SIEMENS 216-2AD23-0XB0 Product Description

Overview

SIEMENS 216-2AD23-0XB0 corresponds to the Siemens SIMATIC S7-200 CPU 6ES7 216-2AD23-0XB0, identified in Siemens and public datasheet records as CPU 226 compact unit with DC power supply, 24 DC digital inputs and 16 DC digital outputs. It is an integrated PLC CPU for existing S7-200 control systems, providing program memory, digital I/O and two PPI or Freeport communication ports.

Features

The CPU 226 compact unit is supplied from 24 V DC, with permissible DC upper limit 28.8 V and maximum inrush current 10 A at 28.8 V. Supply current from L+ is listed at maximum 1050 mA, including up to 150 mA to 1050 mA output current for expansion modules at 5 V DC and 1000 mA CPU reference. The 24 V DC sensor supply has permissible range 15.4 to 28.8 V and maximum output current 400 mA.

Integrated program memory is 24 kbyte, with 16 KB available when run-time editing is active. Integrated data memory is 10 kbyte. One optional pluggable memory module can be added; its content is identical to the integral EEPROM and can additionally store recipes, data logs and other files. The entire program is maintained maintenance-free in integral EEPROM. Data DB 1 loaded from PG or PC is maintained in integral EEPROM, while current DB 1 values, retentive memory bits, timers and counters are retained through a high-performance capacitor or optional battery.

Backup time is listed at maximum 100 h, minimum 70 h at 40 degrees Celsius, and 200 days typical with optional battery module. The CPU provides two PPI or Freeport interfaces according to the Siemens CPU 226 compact unit record.

Principle

The CPU 226 executes the S7-200 user control program, reads integrated digital input states, processes logic, timers, counters, arithmetic, communication and control functions, and switches the integrated digital outputs according to the program. The 24 V DC supply powers the CPU and sensor supply; expansion modules can be connected to extend I/O or communication capacity.

The two PPI or Freeport ports support programming device connection, HMI or operator panel communication, and serial Freeport communication with other devices. Memory retention stores the program and selected retentive data after power removal. The capacitor provides a limited backup period; the optional battery module extends retention for long-term power-off storage.

Replacement should verify the original CPU order number, supply voltage, input and output wiring, expansion module configuration, program version, retentive data, communication port assignment, PPI or Freeport parameters, memory module, battery or capacitor condition, and PLC backup before removal. S7-200 is a legacy Siemens platform; replacement compatibility, program transfer and commissioning should follow Siemens S7-200 documentation and the site PLC change-control procedure.

Applications

SIEMENS 216-2AD23-0XB0 is used in existing SIMATIC S7-200 PLC installations on industrial machines, production lines, packaging equipment, conveyors, material handling, machine tools, pumps, fans, compressors, process panels, textile or printing machinery, utilities, marine auxiliary controls and general automation retrofit systems. In legacy S7-200 panels, the CPU serves as a direct replacement spare when the supply voltage, integrated I/O configuration, expansion modules, program, memory and communication settings match the original CPU.
