Overview
The Modicon AS-B805-016 is a 115VAC 16-point input module designed for the Modicon Automation 800 I/O system. This module interfaces between field devices (push buttons, limit switches, proximity sensors, and other 115VAC sources) and the PLC, converting AC input signals into digital logic levels that the controller can process. The AS-B805-016 is commonly found in legacy Modicon/Gould automation systems and remains in active use across manufacturing, process control, and machine automation applications.
Key Features
- 16 input points organized in two groups of 8 channels
- 115VAC input voltage compatibility
- Senses and converts switched input signals to PLC logic levels
- Compact module form factor for B805 backplane mounting
- Reliable performance in industrial environments
- Drop-in replacement for equivalent Modicon B805 input modules
