Product Details

The ADE12011 is a single channel, configurable, isolated digital input monitoring solution for energy transmission and distribution applications. The ADE1201 is configured through the serial port interface (SPI) to perform an isolated measurement of the digital input that is also called binary input or contact input. The ADE1201 digital output signal on the DOUT1 pin reflects the state of the input signal after user configurable signal conditioning. The SPI protocol supports addressing to allow up to eight devices sharing one 4-wire SPI port.

The ADE1201 application circuit accepts a wide range of input voltages from ±10 V dc to ±300 V dc, or 8 V rms to 240 V rms. The programmable wetting current and robust application circuit enable the device to meet stringent, system level electromagnetic capability (EMC) requirements.

The ADE1201 includes an isoPower® integrated, isolated dc-to-dc converter that eliminates the need for an external isolated power supply. The iCoupler® chip scale transformer technology is used to isolate the logic signals between the high voltage, isolated side and the low voltage, nonisolated side of the digital input monitor. This technology creates a small form factor design that includes data and power isolation.

An integrated successive approximation register (SAR) analog-to-digital converter (ADC) and a programmable gain amplifier (PGA) from 1× to 10× measure the analog inputs. The ADC waveforms are available through the SPI port to allow system level diagnostics.
