    Tips: How to install the voltage sensor?

    There are 3 installation methods of voltage sensor:

    1. Pin-welding installation of the circuit board: Make lines on the circuit board, and weld the voltage sensor to the circuit board like a component. Its advantages are small size, light weight, space saving and easy installation.
    2. Screw fixation installation: The voltage sensor is screwed to the bottom of the chassis or a fixed position, and the external connection is through a variety of different terminals. The advantages are very firm and easy to disassemble.
    3. DIN rail installation: There is a standard 35mm wide dovetail groove on the bottom of the voltage sensor, which can be installed at DIN rail. Its advantages are convenient, versatile, and suitable for field work installation.

    Integration with PLC
    Some of our machines use 40V batteries. When the battery is low, a regular charger won't work, and we need to use a portable charger for jump-charging. I'm looking for a function that can be integrated into the PLC to display a message on the HMI when the battery is about to run out.

    Okay, so you want to use a voltage sensor to monitor the battery voltage. When the voltage drops to a certain threshold, the sensor sends a signal to the PLC indicating that the battery voltage is low and needs charging, right? Our AC/DC Voltage Sensor, SKU: ATO-VOS-ACDC500, should meet your requirements.
    Measurement range
    Can the measurement range of this AC/DC voltage sensor (75mV to 500V, RMS output 0-5V/0-10V/4-20mA/0-20mA) be set to: 0-300V, output signal: 0-5V, power supply: 12V DC?

    ATO Responded
    Yes, this AC/DC voltage sensor supports a measurement range of 0-300V, an output signal of 0-5V, and a 12V DC power supply. You can order directly from the website.
    Voltage Data
    I am interested in the ATO-VOS-ACDC500: Can this device measure sinusoidal signals up to 10 V RMS (frequency range 1 kHz to 3.5 kHz) and provide an analog output (0–10 V DC) proportional to the RMS voltage for the data acquisition system to read?

    Unfortunately, our voltage sensor can only measure voltages at fixed frequencies, which is not suitable for your application.
    Sine wave converting
    Hello, I am looking to convert a 3 phase 300VAC sine wave down to a 0 to 10VAC sine wave to connect to a DAQ that has an analog input range 0f   - 10 volts. I'm looking to make measurements of the actual sine wave for power quality measurements. I am not powering anything. I am only taking measurements. Help would be appreciated. Thanks.

    Our three-phase voltage sensor can measure sine waves. However, the current output signal is DC 0-5VDC or 0-10VDC, which are effective value detection, and can Not output AC signal 0-5VAC or 0-10VAC.
    Good voltage sensor
    Very easy to use and clear installation. The AC voltage sensor works perfectly and is very affordable. It’s very suitable to drive the motors for a robot. If it needs to be used for larger motors, I could choose one with a larger measuring range. The instructions for use are very detailed. I am going to buy a few more.
