Operating within the modular EtherCAT I\/O system, this terminal supports differential signal acquisition in the range of -10 to +10 V with 16-bit resolution. It is engineered specifically for dynamic measurement tasks requiring synchronous, high-frequency data collection across distributed control systems.\u003c\/p\u003e\n\n\u003cp\u003eA key capability of the BECKHOFF EL3702 is its support for oversampling technology. This allows the terminal to sample analog input values at rates far higher than the master control cycle time. By utilizing EtherCAT Distributed Clocks (DC), the acquired measurements are precisely timestamped and synchronized across the network with sub-microsecond precision, making it an excellent choice for detailed signal analysis and transient state monitoring.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo differential analog input channels designed for ±10 V voltage signals.\u003c\/li\u003e\n  \u003cli\u003eOversampling technology with a selectable factor (n = 1 to 100) for custom data acquisition profiles.\u003c\/li\u003e\n  \u003cli\u003eMaximum sampling rate of 10 microseconds (100 ksamples\/s) per channel, executed simultaneously.\u003c\/li\u003e\n  \u003cli\u003e16-bit analog-to-digital conversion resolution (including sign) for high-fidelity signal reconstruction.\u003c\/li\u003e\n  \u003cli\u003eIntegrated Distributed Clocks (DC) support, delivering synchronization precision of less than 1 microsecond.\u003c\/li\u003e\n  \u003cli\u003e500 V electrical isolation between the E-bus logic and the incoming signal voltage.\u003c\/li\u003e\n  \u003cli\u003eCompact 12 mm housing with status LEDs indicating operational and diagnostic states.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-speed transient signal and wave recording.\u003c\/li\u003e\n  \u003cli\u003eVibration analysis, acoustic measurement, and structural health monitoring.\u003c\/li\u003e\n  \u003cli\u003eDynamic force, pressure, or torque monitoring in test benches.\u003c\/li\u003e\n  \u003cli\u003eFast closed-loop control systems where low-latency feedback is critical.\u003c\/li\u003e\n  \u003cli\u003eQuality control systems requiring high-frequency sensor signal analysis.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ch4\u003eGeneral\u003c\/h4\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eParameter\u003c\/th\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eManufacturer\u003c\/td\u003e\n      \u003ctd\u003eBECKHOFF\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eModel\u003c\/td\u003e\n      \u003ctd\u003eEL3702\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Type\u003c\/td\u003e\n      \u003ctd\u003eEtherCAT Terminal\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDesign Form\u003c\/td\u003e\n      \u003ctd\u003eCompact terminal housing with signal LEDs\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMaterial\u003c\/td\u003e\n      \u003ctd\u003ePolycarbonate\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDimensions (W x H x D)\u003c\/td\u003e\n      \u003ctd\u003e12 mm x 100 mm x 68 mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eInstallation\u003c\/td\u003e\n      \u003ctd\u003e35 mm DIN rail (EN 60715) with locking mechanism\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWeight\u003c\/td\u003e\n      \u003ctd\u003eApprox. 60 g\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch4\u003eSignal and I\/O\u003c\/h4\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eParameter\u003c\/th\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNumber of Inputs\u003c\/td\u003e\n      \u003ctd\u003e2 (differential)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSignal Type\u003c\/td\u003e\n      \u003ctd\u003eDifferential voltage\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSignal Voltage Range\u003c\/td\u003e\n      \u003ctd\u003e-10 V to +10 V\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eInternal Resistance\u003c\/td\u003e\n      \u003ctd\u003e\u0026gt;
