Description:
The Allen‑Bradley 1734‑APB is a PROFIBUS‑DP network adapter for POINT I/O systems from Rockwell Automation, serving as the left‑most starter module to connect POINT I/O modules to PROFIBUS‑DP networks, acting as a PROFIBUS slave (communicating with a PROFIBUS master) and a POINTBus master (controlling up to 63 Series C+ I/O modules), ideal for distributed industrial automation needing integration with PROFIBUS‑DP infrastructure.
Product Overview:
This open‑style, DIN‑rail mounted (IP20) adapter operates on 10–28.8V DC (nominal 24V DC), powers I/O modules via POINTBus (1A max @ 5V DC), and features 4 dual‑color status LEDs (PROFIBUS, module, POINTBus, power) for rapid diagnostics. It offers reverse polarity protection, RIUP (Removal and Insertion Under Power) for hot‑swapping, and integrates with PROFIBUS‑DP masters for real‑time I/O control in manufacturing and process automation.
Key Features:
- Connects POINT I/O to PROFIBUS‑DP, acting as a PROFIBUS slave and POINTBus master for seamless data exchange
- Powers up to 63 Series C+ POINT I/O modules via POINTBus (1A @ 5V DC), scalable with 1734‑EP24DC power supplies
- 4 dual‑color LEDs for instant troubleshooting of PROFIBUS link, module health, POINTBus communication, and power states
- RIUP support allows hot‑swapping I/O modules without system shutdown, minimizing maintenance downtime
- Reverse polarity and overvoltage protection enhance durability in harsh industrial environments
- Input dropout protection maintains POINTBus output within specs for 10ms at 10V with max load, ensuring operational continuity
