{ "@context" : "http://schema.org/", "@type" : "Product", "name" : "Fail-safe 4 channel analog input; 0/4 … 20 mA; Differential input; PROFIsafe", "description" : "<p>The 75x-668/000-004 Module features four differential fail-safe analog inputs (AI1 … AI4) and four current-limited sensor supply outputs (L1 … L4). The sensors can be supplied directly by the module or via external 24 V. The fail-safe analog inputs can be used either in single-channel (up to SIL2/PLd) or dual-channel mode (up to SIL3/PLe). Measurement cycle, filter times, encoder evaluation with discrepancy times and tolerance windows can be adjusted to meet the safety function requirements.</p><p>Overcurrent, overload and wire break are monitored at the fail-safe analog inputs. Both the monitoring and additional safety-relevant functions can be parameterized via WAGO-I/O-<i>CHECK</i>.</p><p>This configuration tool can be conveniently integrated into engineering systems supporting TCI (Tool Calling Interface) with CC2 or CC3.</p><p>When exchanging a module, parameters are automatically downloaded from the controller via PROFIsafe-compatible iPar server.</p><p>The PROFIsafe address can be set using the DIP switch or via WAGO-I/O-<i>CHECK</i>.</p><p>The module supports both PROFIsafe V2.4 (PROFIBUS, PROFINET) and V2.6 (PROFINET) protocols.</p><p>Individual input modules can be arranged in any combination when configuring the fieldbus node.</p><p><b>If, for example, the cable length of the 24 V supply is greater than 3 m, a WAGO Filter Module or an appropriate external filter must be used for the 24 V power supply to protect the module against surge and burst (per IEC 61000-6-7 and marine applications).</b></p><p><b>Additional information can be found in the product manual (available in German and English)!</b></p>", "mpn" : "753-668/000-004", "sku" : "753-668/000-004", "brand" : { "@type":"Brand", "name":"WAGO" }, "manufacturer" : { "@type":"Organization", "name":"WAGO Kontakttechnik GmbH & Co.
