GENERAL DESCRIPTION
The ADL5303 is a monolithic logarithmic detector optimized for the measurement of low frequency signal power in fiber optic systems and offers a large dynamic range in a versatile and easily used form. Wide measurement range and accuracy are achieved using proprietary design and precise laser trimming. The ADL5303 requires only a single positive supply, VPS, of 5 V. When using low supply voltages, the log slope can be altered to fit the available span. Low quiescent current and chip disable facilitate use in battery-operated applications. The input current, IPD, flows in the collector of an optimally scaled NPN transistor, connected in a feedback path around a low offset JFET amplifier. The current summing input node operates at a constant voltage, independent of current, with a default value of 0.5 V; this may be adjusted over a wide range. An adaptive biasing scheme is provided for reducing photodiode dark current at very low light input levels. The VPDB pin applies approximately 0.1 V reverse bias across the photodiode for IPD = 100 pA, rising linearly to 2.0 V of reverse bias at IPD = 10 mA to improve response time at higher power levels. The input pin INPT is flanked by the VSUM guard pins that track the voltage at the summing node. Connecting the exposed pad of the device to the VSUM pins provides a continuous guard to minimize leakage into the INPT pin. The default value of the logarithmic slope at the VLOG output is set by an internal 5 kΩ resistor. Logarithmic slope can be lowered with an external shunt resistor or increased using the buffer and a pair of external feedback resistors. The addition of a capacitor at the VLOG pin provides a simple low-pass filter. The intermediate voltage, VLOG, is buffered in an output stage that can swing to within about 100 mV of ground and the positive supply, VPS, and provides a peak current drive capacity of ±20 mA. An on-board 2 V reference is provided to facilitate the repositioning of the intercept. The incremental bandwidth of a translinear logarithmic amplifier inherently diminishes for small input currents. At IPD =1 nA, the bandwidth of the ADL5303 is approximately 2 kHz increasing in proportion to IPD up to a maximum value of 10 MHz.

(easYgen-3000)Please be aware about the following differences in comparison to the existing product lines:DC range of digital inputsThe easYgen-3000 voltage range for the discrete input DI is max 40VDC.instead of 18 to 250 VAC/DC (MFR 2 devices)Form factor from the digital outputsNot all relay outputs from the easYgen are galvanic isolated.Some outputs use the same common terminalConnection from the communication interfacesThe easYgen has “SUB-D connectors” for the communication interfaces instead of terminalblocks.ModBus visualizationIn the easYgen the start address from the visualization is 450001, the lower address rangeis used for the remote control and parameters.CAN Bus communication typeFor the CAN BUS communication the easYgen uses the CANOpen protocol instead of theCAN CAL protocol. With that it’s not possible to use the GW4 for the easYgen-3000.CAN Bus load sharingThe communication between the existing product s and easYgen (load sharing) requires theuse from the Load share gateway (LSG)Profibus DP slave communicationFor the Profibus connection between the easYgen and PLC an additional device isnecessary in order to convert the CAN Open or Modbus data to Profibus. Woodward offerssuch a gateway.Asynchronous applicationsA remanence voltage to MPU pulse converter is provided for sensing the RPM throughremanence voltage of an asynchronous generator.“THE INFORMATION CONTAINED IN THIS DOCUMENT IS PROVIDED AS IS WITHOUT REPRESENTATIONS OR WARRANTIES OF ANY KIND EXPRESSED OR IMPLIED.
