Information
- Modicon AS-J890-101. When servicing AS-J890-101 on an installed RIO drop, preserve the drop address, coaxial route and rack power budget.
I/O at drop: 800 Series I/O
RIO head: S908 or Quantum CRP93X
RIO cable ports: One coaxial F-connector port
The S908 network links a head processor to remote I/O drops. The installed cable topology, termination and drop addressing belong to the project design.
Before replacement, calculate the 800 Series rack’s module current against its selected supply, retain the drop identity and confirm RIO communications after commissioning.

Modicon AS-J890-101 installation guide
Prepared by Apter Power - PDF, 5 pages. Installed-system review, configuration checks, commissioning and handover.
Application scope: Use it for RIO drop service where the host, rack capacity and drop addressing match the complete -101 execution.
-
800 Series I/O drop
The AS-J890-101 links an 800 Series I/O rack to a documented S908 remote I/O network. -
RIO head compatibility
The documented architecture uses an S908 or Quantum CRP93X RIO head. -
Single coaxial port
The -101 execution provides one coaxial F-connector RIO cable port. -
Device-port boundary
The -101 execution has no ASCII device ports; other J890/J892 variants have different port arrangements.
Compare the sum of rack-module current with the installed power-supply capability.
Isolate and label the coaxial connection before removing the adapter.
Restore the drop address and check host-to-drop I/O communications under the site test procedure.
Do not interchange the one-port -101 adapter with a two-port -102 arrangement without redesigning the cable path.
Record the drop address and installed cable termination before removal.
Verify each fitted I/O module response through the RIO head after reinstallation.
Alternative Names
Technical notes
Installation relationship: The adapter sits at an 800 Series I/O remote drop between the S908 cable and the rack backplane.
Configuration boundary: Keep the -101 one-port identity and verify rack power, drop address and network topology against the installed system.

FAQ View All FAQ
-
What role does AS-J890-101 serve?It is a remote I/O drop adapter for an 800 Series I/O installation on the S908 RIO architecture.
-
How many RIO cable ports does AS-J890-101 provide?The J890-101 reference has one RIO cable port. The J890-102 is a different two-port execution.
-
Does AS-J890-101 have ASCII device ports?No. The J890-101 has zero ASCII ports; J892 variants are separate references with ASCII support.
-
Which I/O family is connected by AS-J890-101?The documented drop uses Modicon 800 Series I/O modules.
-
Which head processors are documented for AS-J890-101?Schneider’s RIO adapter table lists S908 or Quantum CRP93X head arrangements.
-
Which RIO topology is identified for AS-J890-101?The one-port J890-101 is documented for linear or dual RIO cable topologies, subject to the installed network design.
-
Does AS-J890-101 replace an 800 Series rack power supply?No. Calculate the installed I/O module current and compare it with the selected power supply capacity.
-
Can AS-J890-101 be treated as the two-port J890-102?No. Preserve the -101 suffix because the RIO port count differs from the -102 execution.
