Siemens presents the 6SL3120-2TE21-8AC0, a versatile double-motor module in a compact booksize format. This unit measures 380 mm in height, 270 mm in width, and 100 mm in depth, equating to approximately 14.96 in x 10.63 in x 3.94 in. It delivers a nominal output current of 2 x 18.0 A. The power loss figures indicate typical and maximum losses of 0.28 kW and 0.35 kW, respectively.

This system operates with a DC voltage range from 510 V to 720 V and has a rated base load current of 2 x 15.3 A. Under specific conditions, peak current for S6 operation can reach up to 2 x 36.0 A, accommodating demanding applications. With a switching frequency of 4.00 kHz, it effectively supports a variety of tasks. Regarding cabling, maximum length limitations for motor cables are set to 70 m when shielded and 100 m when unshielded.

An integrated cooling mechanism, specifically air cooling, ensures consistent operation within a temperature range of 0°C to 40°C (32°F to 104°F). This module can function at altitudes as high as 1000 m without any loss of efficiency. Safety regulations are reliably met, as this model complies with SL 2 (IEC 61508), PL d (EN ISO 13849-1), and Category 3 (EN ISO 13849-1) standards.

The unit's protection rating is IP20 for standard safety and UL open type, facilitating usage in various operational environments. It also features a substantial link capacitance of 705 μF, further enhancing its performance capabilities in electrical applications.
