产品介绍
The Allen-Bradley 1771-IVN/C Low True Input Module is a digital input module designed for PLC-5 control systems, providing reliable signal acquisition from field devices operating with DC voltage levels. It is configured for low-true (sink) input logic, making it suitable for systems where input devices source current to the module.
This module supports 32 digital inputs organized into four groups / eight channels, enabling efficient monitoring / multiple field signals such as push buttons, limit switches, proximity sensors, and other discrete devices. Its group-based design simplifies wiring and enhances troubleshooting in complex industrial systems.
Built for integration within the 1771 I/O platform, the module ensures stable operation in harsh industrial environments, including areas with vibration and electrical noise. It is commonly used in automation systems requiring dependable and high-density digital input processing.
