5. 防雷击保护：内置防雷击保护功能，可有效避免雷击对系统的损害。

1756-IF16 is an analog input module from Rockwell, used to monitor analog signals such as temperature, pressure, flow rate, etc. Its characteristics include:

With an independent resolution of 320 μ V/Count (15 bits+sign polarity) @ ± 10.25V input range, 160 μ V/Count (16 bits) @ 0-10.25V Input range, 80 μ V/Count (16 bits) @ 0-5.125V input range and 0.32 μ A/Count (16 digits) @ 0-20.5mA.

The scanning time of this module varies, for example, the single end scanning time is 16-488ms; 8-244ms (differential connection) and 5-122ms (high-speed differential connection).

It has the ability to use Σ-Δ The built-in analog-to-digital converter circuit of the method. The converted data is stored in IEEE 32-bit floating-point data format in integer mode (left aligned, 2-second complement).

The calibration accuracy of this module is better than 0.05% of the voltage input range and 0.15% of the current input range.

Application scenario:

This module is widely used in industrial automation and process control fields that require analog signal processing and conversion, such as injection molding machines, printing machines, bookbinding machinery, modular machine tools, grinding machines, packaging production lines, electroplating assembly lines, etc. In these scenarios, it can provide stable and reliable analog signal processing, improving production efficiency and quality.

Protective effect:

Short circuit protection: When a short circuit occurs, it can automatically cut off the power or reduce the current to prevent equipment damage.

Overload protection: When the device is overloaded, the output power can be reduced or the power can be turned off to protect the device from overload damage.

Temperature protection: Built in temperature sensor, capable of real-time monitoring of device temperature. When the temperature exceeds the set value, it will automatically reduce the current or turn off the power to prevent equipment overheating and damage.

Fault diagnosis and positioning: Equipped with fault diagnosis and positioning functions, it can timely detect and locate faults, making it convenient for users to repair and maintain.

Lightning protection: Built in lightning protection function can effectively avoid damage to the system caused by lightning strikes.
