triconex  3721（3721C）3721N Differential Analog Input Module

Part number: 3721N,3721,3721C

Manufacturer:TRICONEX

Product Description:Differential Analog Input Module

Triconex 3721 is a differential analog input module used in programmable logic controllers (PLCs) to measure analog signals from various devices. It has a resolution of 16 bits and can measure signals in the range of -10V to +10V or 0V to +10V. The module has 8 channels, with each channel having a sampling rate of 8ms.

Here are the steps to use Triconex 3721 in a PLC program:

Connect the module to the PLC rack and power supply.Configure the module in the PLC programming software. This includes setting the module address and the configuration for each channel, such as the signal range and filter settings.

Write the PLC program to read the analog signals from the module. This involves using the appropriate instructions or function blocks to read the module data and convert it to engineering units.

Test the program and verify that the analog readings are accurate. This can be done by connecting a known signal source to the module input and comparing the PLC reading to the expected value.
