High-Speed Remote I/O Communication
This processor module connects the main Quantum controller to remote I/O racks located up to several kilometers away. It uses the proven Remote I/O protocol at 1.544 Mbit/s for fast, deterministic data transfer. Therefore, the Schneider ASJ890002 enables centralized control of geographically distributed field I/O.
Support for Extensive I/O Networks
The ASJ890002 can address and manage data exchange with up to 32 individual remote I/O drops. Each drop can contain a mixture of analog and discrete I/O modules for maximum flexibility. As a result, you can build large-scale automation systems while keeping wiring and cabling costs low.
Flexible Physical Layer Options
You can configure this module to communicate over either standard coaxial cable or fiber optic media. Coaxial connections suit shorter distances within a plant, while fiber optics provide immunity to electrical noise. Consequently, the Schneider ASJ890002 adapts to various plant environments and grounding conditions.
Seamless Integration with Quantum Systems
You install the ASJ890002 into any slot of a Modicon Quantum local rack, drawing power from the backplane. It appears automatically in the controller’s I/O map, simplifying configuration in software. Therefore, system engineers can set up remote I/O without complex programming.
Comprehensive Diagnostic Capabilities
Four front-panel LED indicators provide immediate visual feedback on module and network health. The Active LED shows normal operation, while Fault and Network LEDs pinpoint issues quickly. This on-board diagnostics reduces troubleshooting time for maintenance personnel.
Rugged Design for Industrial Control Rooms
Schneider engineered this module for long-term reliability in standard industrial control room environments. It operates within a temperature range of 0°C to +60°C and withstands typical vibration levels. Its robust construction ensures consistent performance for years of continuous operation.
