6ES7223-1BL22-0XA0 Siemens Digital Input And Output Modules SIMATIC S7-200 EM 223 24VDC

1.Overview of the 6ES7223-1BL22-0XA0 Siemens

The 6ES7223-1BL22-0XA0 is the classic EM 223 digital I/O module from the Siemens SIMATIC S7-200 series. It features 16 24V DC inputs and 16 24V DC transistor outputs. This single module adds 32 high-speed, highly reliable digital channels to the CPU, making it the most cost-effective solution for expanding small PLC systems. Utilizing industrial-grade components, the module draws 5V logic power directly from the backplane bus. On-site wiring requires only a 24V signal power supply, allowing installation, commissioning, and maintenance to be completed in less than 10 minutes.

Features:
32-point high-density: A single module replaces two EM 221 and EM 222 modules, saving rail space.
Transistor outputs: No contact life limit, support 100Hz high-speed switching, and support PWM/pulse applications. Bidirectional input: Accepts PNP/NPN sensors, providing flexible field wiring.
0.75 A direct drive capability: Directly drives solenoid valves, relays, and indicator lights without the need for intermediate relays.
Optical isolation: 500 V AC three-way isolation between channel, logic, and field, providing strong anti-interference capabilities.
Hot-swappable support: Modules can be replaced while the system is running, minimizing downtime.
Online configuration: STEP 7-Micro/WIN automatically identifies the address, eliminating the need for DIP switches.

High-Density I/O Configuration: This module provides 16 inputs and 16 outputs in a compact package, saving expansion slots in the S7-200 control system and improving system integration.

Flexible Sensor Connection: The 16 digital inputs support two-wire sensors (with a maximum closed-circuit current of 1 mA) and support both sourcing (current sourcing) and sinking (current sinking) wiring methods, ensuring high compatibility.

Fast Switching Frequency: The transistor outputs offer a fast response time, making them suitable for control applications requiring rapid response.

Built-in Potential Isolation: Both digital inputs and outputs utilize optocouplers for isolation. Inputs are grouped in groups of four points, while outputs are grouped in groups of 4, 4, or 8 points, enhancing system immunity and safety.

Convenient Installation and Maintenance: Plug-in terminals facilitate wiring and maintenance. The module connects to the right side of the S7-200 CPU or other expansion modules using the included I/O bus cable.
