Technical Specifications & Selection Guide

Selection Guide: The 1764-28BXB1 is the relay-output variant of the MicroLogix 1500 28-point base. If your application requires transistor (DC) outputs for high-speed switching or PWM control, consider the 1764-28BXB series alternatives. For applications requiring more than 28 I/O points, this base unit supports up to 6 expansion modules via the local I/O bus.

Typical Application Scenarios

Oil & Gas Processing: Wellhead control panels and pipeline monitoring stations demand heavy-duty relay outputs capable of switching motor starters and solenoid valves under harsh environmental conditions. The 1764-28BXB1’s Class I Div 2 rating and robust relay outputs make it a proven fit for upstream and midstream automation.

Power Plants & Utilities: Auxiliary control systems for cooling towers, pump stations, and switchgear automation require deterministic scan times and reliable network communication. The DH-485 port enables integration into plant-wide SCADA architectures without additional gateways.

Food & Beverage Manufacturing: Batch processing lines, conveyor sequencing, and CIP (Clean-in-Place) systems benefit from the MicroLogix 1500’s compact footprint and hot-swap I/O capability, reducing changeover downtime in high-throughput facilities.

Automotive Assembly: Fixture control, end-of-line testing stations, and material handling systems leverage the 1764-28BXB1’s precision logic execution and RSLogix 500 compatibility for rapid program deployment across multiple production cells.

Water & Wastewater Treatment: Pump sequencing, level control, and chemical dosing applications in municipal treatment plants rely on the module’s wide temperature tolerance and proven reliability in continuous-duty cycles.
