SIEMENS 6ES7223-1BL22-0XA0 Digital I/O Module

Product Description

The SIEMENS 6ES7223-1BL22-0XA0 is a digital input/output (I/O) module from the SIMATIC S7-200 series, designed for industrial automation applications. It provides 16 digital inputs (24V DC) and 16 digital outputs (24V DC, 0.75A per channel), making it ideal for machine control, process automation, and distributed I/O systems. The module supports sink/source (PNP/NPN) wiring and is compatible with S7-22X CPUs, offering flexible integration in control cabinets .

Key Features & Advantages

High-Density I/O Configuration
- 16 digital inputs (DI): Supports 24V DC signals with 4.5ms max input delay for stable signal processing .
- 16 digital outputs (DO): Transistor-based (0.75A per channel), suitable for driving relays, solenoids, and small motors .
Robust Industrial Design
- DIN rail mounting (137.5 × 80 × 62 mm) for easy installation in control panels .
- IP20 protection against dust and accidental contact .
- Wide operating temperature range (0°C to +55°C) for harsh environments .
Flexible Connectivity
- Supports sink/source (PNP/NPN) wiring for compatibility with various sensors and actuators.
- Shielded cable support (up to 500m) for noise reduction in industrial networks .
Integrated Diagnostics & Safety
- Optocoupler isolation between channels (grouped in 4s) to prevent ground loops .
- Short-circuit and overload protection for outputs .
Compatibility & Expandability
- Works with S7-200 CN/S7-22X CPUs and can be expanded with additional modules .
- Plug-and-play terminal blocks for quick wiring .
