Doosan 301202-00067 is the 24 V power relay: the plated steel coil can marked 24V on a slotted mounting bracket, and the black terminal block with two large copper main studs and two small screw terminals for the coil. It is used on Doosan Daewoo excavators. This aftermarket version has the same mounting and electrical connector as the original, so it plugs in and bolts on where the old one came off.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

Function dead with good fuses
A starter, glow plug or fuel relay that has burned its contacts stops the circuit without blowing a fuse.
Clicking but no power
A relay that clicks but does not pass current has worn contacts and needs replacing.
Heat and vibration
Relays near the engine wear out from heat and vibration. Swap them during major services.
Fleet spares
Relays are cheap to keep on the van and quick to change on site.

Yes, it was made for the Doosan Daewoo DX140W, and 5 more listed under compatible equipment. Check the old relay is marked 301202-00067 or one of the cross references, because makers change parts between serial ranges.
On the Doosan Daewoo DX140W, there is no fixed interval. It is changed when it fails, and many fail from water in the plug or chafed wiring rather than wear.
A fault code for this circuit, readings that jump or stay fixed, or a part that does not respond with power at the plug.
Read the fault codes, then check the plug and wiring for corrosion or a broken wire. A wiring fault reads the same as a failed relay.
Usually. Clear them after fitting and run the machine, so old codes are not mistaken for a new fault.
No. It is an aftermarket relay made to replace the Doosan 301202-00067. It is not made by the original manufacturer; the number only shows what it replaces.
