SIEMENS S7 200 PLC CPU 226
The SIMATIC SIEMENS S7-200 PLC CPU226 with 32 IO module Supported. Which is S7-200 PLC S7-200 Analog module. The Siemens S7-200 PLC CPU 226 is a compact programmable logic controller (PLC) designed for small to medium-sized automation applications.
It comes in two variants you mentioned:
- CPU 226 DC/DC/DC (6ES7 216-2AD23-0XB0): This version has built-in DC power supply and all DC transistor outputs.
- CPU 226 AC/DC/RLY (6ES7 216-2BD23-0XB0): This version has a wider power supply range (AC/DC) and relay outputs.
- Compact design: Fits in tight spaces within control cabinets.
- Processing power: Suitable for handling control tasks in small to medium-sized machines.
- Memory:
- Program memory: Up to 24 KB for storing control programs.
- Data memory: Up to 10 KB for storing program variables.
Input/Output (I/O) Points:
- Built-in I/O: Both variants offer a range of built-in digital inputs and outputs for connecting sensors and actuators directly.
- Number of I/O points: The exact number depends on the specific model within the CPU 226 DC/DC/DC or CPU 226 AC/DC/RLY series. You’ll need to check the specific model number for details (e.g., CPU 226 DC/DC/DC 12/24 DI/DO indicates 12 digital inputs and 24 digital outputs).
- Expansion: Limited expansion capabilities compared to larger PLCs. Some models might allow adding a few additional I/O modules.
Communication:
- Built-in RS485 port for communication with other devices like HMIs (Human Machine Interfaces) and programming tools.
- Some models might also offer additional communication options like MPI (Multi-Point Interface) depending on the specific model.
Programming:
- Programmable with Siemens STEP 7 Basic software, a user-friendly platform suitable for ladder logic and statement list programming.
Typical Applications:
- Machine control (conveyors, material handling)
- Building automation (lighting, HVAC)
- Data acquisition and logging
- Process control (simple processes)
Choosing Between DC/DC/DC and AC/DC/RLY Variants:
- Power Supply:
- DC/DC/DC: Ideal for applications with a stable DC power supply available.
- AC/DC/RLY: Offers more flexibility with a wider AC/DC power supply range.
- Outputs:
- DC/DC/DC: All transistor outputs, suitable for low-power DC devices.
- AC/DC/RLY: Relay outputs, can handle higher power loads but have slower switching times compared to transistors.
Additional data:
The information above provides a general overview. For detailed specifications on memory capacity, I/O points, communication options, and expansion capabilities, refer to the datasheet for the specific model number within the CPU 226 DC/DC/DC or CPU 226 AC/DC/RLY series (available from Siemens or authorized distributors).
