Overview
Modicon ASP890300 is a slot-mount Remote I/O receiver processor module designed for Modicon 800 Series PLC installations. This drop receiver combines I/O interface capability with integrated AC/DC power supply, eliminating the need for a separate auxiliary power source at the remote drop location. It enables distributed control architectures over single or dual coaxial cable networks.
Key Features
- Integrated 115/230 VAC or 24 VDC selectable power supply
- Fast I/O processing: sub-5ms scan time for 256 I/O points
- Minimal RIO communication latency: less than 1ms for 256 I/O points
- Two half-duplex ASCII communication ports for flexible connectivity
- Slot Mount form factor for backplane integration
- Supports both single and dual coaxial cable RIO networks
