Which part belongs in your control panel? In the relays, contactors, and industrial switches aisle, you're choosing between two very different repairs: one is a board-level control relay PCB, the other is a reversing motor starter that bundles multiple components. Both sit close to $80, but they solve different problems.
Quick verdict
If you need a reversing motor starter, the AB 100-C09*10 is the more complete buy and costs less than the AMS board. It includes the 120V coil reversing contactor, overload protection, and the connector wire between contactors. The AMS 4419 Rev G is a single used PCB sold as-is for parts or repair, and it is untested. The roughly $4 spread makes the price difference small, but the gap in what you can expect from each part is large.
At a glance
| Product | Listed price | Price bar | Condition | What's included |
|---|---|---|---|---|
| AMS 4419 Rev G Industrial Control Relay PCB CN8-A 82350 V1.06 | $79.00 | For parts or not working | One used, untested circuit board | |
| AB 100-C09*10 Reversing motor starter Contactor 1.6/5A overload relay 120V Coil | $74.99 | Used | Reversing contactor set with overload relay |
Where each product wins
Where the AMS 4419 Rev G wins: It matches a specific board designation. If your board-level repair needs the AMS 4419 Rev G layout or the CN8-A 82350 V1.06 identifier, this listing gives you that exact PCB.
**Where the AB 100-C09*10 wins:** It gives you a more complete reversing starter package at the lower listed price, so you don't have to source separate pieces for the starter.
Product notes
AMS 4419 Rev G control relay PCB

This single used circuit board is listed at $79.00. It's a direct match for the AMS 4419 Rev G designation with the CN8-A 82350 V1.06 identifier, so if your panel or equipment accepts this board, it's the specific spare to source. The limitation is condition: the board has not been powered on or functionally tested, it's sold AS-IS, and there is no guarantee of functionality or compatibility. You may also see minor cosmetic wear like dust, scratches, labels, or wiring from previous use. Treat it as a parts board unless you can confirm it works in your circuit.
AB 100-C09*10 reversing motor starter

This used reversing motor starter is listed at $74.99 and brings the core components together: a 120V coil reversing contactor, a 1.6/5A overload relay, and the connector wire between contactors. That's a practical bundle if you're rebuilding a reversing starter, because you won't need to track down the relay and connecting wire separately. The model is 193-EA1EB and the MPN is 100-C09D10, so you can compare those numbers with your current starter. The trade-off is that it's used, so inspect the contactor and overload relay carefully before wiring them into your panel. For a complete reversing motor starter replacement, this is the stronger choice in this pairing.
Final choice by use case
Choose the AB 100-C09*10 reversing motor starter when your job is a reversing contactor with overload protection. It's the more complete bundle, and it comes in at the lower listed price.
Choose the AMS 4419 Rev G control relay PCB when your repair specifically calls for the CN8-A 82350 V1.06 board and you're comfortable working with an as-is, untested parts board. It's the matching spare for that exact designation.
