Phoenix Contact 2878447

The Inline Analog Input Terminal, designated as IB IL AI 4/EF-PAC, is engineered for industrial applications, featuring four analog inputs capable of handling various signal ranges such as 0 V to 5 V, -5 V to 5 V, and current inputs from 0 mA to 20 mA. This module supports connection technologies including 2-, 3-, and 4-conductor configurations, offering flexibility in wiring.

Operating with a transmission speed of 500 kbps, it is designed for integration into local bus systems. The device adheres to the IP20 protection degree, ensuring suitability for standard industrial environments. With a weight of 210 g, it maintains compact dimensions of 48.8 mm in width, 135 mm in height, and 71.5 mm in depth.

For efficient data processing, this terminal is equipped with a 16-bit A/D converter, delivering a maximum conversion time of 10 µs. The input resistance for voltage signals is approximately 300 kΩ, while the current input resistance is typically 110 Ω. Diagnostics capabilities include internal I/O supply failure notifications sent to the bus coupler, enhancing operational reliability.

Specifications such as an operational temperature range from -25 °C to 55 °C, and humidity tolerance between 10% to 95% (non-condensing) further optimize its functionality in diverse environments. The Inline connectors and marking fields included in the package support streamlined installation and identification.
