6ES7223-1PH32-0XB0 SM 1223 8DI/8DO Relay I/O Module 2A | Siemens

The Original New Siemens 6ES7223-1PH32-0XB0 SIMATIC S7-1200 SM 1223 Digital I/O Module provides 8 digital inputs and 8 relay outputs in a single compact signal module. Designed for flexible signal management in industrial automation systems, it enables seamless expansion of S7-1200 PLC I/O capacity for machine control, conveyor systems, packaging equipment, and factory automation applications where relay switching is required.

Core Engineering Highlights:
8 digital inputs (24V DC, sink/source, Type 1) | 8 relay outputs (2A per channel) | 145 mA backplane bus current | 2.5 W typical power loss | 2 isolated groups of relay outputs (4 outputs per group) | 1500V AC isolation (channel to backplane) | 45 x 100 x 75 mm | IP20 | –20°C to +60°C horizontal operation

Key Features:

• Original New Siemens 6ES7223-1PH32-0XB0 module

• 8 digital inputs, 24V DC, sink/source configurable (IEC 61131 Type 1)

• 8 relay outputs (normally open, 2A per channel)

• Inputs isolated in groups of 2 for reliable signal acquisition

• Relay outputs in 2 isolated groups of 4 outputs each

• 1500V AC isolation between channels and backplane

• LED status indicators for each input and output channel

• Removable terminal block connector (included) for easy wiring

• DIN rail mounting for space-efficient installation

• Horizontal or vertical mounting orientation options

• Compact 45 mm width for control cabinet space savings
