Technical Specifications

The 1734-EXT3 measures 3 meters in length, offering extended reach compared to shorter variants. It belongs to the POINT I/O series and functions specifically as a POINTBus extension cable. The cable features open-style connectors on both ends for straightforward integration with terminal bases. Furthermore, it is compatible with the 1794 modular POINT I/O system. This cable supports various I/O types, including analog, digital, RTD, AC/DC, specialty, and thermocouple I/O. It also works seamlessly with multiple adapters such as DeviceNet, Ethernet/IP, ControlNet, and Profibus adapters. The 1734-EXT3 enables connectivity to networks like ControlNet, DeviceNet, Ethernet/IP, OPC/DDE, and PROFIBUS DP I/O.

Key Features and Benefits

The 1734-EXT3 offers significant advantages for system designers and maintenance personnel. Its 3-meter length provides flexibility in module placement within cabinets. For instance, you can position power supplies and communication modules at convenient locations without signal degradation. Additionally, this cable supports the RIUP feature, which allows users to remove and insert modules under power. This capability minimizes downtime during maintenance or system expansion. The cable also ensures high-speed data transmission between the main I/O system and connected devices. Meanwhile, its robust construction meets Allen‑Bradley's quality standards, guaranteeing long-term reliability in demanding industrial environments.

System Compatibility and Integration

The POINT I/O system, when used with the 1734-EXT3, supports up to 504 channels or 63 I/O modules per node. This scalability makes it suitable for both small and large automation projects. The system consists of four main components: I/O modules, communication modules, terminal base units, and power distribution modules. Users can install up to 8 points per I/O module. Specialty modules available include RS-485, RS-232, RTD, 1 MHz counter inputs, encoders, and Serial Synchronous Interface (SSI) modules. Therefore, the 1734-EXT3 serves as a critical link between these components, enabling seamless communication and integration.

Installation and Usage Guidelines

Installing the 1734-EXT3 is a straightforward process. Simply connect the open-style connectors to the appropriate terminal bases within your POINT I/O system. Ensure the cable is routed properly to avoid strain or damage. For optimal performance, keep the cable away from high-voltage power lines to minimize electromagnetic interference. Although the system supports RIUP functionality, always exercise caution when connecting or disconnecting the cable. Proper installation guarantees stable signal transmission and prevents data loss. This cable's 3-meter length offers ample flexibility for complex cabinet layouts.
