PULS PISA-M-4CL2 4-Channel Selective Current Limiter Module 20A 18-30VDC DIN Rail

Deliver up to 20 A across four independently protected channels with the PULS PISA-M-4CL2 selective current limiter module. Each channel offers adjustable current limiting from 0.5 A to 6 A, ensuring reliable operation of connected loads even under overload or short-circuit conditions.

Overview

The PISA-M-4CL2 is a DIN-rail mountable module designed to distribute a 24 VDC supply to four separate circuits while providing selective protection. It operates with an input voltage range of 18-30 VDC and passes through the input voltage to the outputs. The module features screw terminals for both input and output connections, and each channel has an LED status indicator for quick fault identification.

What stands out

• Four independently adjustable current-limited channels (0.5 A to 6 A each)
• Total output current up to 20 A with efficiency greater than 99%
• Comprehensive protection: overload, short-circuit, and reverse polarity on input
• Wide operating temperature range from -25°C to +70°C
• High reliability with MTBF exceeding 1,000,000 hours
• Compact DIN-rail housing with IP20 protection
