A-B 1756-CN2R
The A-B 1756-CN2R module is an analog input module for A CompactLogix 5370 controller manufactured by Rockwell Automation under the Allen-Bradley brand. It is mainly used to collect analog signals from industrial sites, such as temperature, pressure, flow, etc., and convert these analog signals into digital signals that can be recognized by PLC.
Product characteristics
High precision: Provide high precision analog input, can accurately collect the field signal.
Multi-channel: provides multiple analog input channels, which can simultaneously collect multiple analog signals.
Isolation design: Each channel is isolated independently, improving anti-interference ability.
Flexible configuration: Supports a variety of ranges and unit configurations to meet different application requirements.
Product parameters (typical values, specific parameters please refer to the product manual)
Number of channels: 2 channels
Input type: Single-end input
Range: configurable

Product description
The 1756-CN2R module is connected to the analog output of the field device through its input terminals, converts the analog signals into digital signals, and then transmits these digital signals to the PLC. By reading these digital signals, PLC can monitor and control the status of the field equipment.
Application scenario
Process control: Used in process control system to collect process variables such as temperature, pressure and flow rate.
Data acquisition: Used in the data acquisition system to collect various analog data.
Machine control: Used in the machine control system to collect the running state of the machine.
