PULS DIMENSION PISA11.402 4-Channel Electronic Fuse Module 24V DC, 4x2A

In industrial control cabinets, a single overloaded circuit can shut down an entire production line. The PULS DIMENSION PISA11.402 prevents this by electronically protecting four separate 24V DC circuits, each adjustable from 0.5 A to 2 A, so a fault on one channel does not affect the others.

Key specifications

• Input voltage: 18 - 32 VDC (nominal 24 VDC)
• Output channels: 4, each with adjustable current limit 0.5 A to 2 A
• Maximum total output current: 8 A
• Protection: electronic selective fusing per channel
• Status indication: green/red LED per channel plus collective alarm LED
• Alarm output: potential-free contact
• Connection: screw terminals
• Mounting: DIN rail
• Operating temperature: -25°C to +70°C
• Efficiency: >99%
• Voltage drop per channel: < 50 mV
• Short-circuit current (input): >100 A
• Reverse polarity protection: yes (input)
• Housing material: plastic
• Degree of protection: IP20

Why choose it

Selective fusing means only the faulty circuit is disconnected, while the other three continue to operate. This minimizes downtime and simplifies troubleshooting in distributed power systems.

Ideal use cases

• Protecting sensors, actuators, and controllers in machine building
• Distributing 24V DC power in control panels
• Replacing multiple single-channel circuit breakers to save space

Good to know

The module is part of the PULS DIMENSION series, designed for DIN rail mounting. It includes screw terminals for secure wiring and LED indicators for quick status checks.
