Description

The A-B 1746-FIO4I is A PLC (Programmable logic controller) module manufactured by Allen-Bradley (now a brand of Rockwell Automation) as part of the SLC 500 product family. The following is A detailed analysis of the A-B 1746-FIO4I module:

1. Basic information
Brand: Allen-Bradley (Rockwell Automation)
Model: 1746-FIO4I
Series: SLC 500
Second, functional characteristics
Analog input and output:
The A-B 1746-FIO4I module features two 12-bit resolution analog input channels that can be configured for 0-20 mA current or 0-10VDC voltage input signals.
At the same time, the module also contains two 0-20 mA analog output signals with a resolution of 14 bits.
Compatibility:
The module is compatible with modular and stationary SLC-500 hardware and can be seamlessly integrated with other SLC 500 series modules.
When used with specific stationary controllers, such as the 1747-L20, 1747-L30, and 1747-L40, it supports connection to other modules on the extended I/O rack.
High precision:
The overall accuracy of the analog input channel is ±0.440% of full scale at 25 degrees Celsius and ±0.750% of full scale at 60 degrees Celsius.
The overall accuracy of the analog output is ±0.298% of full scale at 25 degrees Celsius and ±0.541% of full scale at 60 degrees Celsius.
Quick response:
The module has a nominal conversion time of 7.5 μs per 512 μs and a step response of 100 μs, making it suitable for applications that require a fast response.
Versatility:
Due to its combination of analog input and output modules, the A-B 1746-FIO4I is particularly suitable for applications where expansion space is limited.
3. Technical specifications
