The SITOP LOGO!Power EX 6EP3333-6SC00-0AY0 solves a specific panel-building challenge: getting regulated 24VDC power inside a hazardous-area enclosure without wasting space. Its stepped-profile housing is mechanically identical to a LOGO!8 PLC — the two devices stack flush on the same DIN rail, consuming no extra depth in a shallow cabinet. ATEX Zone 2 certification means the power supply itself is approved for installation inside the controlled zone, eliminating the need for a separate safe-area power enclosure and long cable runs to the load.

Electrical Performance

The module accepts a universal 100-240VAC input (50/60Hz, also 110-300VDC) and delivers a regulated 24VDC output at up to 4A continuous — 96W of usable power for the LOGO!8 CPU, expansion modules, sensors, and small actuators. Efficiency reaches 89.1% at rated load, keeping heat dissipation manageable inside enclosures where active cooling is rarely practical. Short-circuit and overload protection with automatic recovery are built in, and the output is galvanically isolated (SELV) per EN 60950-1.

Mechanical Integration

At 72mm wide, 90mm tall, and just 53mm deep, the module protrudes barely 5cm from the back panel — critical when cabinets are depth-constrained. The flat front face carries no protruding heatsinks or connectors beyond the terminal blocks. DIN rail snap-on mounting (EN 60715) and screw terminals for input and output wiring round out the installation. Net weight is approximately 0.3kg.

Key Decision Parameters

This module is part of the SITOP LOGO!Power family designed specifically for the LOGO!8 logic module ecosystem. For non-hazardous installations requiring the same form factor, see the standard LOGO!Power models in the 6EP333x series.
