The 1734-VTM is an analog input module from the Allen-Bradley 1734 series of Compact I/O modules manufactured by Rockwell Automation for their programmable logic controllers (PLCs). The module is specifically designed to provide voltage and current measurement capabilities to a PLC system.

The 1734-VTM module offers multiple channels, typically ranging from 2 to 8, depending on the specific model. Each channel is used to measure analog signals such as voltage or current from external devices or sensors.

The module supports various signal types, including DC voltage, AC voltage, DC current, and AC current. It typically provides a configurable input range to accommodate different signal levels. The configuration can be done through the PLC programming software, where you can specify the desired input range for each channel.

Once the signals are captured by the 1734-VTM module, they can be processed and used by the PLC program for control and monitoring purposes. The PLC program can perform calculations, comparisons, or trigger specific actions based on the analog input values received from the module.
