Siemens 6ES7214-2BD23-0XB0 Programmable Logic Controller Module

Siemens 6ES7214-2BD23-0XB0 is a SIMATIC S7-200 CPU 224XP Compact Unit with 14 digital inputs (DC 24 V), 10 relay outputs, 2 analog inputs, and 1 analog output, all integrated in a single CPU module. It offers two PPI ports for user-programmable communication, and is powered by an AC supply selectable between 120 V AC or 230 V AC, with a 24 V DC load supply (5–30 V) and L1 rated at 100 V AC (range 5–250 V, 47–63 Hz). The device carries 12/16 KB of program memory and 10 KB of data memory, with an optional pluggable memory module and EEPROM-backed program retention; backup is provided via EEPROM and a capacitive buffer, with an optional battery for long-term use. Typical power consumption is around 11 W, and the unit includes electronic short-circuit protection at 280 mA. As part of the S7-200 family, the CPU 224XP is commonly used in compact automation tasks such as small machines, conveyors, and packaging lines where discrete I/O plus basic analog interfacing are required.
