Smartisant 8-Channel Fused Input Board IP1

The Smartisant 8-Channel Input Board IP1 is one of our smart home building blocks and makes it simple to power and connect a wide range of 12V dc sensors to a smart home. The board uses opto-couplers to separate the 12V sensors from the 5V logic functions.

The PCB exposes 8 channels via a 4-way Molex connector and connects to our other boards via a 10-way shrouded header connector. A 12V power source is connected to the board to deliver 12V power to each channel via a 20mm fuse, to minimise the impact one sensor failure might have on the other channels.

Note:  This board is basically the same as the Smartisant 8-Channel 12V Input Board IP2 but with protection fuses on each channel.
Note: 

There are two purchase options:

  1. The PCB only.
  2. The PCB with a kit of parts to be soldered to the board. This includes a 10-way shrouded header connector, eight 4-way Molex connector, two quad opto-isolators, eight 2.4KΩ resistors, eight 3.9KΩ resistors, eight 20mm fuse holders and eight 1A 20mm fuses.
