PULS DIMENSION PISA11.404 4-kanavainen turvamoduuli 24 V/DC 4 x 4 A

In industrial control cabinets, the PULS DIMENSION PISA11.404 protects four 24 V DC load circuits individually. Each channel can be set to 1 A, 2 A, 3 A, or 4 A, and the module trips electronically within microseconds on overload or short circuit. This keeps unaffected loads running and makes fault finding fast.

Key specifications

• Efficiency: > 99 %
• Connection: screw terminals
• Status indication: LED per channel (green/red)
• Protection: overload, short-circuit
• Degree of protection: IP20
• Input current (max): 40 A
• Output voltage: same as input voltage
• MTBF: > 1,000,000 h

Why choose it

The PISA11.404 replaces four separate circuit breakers with one compact module. Its selectable current limits adapt to different loads, and the fast electronic trip prevents nuisance tripping from inrush currents. The LED per channel shows at a glance which circuit has tripped.

Ideal use cases

• Protecting sensors, actuators, and control circuits in machines
• Distributing 24 V DC power to multiple loads from a single supply
• Reducing downtime by isolating faults to one channel

Good to know

The module is designed for DIN rail mounting and connects with screw terminals. It operates at an efficiency above 99 %, so it adds almost no heat to the cabinet.
