6ES7223-1BL32-0XB0 Siemens SIMATIC S7-1200 Digital I/O SM 1223 16 DI 24 V DC

Product Name:

Siemens SIMATIC S7-1200, Digital I/O Module SM 1223, Model 6ES7223-1BL32-0XB0
Application: Digital signal acquisition and execution control in industrial automation systems, used to expand the local I/O capacity of the S7-1200 PLC.

I. Core Functions
- 32 digital channels: 16 digital inputs (DI) + 16 digital outputs (DO), suitable for high-I/O density applications.
- 24 VDC standard voltage: Inputs are IEC 61131-2 Type 1 compliant, and outputs are transistor-type, 0.5 A per channel.
- Flexible parameterization: Input filtering is adjustable from 0.2 to 12.8 ms, supporting high-speed counting and alarm interrupts. - Channel group isolation: 2 input groups × 8 channels, 1 output group × 16 channels, isolated from the backplane bus at AC 500 V, providing strong anti-interference capabilities.
- Status LED: Independent green LED for each channel for quick on-site diagnostics.
