ST X-NUCLEO-OUT10A1 User manual

Introduction

The X-NUCLEO-OUT10A1 industrial digital output expansion board for STM32 Nucleo provides an affordable and easy-to-use

solution for the development of 0.5 A (typ.) digital output modules, letting you easily evaluate the IPS161HF driving and

diagnostic capabilities with industrial loads.

The X-NUCLEO-OUT10A1 interfaces with the microcontroller on the STM32 Nucleo via 3 kV optocouplers driven by GPIO pins

and Arduino™ UNO R3 (default configuration) and ST morpho (optional, not mounted) connectors.

The expansion board should be connected to either a NUCLEO-F401RE or NUCLEO-G431RB development board, and can be

stacked with another X-NUCLEO-OUT10A1 or an X-NUCLEO-OUT08A1 .

Two X-NUCLEO-OUT10A1 expansion boards allows you to evaluate a dual channel digital output module with 0.5 A (typ.)

capability each, or a 0.5 A (typ.) single channel safety digital output module. In the second scenario, the first shield output is

connected to the supply of the second one. Dedicated on-board hardware can be enabled or disabled to activate fast discharge

of high capacitive loads, output voltage sensing and additional surge pulse output line protection.

1.1 Overview

The X-NUCLEO-OUT10A1 industrial digital output expansion board, embedding the IPS161HF intelligent power

switch (IPS), is designed to meet the application requirement in terms of galvanic isolation between user interface

(or logic side) and power interface (or process side).

This requirement is satisfied by an optical isolation implemented through two couples of optocouplers:

1. The first couple includes:

a. ISO1: for signal forwarding to the device

and

b. ISO2: for diagnostic signal (DIAG pin) feedback

2. The second couple incudes:

a. ISO3: for the additional output voltage feedback signal

and

b. ISO4: for the additional circuitry driving Q1 to allow fast discharge of the output rail

The main features of the X-NUCLEO-OUT10A1 expansion board are:

• Based on IPS161HF single high-side switch with the following main features:

– Operating range up to 60 V/0.7 A

– Low power dissipation (RON(MAX) = 120 mΩ)

– Fast decay for inductive loads

– Open load detection and diagnostics

– Overload and overheating protections with thermal shut-down and cut-off

– PowerSSO-12L package

• Application board operating range: 12 - 33 V, 0 to 0.7 A

• Extended voltage operating range (J1 open) up to 60 V

• Green LED for output ON/OFF status

• Red LED for diagnostics (open load, cut-off and overheating)

• 3 kV galvanic isolation

• Supply rail reverse polarity protection

• Ready for Safety Digital Output Architecture

• EMC compliance according to IEC61000-4-2, IEC61000-4-3, IEC61000-4-5

• Wide application development potential in STM32 Nucleo development environment

• Equipped with Arduino™ UNO R3 connectors

• CE certified

• RoHS and China RoHS compliant

1.1.1 Digital section

The digital section is associated with the STM32 interface and digital supply voltage to and from the X-NUCLEO-

OUT10A1 expansion board.

The digital and power sections are isolated by 3.3 mm creepage. Communication between the two sections is

guaranteed by ISO1, ISO2, ISO3 and ISO4 optocouplers.

UM2716

Getting started

UM2716 - Rev 1 page 2/16

Figure 2. X-NUCLEO-OUT10A1 expansion board: digital interface components

The four Arduino® UNO R3 connectors:

• allow expansion board communication with the STM32 Nucleo development board accessing STM32

peripheral and GPIO resources;

• provide digital supply voltage between the STM32 Nucleo development board and the X-NUCLEO-

OUT10A1 expansion board, in either direction.

Normally, the STM32 Nucleo development board supplies the expansion board by 3v3 or 5v0 (JP5 pins 1-2

closed) generated by the USB. You can select the preferred voltage on the expansion board via SW2 (3v3 by

closing pins 1-2; 5v0 by closing pins 2-3).

Alternatively, it is possible to supply the STM32 Nucleo development board by the expansion board. In this case,

an external supply voltage (7-12 V) should be connected to CN2 connector (not mounted by default) on the

expansion board and the ground loop should be closed by mounting D2 (that enables reverse polarity protection)

or by closing J3 (without reverse polarity).

To supply the VIN voltage rail is necessary to:

• close jumper JP5 between pins 2 and 3 and open jumper JP1 on the NUCLEO-F401RE

• open jumper JP5 between pins 1 and 2 and close jumper JP5 between pins 3 and 4 on the NUCLEO-

G431RB

1.1.2 Power section

The power section involves the power supply voltage (CN1, pin 1 VCC, pin 2 GND), load connection (between

CN1 pin 3 and CN1 pin 2) and electromagnetic compatibility (EMC) protection (U2).

UM2716

Overview

UM2716 - Rev 1 page 3/16

Figure 3. X-NUCLEO-OUT10A1 expansion board: power stage components

For EMC:

• the transient voltage suppressor (U2), enabled by closing J1, is placed between VCC and GND tracks to

protect the IPS161HF against surge discharge on the supply rail path up to ±1 kV/2Ω coupling;

• in common mode surge testing, two single-layer capacitors (C1 and C2 - not included) must be soledered at

the predisposed locations;

• the IPS161HF output stages do not require additional EMC protections with respect to IEC61000-4-2 (± 10

kV contact, ±16 kV air), IEC61000-4-4 (± 4 kV), IEC61000-4-5 (± 3.5 kV) standards.

1.2 Hardware requirements

The X-NUCLEO-OUT10A1 expansion board is designed to be used with the NUCLEO-F401RE or NUCLEO-

G431RB STM32 Nucleo development boards.

To function correctly, the X-NUCLEO-OUT10A1 must be plugged onto the matching Arduino® UNO R3 connector

pins on the STM32 Nucleo board as shown below.

1.3 System requirements

To use the STM32 Nucleo development boards with the X-NUCLEO-OUT10A1 expansion board, you need:

• a Windows PC/laptop (Windows 7 or above)

• a type A to mini-B USB cable to connect the STM32 Nucleo board to the PC when using a NUCLEO-

F401RE development board

• a type A to micro-B USB cable to connect the STM32 Nucleo board to the PC when using a NUCLEO-

G431RB development board

• the X-CUBE-OUT8 firmware and software package installed on your PC/laptop

1.4 Board setup

Step 1. Connect the X-NUCLEO-OUT10A1 to the NUCLEO-F401RE or NUCLEO-G431RB development board

through the Arduino connectors.

Step 2. Connect the X-NUCLEO-OUT10A1 power section (see Section 1.1.2 Power section).

Step 3. Connect the load between CN1 pins 2 and 3.

Step 4. Connect the mini-USB (for NUCLEO-F401RE) or micro-USB (for NUCLEO-G431RB) cable between

your PC and the STM32 Nucleo board.

Step 5. Download the selected firmware (STSW-OUT8F4 for NUCLEO-F401RE or STSW-OUT8G4 for

NUCLEO-G431RB) onto the microcontroller.

Step 6. Provide the digital supply voltage (see Section 1.1.1 Digital section).

Step 7. Reset the example sequence by pushing the black button on the STM32 Nucleo board.

Step 8. Push the blue button on STM32 Nucleo board to choose among the examples provided in the default

firmware package.

Note: When using two boards stacked (e.g. dual channel digital output or single channel safety digital output

application), you have to move some signal enabler resistors from DEFAULT to ALTERNATE position. You can

refer to the expansion board schematic and/or to the table below (where board 0 mounts all the resistors in their

DEFAULT position).
