay timing relay with a 1-10 minute adjustable range on a 125 V DC coil.
Timing relays add two more variables, the timing function and the adjustment range, both normally printed on the case. Since this inventory is surplus and turns over daily, checking back counts for as much as searching once. Wider panel components are listed under electrical, and anything absent can be sourced on request.
Our team can locate, cross-reference, and source all parts.
