CPU 1214C DC/DC/DC Project Overview
The 6ES7214-1AG40-0XB0 CPU 1214C brings twenty-four onboard digital points, two voltage analog inputs and fast transistor switching into a compact S7-1200 controller. Its 150 KB program/data memory and integrated PROFINET interface support capable machine-control projects without pushing every signal into expansion hardware.
Engineering Decision Points
Output speed
Transistor outputs suit high-cycle DC loads and pulse-oriented machine functions.
I/O density
Fourteen inputs and ten outputs cover a useful portion of a compact machine before expansion.
Project headroom
150 KB of work memory allows a larger control program than 1211C and 1212C CPUs.
Electrical boundary
Loads must fit the 24 V DC transistor architecture and documented channel/group limits.
Product View and Selection Boundary

Before you specify this MLFB
Choose this DC/DC/DC variant when the control supply and output loads are 24 V DC. It is the fastest-switching 1214C option in this set, but it does not provide relay isolation for mixed-voltage loads.
Verified Technical Data
Commissioning Timeline
- 01Confirm the full MLFB, firmware and 24 V DC supply design.
- 02Map all onboard DI, DQ and AI channels with common and protection details.
- 03Create the CPU and PROFINET identity in the supported TIA Portal project.
- 04Commission outputs under real load, review diagnostics and archive the final project.
