Information About 1734-232ASC
The 1734-232ASC is an ASCII communication module within the Allen-Bradley POINT I/O family, providing a streamlined method for bringing standalone ASCII devices into distributed I/O architectures. Designed for modular expansion, it mounts directly on POINT I/O terminal bases and draws minimal power from both the external supply and the POINTBus backplane. Its full-duplex RS-232 interface supports a wide variety of serial framing formats—including 7-bit and 8-bit configurations—and baud rates from 1200 to 38.4 kbps.
The module offers extensive configuration options for ASCII messaging, including selectable start and end delimiters, record handling modes, and up to 128-character input buffering. These features enable efficient communication with devices such as barcode scanners used for product identification, sorting, and inspection processes. Diagnostic visibility is enhanced through front-facing LED indicators that display module status, network state, and transmit/receive activity.
Compact in size and adaptable for both horizontal and vertical installation, the 1734-232ASC supports key POINT I/O features such as removal and insertion under power (RIUP), auto-device replacement (ADR), and flexible module positioning via keying. Its open-style design supports a variety of industrial applications where serial device integration, low power consumption, and modularity are essential.
Key Features
- Full-Duplex RS-232 Port: Supports one complete serial channel for ASCII device communication.
- Flexible Serial Configuration: Compatible with multiple character framing formats (7N2 through 8O1) and baud rates up to 38.4 kbps.
- Wide Input Voltage Range: Accepts 10–28.8 VDC external power with 24 VDC nominal operation.
- Compact POINT I/O Design: Easily mounts to 1734-series terminal bases for modular expansion.
- Advanced Message Handling: Supports configurable start/end delimiters and up to 128-character receive buffering.
- Integrated Diagnostics: Includes module, network, TXD, and RXD LED indicators for quick troubleshooting.
- Low Power Consumption: Draws only 75 mA from POINTBus and 15 mA from the external supply.
- Industrial Temperature Rating: Operates from –20°C to 55°C for demanding environments.
The 1734-232ASC delivers the reliability and precision required for serial ASCII communication in distributed POINT I/O control systems.
