H2-ERM100 vs Moxa Remote I/O Lot: Single Module or Whole I/O Set?

The Automation Direct H2-ERM100 is a low-cost, open-box single Ethernet remote I/O module for DirectLogic DL205 CPUs; the Moxa Industrial Remote I/O Module Lot is a used, multi-module set for bigger systems. Choose the one that matches your cabinet.

Last updated Aug 15, 2026

If you are shopping for control cables, connectors, and I/O hardware, one of the first choices is whether to buy a networked remote I/O module or a used lot of I/O modules. The Automation Direct H2-ERM100 is one remote I/O module for the DirectLogic DL205 family. The Moxa Industrial Remote I/O Module Lot is a used collection of I/O hardware. The listed prices are $590 apart, at $159.00 for the Automation Direct module and $749.00 for the Moxa lot.

Quick verdict

Choose the Automation Direct H2-ERM100 if you already run a DirectLogic DL205 CPU and just need a remote I/O module. Choose the Moxa Industrial Remote I/O Module Lot if you need a multi-module set with different I/O types in one purchase. The Automation Direct module is the more focused option; the Moxa lot gives you more hardware variety, but it carries used-lot risk.

Where each product wins

The Automation Direct H2-ERM100 wins when you want a lower-cost, focused module for a DirectLogic DL205 CPU. Its compatibility list includes several D2-2xx CPUs plus the Do-more H2 series, so it is a convenient single-module route into that PLC family.

The Moxa lot wins when you need to cover multiple I/O types in one order. Instead of buying separate modules one at a time, this lot bundles several I/O types into a single used set.

Automation Direct H2-ERM100 DirectLogic DL205 Remote I/O Module

This is a single remote I/O module aimed at the DirectLogic DL205 family. It has one 10/100Base-T Ethernet port, and the compatibility list includes the D2-240, D2-250, D2-250-1, D2-260, D2-262, and Do-more H2 series CPUs. That gives you a direct way to add a remote I/O link to an existing DL205 cabinet. The new-open-box condition is a plus when you want a more predictable module than a used pull. The main limitation is that it is not compatible with the D2-230 CPU. Also, because this is a single module with one Ethernet port, it is best treated as the networking piece of a larger setup rather than a bundled I/O assortment.

Moxa Industrial Remote I/O Module Lot

This used lot is essentially a spare I/O kit. It includes one Moxa M-4410 analog output module, one M-3810 RTD temperature input module, six M-1800 digital input modules, four M-2801 relay output modules, and two M-7002 field power distributor modules. Supporting parts include a Phoenix Contact QUINT-DIODE/12-24DC/2x20/1x40, a Crydom A2425 solid-state relay, and two Eaton Bussmann DIN rail fuse holders. That range makes it a practical choice if you are building or restocking a distributed I/O cabinet and need more than one type of signal. The limitation is that the modules were removed from an automation cabinet and have not been tested since removal. They were working when removed and look clean, but the lot is sold as shown, so you are accepting the risk of untested used hardware.

Final choice by use case

If you are outfitting a DirectLogic DL205 control cabinet, the Automation Direct H2-ERM100 is the more focused buy. If you are expanding a distributed I/O setup and want a broader module collection in one order, the Moxa Industrial Remote I/O Module Lot is the practical route. Match the choice to the size and signal mix of the cabinet you are working on.
