Overview Manuals Specifications Application Firmware and Updates Configuration

Features:

  • SIMATIC S7-1200 CPU 1212C DC/DC/DC with 8 DI, 6 transistor DO, 2 AI and onboard PROFINET.
  • 6 high‑speed counters (HSC) up to 100 kHz; 4 high‑speed pulse train outputs (PTO) at 100 kHz; suitable for stepper/servo control.
  • Supports up to 3 communication modules, 1 signal board, 2 signal modules; memory expandable to 2 GB via SD card.
The 6ES7212-1AE40-0XB0 is a complete control solution in a 90 mm wide package. It integrates 8 digital inputs (24V DC), 6 digital outputs (0.5A each), and 2 analog inputs (0‑10V). This eliminates the need for separate I/O modules for basic applications, saving cabinet space and reducing hardware costs. The CPU has 50 KB of work memory for code and 1 MB of load memory, expandable to 2 GB via a SIMATIC memory card. Bit operation time is an impressive 0.085 µs, allowing fast ladder logic execution. The onboard PROFINET port (Ethernet) supports programming, HMI communication, and CPU‑to‑CPU data exchange.

The 6ES7212-1AE40-0XB0 includes built‑in high‑speed counters (HSC) and pulse train outputs (PTO), making it suitable for basic motion control without additional modules. Six of the digital inputs can be configured as HSC – three single‑phase inputs up to 100 kHz and three differential inputs up to 80 kHz. These can be used to measure speed, position, or frequency from incremental encoders. Four of the digital outputs can be configured as PTO at 100 kHz, directly controlling stepper drives or servo drives with pulse/direction signals. This capability is ideal for simple positioning tasks, such as indexing conveyors, cut‑to‑length machines, or pick‑and‑place units. The fast output delay (1 µs turn‑on, 3 µs turn‑off) ensures precise pulse timing.

Despite its compact size, the 6ES7212-1AE40-0XB0 offers significant expansion capabilities. It supports up to 3 communication modules (e.g., RS232, RS485, PROFIBUS, AS‑i), 1 signal board (e.g., additional analog I/O, digital I/O, or RS232 port), and 2 signal modules (standard S7-1200 I/O modules). This allows the system to grow from a small standalone PLC to a distributed control node. The load memory can be expanded to 2 GB using a SIMATIC memory card (SD card format), storing large programs, recipes, or data logs.

The Siemens 6ES7212-1AE40-0XB0 CPU 1212C DC/DC/DC is available for quotation, official-document access and sourcing support from Apter Power. OEM status and lead time are confirmed at inquiry.

Description
The 6ES7212-1AE40-0XB0 is a compact CPU 1212C for SIMATIC S7-1200 systems. It operates on 24V DC (20.4-28.8V) and features onboard I/O: 8 digital inputs, 6 digital outputs (0.5A each), and 2 analog inputs (0-10V). 

When using the 6ES7212-1AE40-0XB0, engineers benefit from 6 high-speed counters (HSC) on the inputs and 4 high-speed outputs (100 kHz pulse train) for motion control. Bit operation time is 0.085 µs. 

The 6ES7212-1AE40-0XB0 has a PROFINET interface with integrated Ethernet port supporting auto-negotiation and autocrossing. Programming requires STEP 7 V13 SP1 or higher. The CPU supports LAD, FBD, and SCL languages. It has 1,024 bytes each for I/O address area and adjustable process image. 

For small to medium automation tasks, the 6ES7212-1AE40-0XB0 provides a cost-effective solution.  Operating temperature is -20°C to 60°C horizontally (derated for vertical mounting). The CPU has no short-circuit protection on digital outputs – external fusing is required. It is ideal for conveyor control, packaging machines, and basic motion applications.
