Overview
The Allen-Bradley 1734-ADN is a POINT I/O DeviceNet network adapter that bridges local POINT I/O modules to a primary DeviceNet network. Operating as both a subnet master and DeviceNet slave, this adapter resides simultaneously on the Subnet and the primary DeviceNet network, enabling seamless distributed I/O implementation in industrial automation systems.
Key Features
- Supports up to 63 powered POINT I/O modules (up to 504 I/O points)
- Multiple DeviceNet communication rates: 125 Kbps, 250 Kbps, 500 Kbps, and 1 Mbps with AutoBaud detection
- Configurable node address (0–63, or 64–99 via RSNetWorx software)
- Auto Device Replace (ADR) feature transfers configuration parameters to replacement modules automatically
- DIN rail mounting with screw terminal connections
- Three status LEDs and power indicators for easy troubleshooting
