Overview

The Siemens 6ES7223-1BL32-0XB0 is a compact and high-density digital I/O expansion module designed for the Siemens SIMATIC S7-1200 PLC series. It integrates 16 digital inputs and 16 digital transistor outputs in a single module, enabling efficient control and monitoring for medium-sized industrial automation systems. Operating on 24 V DC, the module delivers reliable signal processing, low power consumption, and stable performance in demanding industrial environments.

Compared with lower-density modules such as SM 1231 and SM 1232, the SM 1223 significantly increases I/O capacity without enlarging the PLC installation footprint, making it ideal for compact automation architectures.

Functions

Provides 16 digital inputs for receiving field signals from sensors, switches, and control devices.
Provides 16 digital transistor outputs for controlling actuators, relays, solenoids, indicators, and other field equipment.
Supports reliable 24 V DC signal detection with high noise immunity.
Enables both sinking and sourcing output applications for flexible industrial integration.
Expands the I/O capability of Siemens S7-1200 PLC systems without requiring additional controller hardware.
Ensures electrical isolation between channels and the backplane bus for enhanced system protection and operational safety.

Features

High-density 16 DI / 16 DO configuration for space-saving PLC expansion.
Stable 24 V DC operation with a permissible voltage range of 20.4 V to 28.8 V.
Low power consumption with typical power loss of only 4.5 W.
Fast and accurate digital signal recognition:
- Logic “0”: 5 V DC at 1 mA
- Logic “1”: 15 V DC at 2.5 mA
Transistor outputs capable of handling up to 0.5 A per channel.
Maximum backplane current consumption of 185 mA.
500 V AC electrical isolation between channels and backplane bus.
Compact and lightweight design:
- Dimensions: approximately 7 × 7.5 × 10 cm
- Weight: 0.26 kg
Designed for high reliability in harsh industrial conditions.
Manufactured in Germany with Siemens industrial quality standards.
