PULS DIMENSION PISA11.CLASS2 modulo di protezione elettronico a 4 canali 24 VDC, 4 x 3,7 A

The PULS DIMENSION PISA11.CLASS2 stands out with its four independently protected channels, each delivering up to 3.7 A from a 24 VDC supply. Unlike single-channel fuses, this module lets you distribute and safeguard multiple loads from one compact DIN-rail unit, with electronic trip response in under 100 µs.

Highlights

• 4 channels, each rated 3.7 A (total 14.8 A)
• Input voltage range 18–32 VDC, nominal 24 VDC
• Electronic fuse breaking with overload and short-circuit protection
• Ultra-fast short-circuit response: < 100 µs
• LED status per channel (green/red) plus input voltage LED
• Efficiency > 99%, voltage drop < 0.2 V
• DIN-rail mounting with screw terminals

In daily use

Each output is individually monitored and protected. If one channel trips, the others keep running, which reduces downtime in control cabinets. The LEDs give immediate visual feedback, and the module resets by removing the fault—no fuse replacement needed.
