#DAISY-19 - 4 channels industrial range optoisolated output (0-48 Volt)

<div class="text-success lead">
Four isolated outputs MOSFET channels for DC loads such as DC motors,
Peltier cells, light bulbs, solenoids, resistive heaters, etc.
</div>

The board is equipped with four leds to check each output state. When a led is on its associated output is active (the MOSFET is conducting).

### Features

*  4 channels output stage driven by MOSFETs
*  Drain-source voltage max: 48 Volt
*  Continuous source current: 3.5 A
*  Isolation voltage: 2500 Vrms (max)

The daisy connectors where to plug this board are:

| Daisy Connector | 
|-----------|
| FOX D2    |
| FOX D5    |
| TERRA D11 |
| TERRA D12 | 

On the FOX Board G20 is requested a [Daisy-1](/DAISY-1) adapter.


## General Layout

The following picture shows Daisy-19 connectors and monitoring LEDs.

## Connecting to a Daisy-1

Up to 2 Daisy-19 boards can be connected to the same Daisy-1 connector by means of the Replicator connector J3. So full use of all I/O pins on a single Daisy-1 connector is made. This applies to Daisy-1 connectors: D2, D3, D5 provided all pins are set as GPIO.

Daisy-19 cascading feature is illustrated by the following picture :

## Using one board to drive loads in more than one way

Due to the "floating" optoisolated N channel MOSFETs, the Daisy-19 is able to handle different kinds of loads and drive configurations with single and dual power supply :

### Sink mode (aka NPN)

Up to 4 loads can be driven in this configuration.

### Source mode (aka PNP)

Up to 4 loads can be driven in this configuration.

### Half H bridge mode

Up to 2 loads can be driven in this configuration.

Make sure voltage between V+ an V- does not exceed 48V.

### Full H bridge mode

Just 1 load can be driven in this configuration.

Mixed modes are easily handled by Daisy-19 as shown in the following case list:

Case A :

*  Output 1 : Sink mode +24V
*  Output 2 : Source mode +5V
*  Output 3 : Source mode +12V
*  Output 4 : Sink mode +5V

Case B :

*  Output 1 : Sink mode +24V
*  Output 2: Source mode +5V
*  Outputs 3 & 4 : Half Bridge +/-12V

Case C :

*  Outputs 1 & 2 : Half Bridge +/-24V
*  Outputs 3 & 4 : Half Bridge +/-12V
