Description
Product Overview
The Allen-Bradley 1734-ACNR is a POINT I/O ControlNet adapter module designed by Rockwell Automation to interface I/O modules directly to high-speed ControlNet networks. It provides high-speed data transfer between controllers and field devices while supporting redundant media connections to maintain network reliability in critical automation systems. Powered by a standard 24V DC input supply (10.2 to 28.8V DC range), the 1734-ACNR supplies up to 1000 mA (1 Amp at 5V DC) of POINTBus backplane current to drive connected expansion modules. Featuring a compact form factor with an approximate net weight of 0.10 kg (0.22 lbs), it supports up to 5 rack-optimized connections for digital modules and up to 25 direct connections for analog/specialty modules, expandable up to 63 modules per node using 1734-EP24DC expansion power supplies (compatible with Series C or later modules).

Key Hardware & Operational Features
- Redundant ControlNet Media Ports: Dual coax media connectors allow redundant cabling configurations to prevent communication downtime on industrial networks.
- High-Density Expansion Capacity: Supports 5 rack-optimized connections and 25 direct analog connections, expandable up to 63 I/O modules per node with 1734-EP24DC power supplies.
- Network Access Port (NAP): Includes a dedicated local communication port for convenient field diagnostics and configuration tools without interrupting main control traffic.
- Integrated Reverse Polarity Protection: Built-in electrical protection safeguards internal electronics against reverse wiring errors during field setup.
Installation & Field Wiring Guidelines
1. DIN Rail Mounting: Snap the adapter module onto a standard 35 mm DIN rail prior to installing adjacent POINT I/O terminal bases.
2. Power Wiring: Connect a clean 24V DC class 2 power supply to the removable field-power terminals, adhering to polarity markings.
3. Media Connection: Attach ControlNet coaxial cables to channel A and channel B BNC ports. Ensure proper network termination resistors are installed at network endpoints.
