Information About TXS1.12F10

The TXS1.12F10 is a DIN rail-mountable power supply designed for the Siemens TX-I/O product line, commonly used in HVAC and building automation. It accepts 24 VAC input at 50/60 Hz and delivers a regulated 24 VDC output at 1.2 A (28.8 W) to power TX-I/O modules and field-connected sensors or actuators. In addition, it provides AC pass-through at 24 VAC (144 VA) for directly supplying field devices that operate on AC. The module also transfers the bus signal, maintaining communication integrity within the TX-I/O system. Designed with IP20 (or IP30 in cabinet) rated enclosure, the device meets Class 2 safety standards and allows up to 4 units to operate in parallel for increased power demands or redundancy.

Key Features:

• Input Voltage: 24 VAC at 50/60 Hz, 57 VA for internal operation.
• DC Output: 24 VDC at 1.2 A (28.8 W) for TX-I/O modules and field devices.
• AC Pass-Through: 24 VAC, 144 VA for direct field device supply.
• Parallel Operation: Up to 4 modules can be used in parallel for scalable power delivery.
• Signal Transfer: Maintains TX-I/O bus signal integrity.
• Enclosure Rating: IP20 for panel use (IP30 when installed in suitable enclosure).
• Safety Class: Class 2 compliant.
  

The TXS1.12F10 offers efficient, modular power delivery and signal continuity for decentralized I/O in intelligent building control systems.
