Choosing between the AutomationDirect H2-ERM100 and the Lapp Epic 10.1710 starts with one question: are you adding a remote I/O link to a control system, or are you terminating a control cable? These two industrial components serve very different jobs, and their list prices reflect that. The H2-ERM100 is a DirectLOGIC DL205 remote I/O module. The Lapp Epic is a connector receptacle. Neither replaces the other; your choice depends on whether your next step is data or wiring. The right pick comes down to your existing PLC family, your wiring plan, and the budget you've set for this piece.
Quick verdict
Choose the H2-ERM100 for a compatible DL205 or Do-more H2 system when you need to add remote I/O to your rack. Choose the Lapp Epic 10.1710 when your next step is a physical control connection. The module is the higher-priced of the two; the receptacle is the lower-priced option. If your control panel is already built around the DL205 family, the module is the one that adds capability. If you're just making the connections, the receptacle is the more direct purchase.

Where each product wins
The H2-ERM100 fits applications that expand I/O capabilities over a network. The Lapp Epic fits applications that need an industrial connector for wiring. If your focus is communication and control expansion, the module is the right direction. If your focus is a solid physical connection at the panel, the receptacle is the right direction. The module's job is to bring remote I/O back to the processor; the receptacle's job is to give the wiring a defined, secure termination point.
Product notes
AutomationDirect H2-ERM100
The H2-ERM100 is a DirectLOGIC DL205 remote I/O module with one Ethernet 10/100Base-T port. It's sold as new open box. If your control system uses a D2-240, D2-250, D2-250-1, D2-260, D2-262, or Do-more H2 series CPU, this module is built for that family. The limiting factor is CPU compatibility: it won't work with the D2-230 or H2-WPLCx-xx. So the reason to choose it is the Ethernet remote I/O capability; the reason to look elsewhere is an older processor not on that list. For a system already running one of those CPUs, the module gives you a straightforward way to bring a remote rack onto the network.
Lapp Epic 10.1710
The Lapp Epic 10.1710 is a 6-contact screw-terminated industrial connector receptacle with copper contacts and a pin-style arrangement. You'd choose it when you need to terminate a control cable into a six-pin receptacle. The trade-off is scope: it's a connector, not a communications module, so it won't provide Ethernet or remote I/O. If your project is about making a physical connection, the Lapp Epic offers a screw-terminated design that fits the job. The copper contacts provide a solid signal path. The six-contact layout gives you multiple wiring points in one receptacle.
Final choice by use case
For remote I/O expansion, the H2-ERM100 at $159 is the part to add. For a control wiring connection, the Lapp Epic 10.1710 at $50 is the fitting choice. If you're expanding a DL205 rack, start with the module. If you're building a cable assembly or panel wiring, start with the receptacle. Their price difference is $109, so let the task determine the buy.
