Product Introduction
The Siemens 6ES7215-1BG40-0XB0 is a compact CPU from the SIMATIC S7-1200 series, designed for high-performance automation tasks. This CPU 1215C features an integrated AC power supply, relay outputs, and two PROFINET ports. With 125 KB of work memory and firmware V4.1, it delivers fast processing for complex control applications. The 6ES7215-1BG40-0XB0 combines digital and analog I/O in one unit, reducing system cost and panel space.
Technical Specifications Breakdown
The CPU operates on 85–264 V AC at 47–63 Hz, drawing 100 mA at 120 V AC. Its 14 digital inputs accept 24 V DC with programmable input delays from 0.2 ms to 12.8 ms. The 10 relay outputs switch up to 2 A resistive load. Two analog inputs measure 0–10 V DC with 10-bit resolution, and two analog outputs provide 0–20 mA DC. Memory includes 4 MB load memory (expandable via SIMATIC Memory Card) and 125 KB work memory.
Processing Performance
Bit operations execute in 0.085 µs, word operations in 1.7 µs, and floating-point arithmetic in 2.3 µs. The CPU supports up to 16 PROFINET IO devices and 8 positioning axes. Integrated functions include 6 high-speed counters (up to 100 kHz), PID controller, and frequency measurement.
Industry Applications
The 6ES7215-1BG40-0XB0 excels in machine building, packaging, and material handling systems. Its integrated I/O eliminates the need for separate modules in many cases, lowering total cost. For example, in a conveyor control system, the 14 digital inputs handle sensor feedback while the 10 relay outputs drive contactors, and the analog channels manage speed control. In building automation, the CPU can manage HVAC zones with PID loops and communicate via Modbus or PROFINET.
Compatibility & Integration
This Siemens 6ES7215-1BG40-0XB0 supports PROFINET IO (Controller and Device), PROFIBUS (via CM 1243-5), AS-Interface, and Ethernet protocols including TCP/IP, ISO-on-TCP, and UDP. It serves as an S7 communication server or client and hosts a configurable web server. The CPU integrates seamlessly with TIA Portal and STEP 7 V13 SP1 or higher.
Selection Guide & Purchasing Advice
When selecting the 6ES7215-1BG40-0XB0, verify your power supply matches AC 85–264 V and confirm I/O count requirements. Consider ordering a SIMATIC Memory Card for expanded load memory. For reliable procurement, source this Siemens 6ES7215-1BG40-0XB0 from PLC Source PRO (formerly ubest101), a trusted distributor of industrial automation spares. Always check firmware version compatibility with your project.
