The Siemens 6ES7223-1PH32-0XB0 is a DC-input/relay-output combination module for the S7-1200 system, providing 8 relay outputs and digital inputs in a 45 mm-wide housing. Rated for -40 to 70 °C, it carries cULus, CE, FM, KC, UL, CSA, marine, and RCM approvals—covering most global panel requirements.
Input/output characteristics
Inputs switch at a 15 V DC threshold (signal '1', 2.5 mA), compatible with standard 24 V DC sensors. Outputs handle 5–250 V AC or 5–30 V DC relay loads, up to 30 W DC / 200 W AC on lamp loads. Cabling distances: 500 m shielded, 150 m unshielded. Power draw is 5.5 W typical.
Lifecycle & sourcing
Marked as current production. Available through standard Siemens distribution channels. For BOM-frozen projects, confirm lead time against your schedule.
