This voltage output is logic switch controlled, which allows these modules to share a common analog bus without the requirement of external multiplexers.\u003cbr\u003e\u003cbr\u003eThe SCM5B modules are designed with a completely isolated computer side circuit which can be floated to ±50V from Power Common, pin 16. This complete isolation means that no connection is required between I\/O Common and Power Common for proper operation of the output switch. If desired, the output switch can be turned on continuously by simply connecting pin 22, the Read-Enable pin, to I\/O Common, pin 19.\u003cbr\u003e\u003cbr\u003eThe SCM5B38 can interface to full-bridge or half-bridge transducers with a nominal resistance of 100 Ohm to 10 kOhm. A matched pair of bridge-completion resistors (to ±1mV at +10V excitation) allows use of low cost half-bridge or quarter-bridge transducers (Figures 2, 3, 4). The 10kHz bandwidth allows measurement of high speed processes such as vibration analysis.\u003cbr\u003e\u003cbr\u003eStrain gage excitation is provided from the module by a very stable 10V or 3.333V source. The excitation supply is fully isolated, allowing the amplifier inputs to operate over the full range of the excitation voltage. This feature offers significant flexibility in real world applications. Full scale sensitivities of 2mV\/V, 3mV\/V or 10mV\/V are offered as standard. With 10V excitation, this results in ±20mV, ±30mV or ±100mV full scale input range producing ± 5V full scale output.\u003cbr\u003e\u003cbr\u003eThe input signal is processed through a pre-amplifier on the field side of the isolation barrier. This pre-amplifier has a gain-bandwidth product of 5MHz and is bandwidth limited to 10kHz. After amplification, the input signal is chopped by a proprietary chopper circuit. Isolation is provided by transformer coupling, again using a proprietary technique to suppress transmission of common mode spikes or surges. The module is powered from +5VDC, ±5%.\u003cbr\u003e\u003cbr\u003eSpecial input circuits on the SCM5B38 module provide protection of the signal inputs and the isolated excitation supply up to 240VAC.\u003c\/div\u003e\n\u003cdiv id=\"section_features\" class=\"mt-3\"\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cp class=\"fs-sm\"\u003e \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eInterfaces to 100 Ohm Thru 10 kOhm, Full-Bridge, Half-Bridge, or Quarter-Bridge Strain Gages\u003c\/li\u003e\n\u003cli\u003eHigh-Level Voltage Output\u003c\/li\u003e\n\u003cli\u003e1500Vrms Transformer Isolation\u003c\/li\u003e\n\u003cli\u003eANSI\/IEEE C37.90.1 Transient Protection\u003c\/li\u003e\n\u003cli\u003eInput Protected to 240VAC Continuous\u003c\/li\u003e\n\u003cli\u003eFully Isolated Excitation Supply\u003c\/li\u003e\n\u003cli\u003e100dB CMR\u003c\/li\u003e\n\u003cli\u003e10kHz Signal Bandwidth\u003c\/li\u003e\n\u003cli\u003e±0.03% Accuracy\u003c\/li\u003e\n\u003cli\u003e±0.01% Linearity\u003c\/li\u003e\n\u003cli\u003e±1µV\/°C Drift\u003c\/li\u003e\n\u003cli\u003eCSA Certified, FM Approved, CE and ATEX Compliant\u003c\/li\u003e\n\u003cli\u003eMix and Match SCM5B Types on Backpanel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"section_blockdiagram\" class=\"mt-3\"\u003e\n\u003ch3\u003eBlock Diagram\u003c\/h3\u003e\n\u003cimg src=\"https:\/\/www.dataforth.com\/media\/blockdiagram-images\/scm5b\/scm5b38.png\" alt=\"\"\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"section_techdocs\" class=\"mt-3\"\u003e\n\u003ch3\u003eDocuments\u003c\/h3\u003e\n\u003c\/div\u003e","brand":"Outlecta.com","offers":[{"title":"Default Title","offer_id":53703006716241,"sku":null,"price":59.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0942\/9522\/8753\/files\/IMG-3375.png?v=1778503191","url":"https:\/\/www.outlecta.com\/products\/dataforth-scm5b38-03","provider":"Outlecta.com","version":"1.0","type":"link"}
