Voltage Attenuator and Current Transformer

DNM-800 series is a Voltage Attenuator and Current Transformer designed for used in high-voltage applications. The current can be converted into +/-10 Vpp attenuated signal, so that a general electronic measuring device is able to read the signals. Compared to ICP DAS power meter products (PM-3033, PM-3133, PM-4324, etc.), in addition to AC signals, the DNM-800 series can convert DC signals as well.
The users can use appropriate ICP DAS Remote I/O Modules such as: M-7017R, I-87017RW, or ET-7217 to measure the converted +/-10 VDC signal via DNM-800 series. And use M-7017RMS or I-87017W-RMS, etc. to measure the AC signals.
By using DNM-800 series, the power data of all kinds of machines and AC/DC motors can be easily measured and retrieved, and then the analyzed data can be used to develop a model to build a failure warning system.

Applications

The operating current of AC or DC motor of the machines is converted into +/-10 Vpp attenuated signal via DN-844, and then the +/-10 Vpp signal is converted based on Modbus/RTU protocol for seamless integration with all kinds of PLC or SCADA.
