Product Description

The Allen-Bradley 1771-IV Module is a PLC I/O Module designed for industrial automation applications, providing reliable integration within Allen-Bradley 1771 chassis-based systems. This module features a fixed configuration of 16 digital input channels, enabling direct connection to sensors, switches, or other digital signals. It operates within a voltage range of 10-30V DC, ensuring compatibility with standard industrial power supplies. Designed for harsh environments, the 1771-IV functions optimally in temperature ranges of 0°C to 60°C (32°F to 140°F), making it suitable for manufacturing, process control, and heavy machinery industries. The module supports seamless communication via the 1771 backplane, allowing scalable expansion with other I/O modules. Key advantages include rugged construction, straightforward installation, and compatibility with legacy PLC-5 systems. However, it lacks modern features like network connectivity or diagnostic LEDs. The 1771-IV requires no battery or display, emphasizing reliability over advanced functionality.
