When you're working on control cables, connectors, and I/O, the buying decision usually starts with a simple question: do you need to move data back to a controller, or do you need to make a physical cable connection that won't fail? The AUTOMATION DIRECT H2-ERM100 / H2ERM100 DirectLOGIC DL205 remote I/O module and the CNLINKO LP-16 3-Pin Industrial Connector Kit - 10 Complete Sets - New sit on different sides of that workflow. This head-to-head compares them by price, function, and the jobs they actually do.
Quick Verdict
If you need to add remote I/O to a DirectLOGIC DL205 system, the AUTOMATION DIRECT H2-ERM100 is the module that fits that slot. If you need sealed 3-pin connections across multiple cable runs, the CNLINKO LP-16 kit gives you a batch of connectors in one purchase. They are complementary rather than interchangeable, so your choice comes down to whether the missing piece is network I/O or physical wiring.

Where Each Product Wins
Where the Automation Direct H2-ERM100 Wins
- It brings remote I/O to a DirectLOGIC DL205 system when the I/O needs to live away from the CPU rack.
- It lists support for D2-240, D2-250, D2-250-1, D2-260, D2-262, and Do-more H2 series CPUs.
- The module is built specifically for this link, so it fits cleanly into a DL205/Do-more H2 control setup.
Where the CNLINKO LP-16 Wins
- At $120, it costs $39 less than the module, which matters if your project is mostly wiring rather than networking.
- The IP67 rating makes it a practical choice for connections that may see water or dust.
- The kit quantity is useful when you have several cable runs to finish at once.
Product Notes
AUTOMATION DIRECT H2-ERM100 / H2ERM100 DirectLOGIC DL205 remote I/O module
This module is built around a single Ethernet 10/100Base-T port that connects a DirectLOGIC DL205 system to remote I/O. It lists support for D2-240, D2-250, D2-250-1, D2-260, D2-262, and Do-more H2 series CPUs, so it works with a defined group of controllers. If you already run one of those CPUs and need I/O in another enclosure, this is the purpose-built part for that link. The main catch is compatibility: it is not compatible with D2-230 CPUs or H2-WPLCx-xx. The unit is new but sold as open box, which can matter if you expect a sealed retail package.
CNLINKO LP-16 3-Pin Industrial Connector Kit - 10 Complete Sets - New
This kit is aimed at cable connections that need to hold up in tough spots. The plug housings are plastic, the sockets are metal, and the reverse-keyed design helps keep certain 3-pin sockets from mating with the wrong plug. It uses solder termination, which means assembly happens at the wire rather than through a network connection. Typical uses include LED lighting, audio/visual equipment, and industrial power, so it fits jobs where a keyed 3-pin connection matters more than data transfer. Choose it when you need to stock a batch of connectors for multiple field connections and want the extra security of reverse keying. The trade-off is that it does nothing for remote I/O or control networking; it handles the physical wiring between components.
Final Choice by Use Case
- If your control system is a DirectLOGIC DL205 or Do-more H2 with a supported CPU, and you need networked remote I/O away from the main rack, go with the AUTOMATION DIRECT H2-ERM100 / H2ERM100 DirectLOGIC DL205 remote I/O module.
- If you're wiring field devices and need sealed 3-pin connections with the flexibility of a multi-pair kit, go with the CNLINKO LP-16 3-Pin Industrial Connector Kit - 10 Complete Sets - New.
- If the project calls for both, the two products work together: the module brings networked I/O onto your control system, and the connectors protect the individual cable connections.
