MicroLogix 1400 Programmable Controller Overview

The MicroLogix 1400 programmable controller integrates a variety of essential components for industrial automation, including:

• Power supply
• Input and output circuits
• Processor
• Isolated combination RS-232/RS-485 communication port
• Ethernet port
• Non-isolated RS-232 communication port

It supports up to 32 discrete I/O points (20 digital inputs and 12 discrete outputs) and 6 analog I/O points (4 analog inputs and 2 analog outputs). The models 1766-L32BWAA, 1766-L32AWAA, and 1766-L32BXBA specifically feature these 6 analog I/O points.
