Technical Specifications & Selection Guide

Selection Considerations
When specifying the 1766-L32AWA for your application, evaluate: maximum I/O count requirements, analog signal types (voltage/current/thermocouple), communication protocol needs (Ethernet/IP vs. Modbus), environmental conditions (temperature/humidity/vibration), and power supply availability (24V DC source capacity). For applications exceeding 32 I/O points, consider expansion modules or higher-capacity MicroLogix 1400 models (1766-L32BWA, 1766-L32BWAA).
