800 Series I/O Modules

The 800 Series I/O Modules are a family of programmable logic controller (PLC) input and output cards manufactured by Modicon. These boards handle field-level signal interfacing between a PLC system and connected industrial equipment, covering both discrete and analog functions.

Product Range

The series spans a broad set of I/O module types identified by Modicon B-prefix part numbers (for example, B802 through B883), including:

• Discrete input boards for 115VAC, 120VAC, and 24VDC signals
• Discrete output boards and modules for 115VAC, 120VAC, 24VDC, and 5VDC loads
• Relay output and output register boards
• Analog input and temperature control input boards
• Specialty modules such as a high-speed counter and a 24V input latch

With input modules, output modules, and dedicated function cards all sharing the 800 Series platform, this family provides the field I/O for Modicon PLC-based control systems.
