This voltage output is logic-switch controlled, allowing 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\u003eSignal filtering is accomplished with a six-pole filter which provides 95dB of normal-mode rejection at 60Hz and 90dB at 50Hz. Two poles of this filter are on the field side of the isolation barrier, and the other four are on the computer side.\u003cbr\u003e\u003cbr\u003eAfter the initial field-side filtering, 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\u003eA special input circuit on the SCM5B30 and SCM5B31 modules provides protection against accidental connection of power-line voltages 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\u003eAccepts Millivolt and Voltage Level Signals\u003c\/li\u003e\n\u003cli\u003eHigh-Level Voltage Outputs\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\u003e160dB CMR\u003c\/li\u003e\n\u003cli\u003e95dB NMR at 60Hz, 90dB at 50Hz\u003c\/li\u003e\n\u003cli\u003e±0.03% Accuracy\u003c\/li\u003e\n\u003cli\u003e±0.005% 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\/scm5b30_31.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":53702925091153,"sku":null,"price":59.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0942\/9522\/8753\/files\/A5497FA0-BFF0-4811-80C0-29E420300775.png?v=1778501762","url":"https:\/\/www.outlecta.com\/products\/dataforth-scm5b31-04","provider":"Outlecta.com","version":"1.0","type":"link"}
