Product description

The Siemens 6ES7 512-1DK01-0AB0 is a central processing unit in the CPU 1512SP-1 PN series within the SIMATIC ET 200SP distributed I/O system. Siemens classifies the module as a SIMATIC DP CPU. The integrated work memory provides 200 KB for the user program and 1 MB for data. A SIMATIC Memory Card with a capacity of up to 32 GB serves as pluggable load memory; this memory card is required for operation. The first communication interface supports PROFINET IRT and is designed as a 3-port switch. A separate BusAdapter is required for ports 1 and 2. Typical processing times are 48 ns for bit operations, 58 ns for word operations, 77 ns for fixed-point arithmetic and 307 ns for floating-point arithmetic. The rated current is 0.6 A and the maximum input current is 0.9 A. Siemens documents a typical power loss of 5.6 W. The retentive data area has a maximum capacity of 128 KB, with 88 KB allocated to flags, timers, counters, data blocks and technology data. The peripheral address space is 32 KB each for inputs and outputs. The specified operating temperature range is -25 to 60 °C for horizontal installation and up to 50 °C for vertical installation. The module is 100 mm wide, 117 mm high and 75 mm deep. Its documented device weight is approximately 310 g. The complete order number 6ES7512-1DK01-0AB0 identifies this specific memory, interface and performance version. Siemens has listed the product as a discontinued spare part since 1 October 2024 and identifies 6ES7512-1DM03-0AB0 as the subsequent product.
