Product Description

Rayon Automation Technology Co., Ltd. As a supplier, the Allen Bradley 1746-NIO4V product offers relatively weak load capacity and lacks electrical isolation between channels. During wiring, it is essential to avoid using both high-voltage and signal lines together. If you are looking for something, please contact us as soon as possible.

Parameters

Specification	Details

Application scenarios:

1. Read two 0-10V valve opening feedback signals (input), and output two 0-10V/±10V signals to control the valve actuator (output).
2. Allen Bradley 1746-NIO4V outputs 0-10V signals to the frequency converter to adjust the motor speed. Reading the actual motor speed feedback or load voltage is done through voltage input.
3. Combined with 0-5V/0-10V output pressure transmitters or temperature transmitters, perform PID closed-loop regulation.
4. Used to generate adjustable voltage excitation signals (output) and collect the voltage response of the sensor (input) in laboratory equipment.

Advantages and Features

The Allen Bradley 1746-NIO4V adopts a highly integrated Combo design, using a single slot, providing pure voltage-type channels with 2 input and 2 output. It supports direct board data access. Data can be mapped to the I/O image table without the need for complex block transfer instructions. The combination of 12-bit or 13-bit high resolution and precision with industrial-grade photoelectric isolation and filtering anti-interference technology enables efficient space and cost savings for compact control cabinets in the after-sales service.

Model Replacement:
For the requirement of a direct replacement without modifying the program and rack, 1746-NIO4V is a direct board data mapping, eliminating the cumbersome use of block transfer (BTW/BTR) instructions. If you simply want a cheaper and easily available direct replacement part, you can consider the compatible module from ProSoft Technology. If you take this opportunity to upgrade the entire old system, you can switch to the Siemens S7-1200 series, paired with extremely stable and well-structured SM1231 AI (4 input channels) and SM1232 AO (2 output channels) analog modules. It is important to note that for a 12-bit resolution (0 - 4095), if the substitute uses a 16-bit resolution (0 - 32767 or 0 - 65535), the program SCP must be modified synchronously.
