Siemens sITAS Series DIN Rail Transformer, 250VA Power, 230V Primary Voltage - 4AM4042-4TT10-0FA0


This DIN rail transformer is a Compact control-circuit device designed to provide galvanically separated power in panel and automation installations. It accepts a nominal 230V supply and delivers a single 230V output while operating across standard industrial frequency ranges, making it suitable for use where an isolated, low-power secondary supply is required.

Features & Benefits


• 230V to 230V ratio for direct isolation in control circuits
• Operates at 50–60 Hz to suit varied supply systems
• Screw terminals and tab connections simplify wiring
• Efficiency 0.89 reduces internal losses during operation

**Applications**


• Suitable for control panels requiring an isolated 230V supply
• Ideal for industrial automation control-circuit isolation
• Used with relay and PLC input circuits needing galvanic separation
• Can be used for small machinery control-power distribution

What mounting options are provided for panel fitting?


It can be secured using screws or clipped onto DIN rails for straightforward panel integration.

How does it behave under short-term overload?


The transformer supports a short-term Vector power of 850 VA for transient conditions while rated continuous apparent power remains 250 VA.

What Terminal types are available for main connections?


Both screw-type terminals and tab terminals are provided for input and output main circuits to accommodate varied wiring practices.

Which thermal rating and ambient limit apply during continuous use?


The winding insulation is rated to thermal class B and the device is specified for an ambient temperature limit of 40°C.
