SCHNEIDER 170 BDI 346 00 Digital Input Module

The Schneider Electric 170 BDI 346 00, also known as the 170BDI34600, is a digital input module within the Modicon Interbus S bus network of the classic Modicon automation platform. It's primarily used for reading digital signals from sensors or switches in industrial control systems.

Here's a breakdown of its specifications and features:

Specifications:
Function: Reads digital input signals from up to 16 sensors or switches.
Voltage compatibility: Operates on 24V DC positive logic, compatible with standard industrial sensors.
Input type: Accepts sinking inputs (current sink) for improved noise immunity.
Response time: Offers fast response times of typically 1.5 ms per channel, suitable for dynamic control applications.
Communication protocol: Connects to the Modicon Interbus S bus network for data exchange with the PLC.
Dimensions: Compact design with approximate dimensions of 125 x 141 x 45 mm.

Features:
LED indicators: Provides individual LEDs for each input channel to visualize signal status and simplify troubleshooting.
Short-circuit protection: Each input channel is protected against short circuits for reliable operation.
Hot-swappable: Can be replaced while the system is running without interrupting other modules, minimizing downtime.
DIN rail mountable: Easy to install on standard DIN rails for efficient space utilization in control cabinets.

Applications:
The 170 BDI 346 00 is commonly used in various industrial automation tasks, including:
Machine control: Monitoring machine states like limit switches, safety interlocks, and pushbuttons.
Process control: Reading sensor data (e.g., object presence, position, end-of-stroke) for process monitoring and control.
Building automation: Monitoring building systems like security sensors, door switches, and emergency buttons.
Remote monitoring and control: Enabling remote access to system status and control based on digital input signals.
Please note: The 170 BDI 346 00 is considered a discontinued product by Schneider Electric. While some suppliers might still offer new or refurbished units, it's important to consider future upgradeability and availability of spare parts when using this module in new designs.
