When you're wiring or repairing an industrial control panel, you often need a switching component that fits a specific job. In the relays, contactors, and industrial switches category, two very different options are facing off: the AMS 4419 Rev G is an industrial control relay PCB, while the Modern Power AC Contactor is a motor starter relay. Both have a place, but they answer different questions. Here's how to choose.
Quick Verdict
The Modern Power AC Contactor is the one to buy if you need a functioning component for motor switching. It's $16.91. The AMS 4419 Rev G is a specific industrial relay PCB priced at $79.00. If your repair route depends on that exact board, the AMS is the one to inspect first; if it doesn't, the contactor is the safer spend.
At a Glance
| Consideration | AMS 4419 Rev G Relay PCB | Modern Power AC Contactor |
| Price | $79.00 | $16.91 |
| Condition | For parts or not working | New |
| Type | Industrial control relay PCB | Power AC contactor / motor starter relay |
Where Each Product Wins
AMS 4419 Rev G wins if your project is a repair that centers on that exact relay board. It's a PCB with specific markings, not a general-purpose contactor. The trade-off is that it's a non-functional, untested board, so it suits someone who can troubleshoot components.
Modern Power AC Contactor wins if you want a contactor to control motors or act as a main power switch. It's built for 110V with an 18A working current and includes auxiliary contacts for momentary-button setups.
Product Notes
AMS 4419 Rev G Industrial Control Relay PCB CN8-A 82350 V1.06
The AMS 4419 Rev G is a specific industrial control relay PCB, identified by the Rev G, CN8-A, and 82350 V1.06 markings. It's a niche part for someone who needs that exact board, not a general-purpose switch. The board is sold as-is for parts or repair, with no guarantee it functions, so it's a project piece rather than a drop-in solution. If you're comfortable inspecting printed circuit boards, checking traces, and working with non-functional components, this gives you the exact base for that work. The limitation is condition: it's untested, may have dust or scratches from previous use, and is not a working relay out of the box. It's an investment in a specific repair path.
Modern Power AC Contactor AC110V 50/60Hz Motor Starter Relay 18A Working Current
The Modern Power AC Contactor is a new power contactor made for 110V applications, with an 18A working current and a motor starter relay function. It's compact, lightweight, and built with plastic housing and a die-casting process, which makes it a practical choice for controlling motors or acting as a main power switch. The built-in auxiliary contacts let it work alongside momentary buttons, so it's more than a simple relay. For a shopper who wants a working component right now, this is the safer route because it's new and not sold as salvage. The limitation is that it can't replace the AMS relay PCB if your panel is built around that specific board. If the task only needs a contactor, this is the one to pick.
Final Choice by Use Case
- You need a contactor for motor switching: Choose the Modern Power AC Contactor.
- You need a specific relay PCB: Choose the AMS 4419 Rev G for that exact board.
- You want the lower-cost option: If the contactor fits, the Modern Power costs less.
