Product description
Siemens 6ES7 326-1BK02-0AB0 is a fail-safe digital input module from the SIMATIC S7-300 Safety Integrated range. Its module role is SM 326 F-DI, and it is assigned to SIMATIC S7 F-systems. The module has 24 digital inputs for an input voltage of 24 V DC. Fail-safe signal acquisition is documented as the safety function. A diagnostic alarm supports detection of reported module or channel states within the configured controller. Siemens lists safety requirements up to Category 4 according to EN 954-1, SIL 3 according to IEC 61508 and Performance Level e according to ISO 13849. These classifications refer to the correspondingly designed and parameterized safety application. Electrical front connection uses a 40-pole front connector. Channel parameters, F-destination address, discrepancy times, sensor evaluation and diagnostic settings belong to plant-specific engineering and are not part of the mechanical product dimensions. For control-cabinet and module planning, the exact Siemens data sheet specifies a width of 80 mm, a height of 125 mm and a depth of 120 mm. In consistent width × height × depth order, complete external dimensions are therefore 80 × 125 × 120 mm. Device weight is stated as approximately 442 g. Dimensions and weight refer to the individual module without front connector, wiring or shipping packaging. Exact order number, module role, channel count, signal voltage, safety classification and enclosure format distinguish this SM-326 version from similarly named standard or safety modules. The specification table concludes with Dimensions and Weight.
