The KS032 PTC-8 is an 8-channel power distribution board with resettable PTC fuse protection and real-time fuse-status monitoring over a serial interface. Connect it between your PSU (up to 30VDC) and your loads — motors, solenoids, lamps, amplifiers — to protect each circuit independently and monitor which fuses have tripped.

A shift-register serial interface (5V or 3.3V selectable) lets an Arduino, STM32, or Raspberry Pi read the live state of all 8 fuses with a single SPI transaction. Daisy-chain multiple KS032 boards to monitor more than 8 circuits without adding MCU pins.

Supplied with:

• 8× 30V 5A PTC resettable fuses (UL listed, unsoldered — swap in your own rating if needed)
• XH-7 connector and terminals for the logic interface
• VH8 and VH9 connectors and terminals for power input and output

Features:

• 8 independently protected power channels
• Resettable PTC fuses — no fuse replacement after a trip
• Serial fuse-status readout — know which circuit tripped and when
• Daisy-chainable for unlimited channel count
• LED indicators for all 8 input and output voltages
• Up to 30VDC input
