Product Overview: 6ES7223-1PL32-0XB0
The Siemens 6ES7223-1PL32-0XB0 is a versatile **Digital Input/Output Module (SM 1223)** for the SIMATIC S7-1200 PLC series. It combines **16 Digital Inputs** and **16 Digital Outputs** in a single device, doubling the I/O capacity without occupying multiple slots on the DIN rail.
Technical Specifications
| Inputs | 16 DI (24 V DC, Sink/Source) |
| Outputs | 16 DO (Relays) |
| Switching Capacity | 2 A per Relay Output |
| Isolation | Yes (Optocoupler / Relay coil) |
Advantages of Relay Outputs
Unlike transistor outputs, the **Relay Outputs** of the 6ES7223-1PL32-0XB0 allow for the switching of different voltage potentials (e.g., 230V AC or 24V DC) directly, up to 2 Amps. This makes it extremely flexible for controlling mixed loads like solenoid valves, contactors, and pilot lights.
Installation
The module snaps onto the standard 35mm DIN rail next to the CPU. It is automatically recognized by TIA Portal software. Ensure strict separation of low voltage and high voltage wiring to prevent interference.
