EtherNet/IP and I/O Density Scaling Characteristics
The Allen-Bradley 1764-28BXB1 base unit is part of the MicroLogix 1500 PLC platform and provides integrated discrete signal handling through a mixed I/O configuration. The unit supports 16 digital inputs and 12 output points consisting of six relay channels and six FET transistor channels.
The MicroLogix 1500 architecture supports EtherNet/IP and serial communication interfaces for PLC network integration. I/O density scaling is managed through the controller platform and expansion configuration, allowing discrete machine control signals to be processed through the base unit hardware.
The module design supports firmware flash compatibility within the MicroLogix 1500 product family, allowing controller software revisions to maintain communication and I/O execution compatibility.

Field Installation Guidelines
Install the 1764-28BXB1 on a control panel or DIN rail mounting structure according to the MicroLogix 1500 installation requirements. Verify that the 24 VDC power wiring polarity matches the terminal designation before energizing the module.
Separate communication cables and low-level signal wiring from high-voltage power conductors and switching devices. Apply shielded cable practices where electromagnetic interference may affect signal integrity, with cable shields connected according to the control cabinet grounding standard.
Confirm input and output terminal assignments before field wiring. Check relay and transistor output load compatibility with connected devices before commissioning the control system.
