The Siemens SIMATIC S7-200 6ES7223-1PL22-0XA8 is a digital input/output expansion module from the SIMATIC S7-200 CN series, designed exclusively for use with S7-22X CPUs. This unit provides substantial I/O expansion, integrating 16 digital inputs and 16 relay outputs into a single compact module, which greatly enhances the controller's interface capabilities without requiring excessive cabinet space.

A key feature of the 6ES7223-1PL22-0XA8 EM223 Siemens Digital I/O Module is its flexible 24 V DC inputs, which support both sink and source wiring configurations. This design simplifies installation and offers compatibility with a wide range of industrial sensors and field devices. The inputs have a low typical current consumption of 4 mA per channel for a signal "1", contributing to efficient overall system power management.

The SIEMENS Programmable Controller 6ES7223-1PL22-0XA8's 16 relay outputs are a significant advantage, with each channel capable of switching up to 2 A. This high-current capacity allows the DIGITAL I/O EM 223 Siemens 6ES7223-1PL22-0XA8 to directly control various actuators, such as contactors, solenoid valves, and indicator lights, reducing the need for additional interposing relays. It is important to note that these outputs do not have built-in short-circuit protection, which must be considered in the overall circuit design.

With compact dimensions of 137.5 mm in width and 80 mm in height, the Siemens 6ES7223-1PL22-0XA8  Digital Combo module is engineered for space-efficient mounting on a standard DIN rail. Certified with CE approval, this module is a reliable and high-density I/O expansion solution, characterized by its typical power loss of 6 W, making it a practical choice for expanding the capabilities of S7-200 CN control systems in diverse automation applications.
