The 6AG1500-0JT00-4AB0 is the SIPLUS version of the S7-1500 CPU 1518HF system bundle, built for redundant high-availability applications in harsh environments. Conformal coating protects the boards against humidity, dust and aggressive gases. The bundle includes two CPU 1518HF-4 PN units, four sync submodules rated for optical link distances up to 200 m, and two 1 m fiber-optic sync cables — everything needed to wire a redundant pair except the memory card.
RoHS compliance effective 01-06-25; REACH candidate list information available on request.
The bundle is designed for a redundant CPU configuration: two CPUs run in lockstep, synchronised over the dedicated fiber-optic links. The sync submodules plug into the CPU front and connect to each other via the included 1 m FOC cables. No memory card is included — order a SIMATIC memory card separately for each CPU. The conformal coating adds environmental resistance, making this a candidate for installations with condensation, salt mist, or volatile chemicals where standard S7-1500 CPUs would not be specified.
