Allen-Bradley 1766-L32BXBA | MicroLogix 1400 PLC Controller

Product Overview

The 1766-L32BXBA is an Allen-Bradley MicroLogix 1400 controller designed for compact industrial automation. It delivers 32 built-in I/O channels suitable for small to medium applications while supporting up to seven additional 1762 I/O expansion modules.

Input and Output Channels

This PLC includes Twelve (12) fast 24VDC inputs for high-speed signals and Eight (8) standard 24VDC inputs for typical digital devices. It also provides Two (2) analog voltage inputs supporting 0–10 VDC.

The outputs include Six (6) relay contacts, Three (3) fast DC, Three (3) standard DC, and Two (2) voltage output channels rated 0–10 VDC. Relay outputs operate within 5–125 VDC or 5–264 VAC ranges.

Communication and Networking

The 1766-L32BXBA features one isolated RS232/485 combo port, one non-isolated RS232 port, and one Ethernet port. Supported protocols include DF1, ASCII, MODBUS RTU, DNP3, DH485, Ethernet/IP, MODBUS TCP/IP, and DNP3 Ethernet.

Power and Performance

Operating on 24VDC, this controller has a power consumption of 15 A for 20 ms during inrush and operates at 47–63 Hz. Built-in RTC functionality allows precise timestamping for critical processes.

Memory and Expandability

The 1766-L32BXBA includes 20 KB of memory for storing user programs. Users can expand its capabilities by connecting up to seven 1762 I/O modules, offering increased channel capacity and versatility.
