ALLEN-BRADLEY 1769-ASCII CompactLogix Communications Module | 2-Channel RS-232/RS-422/RS-485

Description

• The 1769‑ASCII Compact I/O Communications Module from Allen-Bradley (Rockwell Automation) is a versatile ASCII communications interface module designed for CompactLogix and compatible PLC systems. Featuring two independent channels, it supports a mix of RS-232, RS-422, and RS-485 serial protocols for connecting a wide range of ASCII-based devices.

  This rugged module enables bi-directional communication with barcode scanners, weigh scales, HMIs, printers, and other field devices that use ASCII messaging protocols. Each port can be configured independently, with two full-duplex RS-232/RS-422 ports and two half-duplex RS-485 ports for flexible serial networking.Radwell International

  Ideal for industrial automation and discrete manufacturing systems, the 1769-ASCII seamlessly integrates into your CompactLogix architecture to expand communication capabilities without additional gateways.
