Description
The Schneider Electric Modicon AS-J890-002 is a dual-channel remote I/O (RIO) processor interface module designed for Modicon 800 Series I/O systems and legacy 984 programmable logic controllers. It serves as a high-speed communication link between the local controller chassis and remote I/O drops over an S908 coaxial network. Featuring dual coaxial ports and diagnostic LEDs, the module enables deterministic real-time data exchange while providing media redundancy to maintain system availability.
System Communication and Network Architecture
The AS-J890-002 operates as a remote I/O head node on the proprietary S908 protocol, executing high-speed deterministic transfers at 1.544 Mbps over coaxial cable networks. Its dual-channel design features twin F-connector ports, allowing dual-cable or redundant-path cabling topologies to safeguard communication against single line breaks.
The module manages input and output data transfers across remote drops with typical update cycles under 1 ms per drop. Integrated rotary or DIP switches allow engineers to set specific drop address configurations directly on the hardware.
Operational Diagnostics and System Integration
Front-panel status LEDs provide immediate feedback on module health, communication activity, and line error detection. These visual status indicators allow field maintenance staff to verify network health and isolate link errors without external monitoring tools.
Occupying a standard slot position in the Modicon 800 Series primary backplane/housing, the unit draws its operating power directly from the internal system power supply across the backplane bus.

Frequently Asked Questions
Q: What is the main operational difference between the AS-J890-001 and the AS-J890-002 modules?
A: The AS-J890-001 is a single-channel S908 remote I/O processor module, whereas the AS-J890-002 features a dual-channel design with dual coaxial ports to support redundant network cable topologies.
Q: How is the remote drop network address configured on the AS-J890-002?
A: The drop address is selected using the onboard DIP/rotary switches located on the module before inserting it into the 800 Series housing slot.
