When you're choosing parts for a control panel, the comparison between a cable assembly and a remote I/O module can feel awkward, but both live in the same control cables, connectors, and I/O world and both can determine whether a line runs today. The real question is what your existing system needs: a direct replacement cable for equipment already using Klockner Bartelt control wiring, or a network-ready module that extends a DirectLOGIC DL205 rack. This head-to-head lays out the difference.
Quick verdict
If your machine already uses Klockner Bartelt control cabling, the Klockner Bartelt 500081 6 is the part to pick. If you're building or expanding a DirectLOGIC DL205 system and need Ethernet remote I/O, the AUTOMATION DIRECT H2-ERM100 / H2ERM100 DirectLOGIC DL205 remote I/O module is the one to get. The listed prices are nearly identical-$159.99 for the cable assembly and $159.00 for the module-so your decision should rest on compatibility and condition, not on the small spread.
| Product | Listed Price | Price Bar | Condition | What It Is |
|---|---|---|---|---|
| Klockner Bartelt 500081 6 Industrial Control Cable Assembly | $159.99 | Used | Cable assembly for industrial control equipment | |
| AUTOMATION DIRECT H2-ERM100 / H2ERM100 DirectLOGIC DL205 remote I/O module | $159.00 | New - Open box | 1-port Ethernet remote I/O module for DL205 |
Where each product wins
Klockner Bartelt 500081 6 wins when you need a like-for-like replacement for an existing Klockner Bartelt cable in a pneumatic, hydraulic, electronic, or electrical control setup. It is a used assembly, so it's aimed at maintenance and repair work where matching the original wiring style matters more than having a brand-new part.
AUTOMATION DIRECT H2-ERM100 wins when you're adding remote I/O capacity to a DirectLOGIC DL205 system. It's a new open-box module with an Ethernet 10/100Base-T port, and it gives you a modern connectivity path without leaving the DL205 family.
Product notes
Klockner Bartelt 500081 6 Industrial Control Cable Assembly
If your panel already speaks Klockner Bartelt, this cable assembly is the straightforward replacement path. It is a used industrial control cable assembly rather than a new part, so plan to inspect it before you rely on it. The MPN 500081-6 helps you identify the exact assembly you're ordering, and it's intended for pneumatic, hydraulic, electronic, and electrical control equipment, making it a versatile spare to keep on the shelf. The limitation is the used condition: because multiple quantities may be available, the exact unit pictured may not be the one you receive. That makes it a better fit for non-critical repairs or for shops that keep spares on hand, rather than for a production line where every unit must match a specific revision.
AUTOMATION DIRECT H2-ERM100 / H2ERM100 DirectLOGIC DL205 remote I/O module
For a DirectLOGIC DL205 control system, the H2-ERM100 is the easier path to Ethernet remote I/O. It has one 10/100Base-T port and works with the D2-240, D2-250, D2-250-1, D2-260, D2-262, and Do-more H2 series CPUs, so it fits a broad set of existing racks. It is new open box, so you get a fresh module without the used-part caveat. The limitation is compatibility: it is not supported on the D2-230 CPU or H2-WPLCx-xx modules, so you need to make sure your processor is on the supported list before ordering. If it is, this module gives you a straightforward way to add remote I/O to a proven PLC lineup.
Final choice by use case
Pick the Klockner Bartelt 500081 6 if you're repairing or restocking a panel that already uses Klockner Bartelt control cables, especially when you want the same style of assembly the machine was built with. Pick the AUTOMATION DIRECT H2-ERM100 if you're adding remote I/O to a DirectLOGIC DL205 system with a compatible CPU and want Ethernet connectivity. If your project is a new build, the module is the more future-proof purchase because it expands your I/O footprint; if you're keeping an existing line running, the cable assembly is the part that gets it back online.
