Allen-Bradley 1746-BAS-5/02 | SLC 500 BASIC Programming Module

Flexible Programming and Control

The Allen-Bradley 1746-BAS-5/02 provides BASIC-52 language support for advanced data handling and custom device control. Engineers use this module when standard ladder logic cannot manage complex communication or data manipulation tasks.

Memory and Storage Features

This module includes 8 KB of battery-backed RAM for user programs and data. In addition, it offers 32 KB of Flash EEPROM for reliable program storage and easy firmware updates. A replaceable 1747-BA lithium battery ensures data retention during power loss.

Serial Communication Capabilities

The Allen-Bradley 1746-BAS-5/02 integrates two serial ports, one RS-232 and one RS-422/423. It supports ASCII and binary data exchange, allowing flexible connections to barcode readers, modems, and printers. Moreover, baud rates range from 110 to 19,200 bps for broad device compatibility.

Technical Performance

Operating within a temperature range of 0°C to 60°C (32°F to 140°F), the module is designed for demanding industrial environments. It requires 550 mA at 5V DC from the backplane, while the 24V DC supply remains unused. This ensures efficient power consumption inside the SLC 500 chassis.

Typical Applications

Users often deploy the Allen-Bradley 1746-BAS-5/02 for barcode integration, serial device interfacing, and printer communication. Its ability to run independently of the PLC scan cycle allows seamless multitasking without affecting system performance.
