Replacement Guidance

If this unit is being sourced as a spare for an existing LOGO! 12 V system, the successor 6EP3321-6SB00-0AY0 is mechanically and electrically compatible. For new 12 V applications, also consider the SITOP PSU100C 6EP1322-5BA10 which provides 12 V at 6.5 A (78 W) for larger 12 V loads.
