When you're picking Ethernet remote I/O for a control cabinet, the first decision is usually compatibility: do you need a module that fits a specific PLC family, or do you want a Moxa Ethernet remote I/O module that keeps the project cost in check? This head-to-head compares the Automation Direct H2-ERM100 DirectLOGIC DL205 remote I/O module with the Moxa ioLogik E1242-T and two different compatibility approaches. The trade-off is straightforward: one module is tied to a clearly named CPU family, while the other is a Moxa Ethernet remote I/O module that you evaluate on its own specs.
Quick verdict
Pick the H2-ERM100 if you need a DirectLOGIC DL205 Ethernet remote I/O module and your CPU is one of the supported models: D2-240, D2-250, D2-250-1, D2-260, D2-262, or a Do-more H2 series CPU. This module names its CPU family up front, which makes the selection process more direct. Pick the Moxa ioLogik E1242-T if you want a Moxa Ethernet remote I/O module and are not tied to the DirectLOGIC CPU match. The Moxa is the one to evaluate on its own specs when your control system is not built around DirectLOGIC.
Comparison at a glance
| Product | Listed price | Main strength | Price bar |
|---|---|---|---|
| Automation Direct H2-ERM100 DirectLOGIC DL205 remote I/O module | USD 159.00 | DirectLOGIC DL205 compatibility with one 10/100Base-T Ethernet port | |
| Moxa ioLogik E1242-T Ethernet Remote I/O Module | USD 110.00 | Moxa Ethernet remote I/O with 12-36 VDC input |
Where each product wins
- H2-ERM100: Best when your control system is DirectLOGIC DL205-based and you want a module that names its supported CPUs. If you already run a supported D2 or Do-more H2 series CPU, this is the module that is explicitly described as the match for that family.
- Moxa ioLogik E1242-T: Best when you are looking for a Moxa Ethernet remote I/O module and the DirectLOGIC compatibility list is not part of your decision.
Product notes
Automation Direct H2-ERM100 DirectLOGIC DL205 remote I/O module
If your control system is built around a DirectLOGIC DL205 CPU, the H2-ERM100 removes a lot of guesswork. It is specified for use with D2-240, D2-250, D2-250-1, D2-260, D2-262, and Do-more H2 series CPUs, so you can confirm fit against your exact CPU model before you commit. The module has one 10/100Base-T Ethernet port for the remote link. The trade-off is that compatibility is narrow: the D2-230 CPU and H2-WPLCx-xx are not supported, so those installations need a different path. It is also a new open-box unit, so the condition is part of the buying decision. For the right DirectLOGIC owner, the clear CPU match is the main reason to choose it.
Moxa ioLogik E1242-T Ethernet Remote I/O Module
The Moxa ioLogik E1242-T spells out its power input in the title: 12-36 VDC. If your panel already runs at a voltage in that band, the module is easier to slot in. It is a good candidate when you want a Moxa Ethernet remote I/O module and are not looking for a DirectLOGIC-specific part. The unit itself is new, but the original box was discarded, so this is an open-box purchase without the retail packaging. That packaging trade-off may matter if you expect a sealed box. For shoppers who need a Moxa Ethernet remote I/O module and are flexible about original packaging, the 12-36 VDC input and the new unit are the main draws.
Final choice by use case
For a DirectLOGIC DL205 system: Choose the Automation Direct H2-ERM100 at USD 159.00. The direct CPU compatibility is the reason to take the higher price; you are paying for a module that is explicitly matched to your processor family.
For a Moxa Ethernet remote I/O module: Choose the Moxa ioLogik E1242-T at USD 110.00. It is the lower-priced way to get a Moxa Ethernet remote I/O module in this comparison, and it works best when DirectLOGIC compatibility is not the deciding factor.
