When you're choosing a remote I/O module in the control cables connectors io space, the decision usually comes down to the controller family you already have and the type of signal you need to bring in. Do you need a network link between a DirectLOGIC DL205 system and its remote I/O? Or do you need an input module that accepts current-transformer signals for a Novar Opus setup? This comparison puts the Automation Direct H2-ERM100 / H2ERM100 DirectLOGIC DL205 remote I/O module against the Honeywell NOVAR Opus XIO-8CTI-B Remote I/O Module with CT 22-28VAC 50/60Hz NEW.
Quick verdict
If your control system is built around a DirectLOGIC DL205 CPU, the H2-ERM100 is the lower-priced option and the one for network-oriented remote I/O. If your application calls for the specialized Opus input module, the XIO-8CTI-B is the one to pick. Match the module to your controller family first; the price difference settles it when both are viable.
At a glance
| Module | Listed price | Connection / input | Best matched for |
|---|---|---|---|
| Automation Direct H2-ERM100 / H2ERM100 DirectLOGIC DL205 remote I/O module | $159.00 | 1 Ethernet 10/100Base-T port | DirectLOGIC DL205 systems using D2-240, D2-250, D2-250-1, D2-260, D2-262, or Do-more H2 series CPUs |
| Honeywell NOVAR Opus XIO-8CTI-B Remote I/O Module with CT 22-28VAC 50/60Hz NEW | $284.88 | Current transformer input module for 22-28VAC 50/60Hz | CT-based monitoring with a Novar Opus control network |
Where each module wins
The H2-ERM100 wins when your system uses a DirectLOGIC DL205 CPU and you want the lower-priced option. Its compatibility list covers D2-240, D2-250, D2-250-1, D2-260, D2-262, and Do-more H2 series CPUs, so it fits a range of common DL205 controllers.
The XIO-8CTI-B wins when the Opus platform is your architecture and you need the specialized input module. It is the higher-priced unit, but it brings a different input path to a Novar Opus system.
Product notes
Automation Direct H2-ERM100 / H2ERM100 DirectLOGIC DL205 remote I/O module
The H2-ERM100 is built for DirectLOGIC DL205 users who want to connect remote I/O over a network link. It is priced at $159.00 and includes one 10/100Base-T Ethernet port for that connection. Supported CPUs include D2-240, D2-250, D2-250-1, D2-260, D2-262, and Do-more H2 series CPUs. The condition is new - open box, so the unit is unused but the original box has been opened. The key limitation is compatibility: it is not compatible with the D2-230 CPU or with H2-WPLCx-xx expansion. If your DL205 system uses either of those, you need a different remote I/O module.
Honeywell NOVAR Opus XIO-8CTI-B Remote I/O Module with CT 22-28VAC 50/60Hz NEW
The XIO-8CTI-B covers the current-transformer input side of this comparison. It is an input module with a current transformer, built for 22-28VAC 50/60Hz operation. That makes it a good fit for a Novar Opus system where you need to bring CT signals into the controller. The condition is new. The limitation is the same specialization: before you choose it, confirm that your panel supplies 22-28VAC 50/60Hz, because that is the stated operating range for this module. If your control voltage is different, this particular module may not match your system.
Final choice by use case
For a DirectLOGIC DL205 system that needs a network-based remote I/O link, choose the Automation Direct H2-ERM100. For a Novar Opus system that needs the specialized input module, choose the Honeywell NOVAR Opus XIO-8CTI-B. The H2-ERM100 is the network-oriented pick for DL205 installations; the XIO-8CTI-B is the input specialist for Opus applications.
