Siemens 6ES7215-1HG40-0XB0 S7-1200 CPU 1215C Programmable Logic Controller

Product Overview

The Siemens 6ES7215-1HG40-0XB0 is a CPU 1215C module from the SIMATIC S7-1200 family of compact programmable logic controllers. It integrates a power supply, CPU, 14 digital inputs, 10 digital relay outputs, and 2 analog inputs in a single housing. This model operates at 24 V DC and is designed for small to medium-scale automation tasks such as machine control, conveyor systems, and building automation. The S7-1200 series is known for its flexibility, communication capabilities, and programming with TIA Portal software.

Key Features of CPU 1215C

The CPU features 14 onboard digital inputs (24 V DC, sink/source), 10 digital outputs (relay, 2 A @ 240 V AC), and 2 analog inputs (0-10 V, 0-20 mA, 10-bit resolution). It includes a PROFINET port (Ethernet) for programming and communication with HMIs, drives, and other PLCs. The processor executes user program in ladder, FBD, or SCL with a program memory of 100 KB and data memory of 1 MB. It has a built-in real-time clock and can support up to three communication modules and one signal board.

The CPU 1215C has a high-speed counter (6 channels, up to 100 kHz), pulse outputs (4 channels, 100 kHz) for stepper/servo control, and PID functionality. It includes a web server for remote monitoring. The unit has a removable terminal block for I/O connections. It operates at 24 V DC power supply (20.4-28.8 V). The operating temperature range is -20 to +60°C. The module is certified for CE, UL, and cULus.

Functional Description

The CPU executes the user program cyclically, reading inputs, solving logic, and updating outputs. The PROFINET port supports communication with TIA Portal for programming and with HMIs for operator interface. The high-speed counters can measure encoder pulses for positioning. The analog inputs can read sensor signals such as temperature or pressure. The PID block can regulate a process variable. The web server allows status viewing via a browser.

Applications

The 6ES7215-1HG40-0XB0 is used in small to mid-size machine control, packaging equipment, HVAC systems, and conveyor control. The relay outputs are suitable for AC loads.
