SIMATIC S7-1200 G2, Digital I/O, SM 1226, F-DI 4x / F-DQ 2x 2A PPM / DI 2x, 24VDC, up to PL E (ISO 13849-1) / SIL3 (IEC 61508). With the new fail-safe S7-1200 G2 signal module SM 1226 F-DI 4x / F-DQ 2x 2A PPM / DI 2x, 24VDC, Siemens offers its users an entry into the functional safety of the new SIMATIC controller generation S7-1200 G2. The SM 1226 sets new standards and enables a significantly more compact design compared to the previous version SIMATIC S7-1200. The space requirement on the DIN rail is reduced by almost 60% to 30 mm when comparing module widths. By combining F-DI and F-DQ in the SM 1226, an 80% reduction in space requirement compared to the SIMATIC S7-1200 has even been achieved.
