4. Product Introduction (Anti-Template)
The AS-P892-000 is a remote I/O processor module from the classic Modicon 984 / 800 Series architecture. It serves as the interface between a Modicon PLC and remote I/O drops using a single-cable RIO network, while also providing ASCII communication ports.
Installed in a remote drop, the module handles communication with the central processor, manages local I/O scanning, and supports ASCII devices. It operates on 120 V or 220 V AC and supplies power to the local I/O modules within its current ratings. Although Schneider Electric has long discontinued the P890/P892 family, these modules remain in service in many legacy installations and are still supported through surplus and repair channels. Later replacements (such as the ASP890300) were designed for backward compatibility with appropriate rewiring.

5. QC, Procurement & Logistics SOP
- Inbound Verification – Confirm full catalog number (AS-P892-000), revision labels, connector condition, and power terminal integrity. Photograph all identifiers.
- Live Rig Testing – Install in a compatible 800 Series rack or test setup, apply AC power, and verify module power-up, RIO communication, and basic ASCII port activity where possible.
- QA & Packaging – After functional inspection, protect connectors and terminals, clean the module, and pack in protective packaging with desiccant.
- Global Logistics & Export Compliance – Classify under the correct HS code for industrial PLC interface modules. Packaging must protect against mechanical shock; export documentation is prepared to minimize customs delays.
6. Technical Pitfalls & Integration Warnings
RIO Cable and Termination – Single-cable RIO networks require correct coax cable, taps, and termination. Improper cabling causes communication failures across the drop.
Power Wiring – The module accepts 120 V or 220 V AC. Incorrect voltage selection or wiring can damage the unit.
Current Budget – Local I/O modules draw power from the P892. Exceeding the 0.25/0.5 A ratings will cause undervoltage or module faults.
Replacement Compatibility – Newer modules (e.g., ASP890300) are functionally similar but may require connector rewiring and different power connections.
7. Frequently Asked Questions (FAQ)
What is the realistic global lead time for a verified AS-P892-000?
As a discontinued Modicon module, availability depends on surplus stock. Typical lead time after verification is 3–12 business days plus standard shipping.
What is the main function of the AS–000?
It is a single-cable Remote I/O (RIO) interface processor with ASCII ports for Modicon 800 Series I/O systems.
What voltage does it require?
120 V or 220 V AC, 50/60 Hz.
Is it still in production?
No. It has been discontinued by Schneider Electric. It is now a legacy/spare part.
What system is it used with?
Modicon 984 PLCs and 800 Series remote I/O drops.
Does it support dual-cable RIO?
No. The AS–000 is the single-cable version. Dual-cable versions existed in the broader P89x family.
What should be confirmed before ordering a replacement?
Exact catalog number, power voltage requirements, and compatibility with the existing RIO network and 800 Series I/O modules.
