ST X-NUCLEO-OUT01A2 User manual

Introduction
The X-NUCLEO-OUT01A2 is an industrial digital output expansion board for STM32 Nucleo. It provides a powerful and flexible
environment for the evaluation of the driving and diagnostic capabilities of the ISO8200BQ octal high-side smart power solid
state relay, with embedded galvanic isolation, in a digital output module connected to 0.7 A industrial loads.
The X-NUCLEO-OUT01A2 directly interfaces with the microcontroller on the STM32 Nucleo driven by GPIO pins and Arduino®
R3 connectors.
The galvanic isolation between the microcontroller and the process stage is guaranteed by the ISO8200BQ.
The expansion board can be connected to either a NUCLEO-F401RE or a NUCLEO-G431RB development board.
It is also possible to evaluate a system composed of a X-NUCLEO-OUT01A2 stacked on other expansion boards.
The board can be configured as the former X-NUCLEO-OUT01A1 by a set of jumpers (open: J13, J14, J15, J16, J17) and
switches (close 1-2: SW1, SW28, SW29, SW30, SW31, SW32, SW33, SW35, SW37). In this case, the driving firmware can be
only the X-CUBE-OUT1 and the board can be connected to the X-NUCLEO-PLC01A1 to form a powerful industrial PLC with 8
inputs and 16 outputs. Also, wireless communication capabilities can be added with the X-NUCLEO-IDW01M1, which
establishes communication on a smart device to manage the PLC remotely. A dedicated ST-PLC app is available for Android™
and iOS™ systems for this purpose.

1.1 Overview
The X-NUCLEO-OUT01A2 embeds the ISO8200BQ intelligent power switch (IPS), which features galvanic
isolation, overcurrent and overtemperature protection for safe output loads control.
The board is designed to meet the application requirements for the galvanic isolation between the user and power
interfaces.
The galvanic isolation embedded by the ISO8200BQ satisfies this requirement, avoiding the necessity of external
optocouplers, with a consequent cost saving and a reduced application size.
The expansion board features:

1.3 Digital section
The digital section is associated with the STM32 interface and the digital supply voltage to and from the X-
NUCLEO-OUT01A2 expansion board.
Figure 2. X-NUCLEO-OUT01A2 expansion board: digital interface section
The dotted green line indicates the whole digital interface section. The pink rectangles identify the Arduino® UNO
R3 connectors.
The four Arduino® UNO R3 connectors:
• allow the expansion board to communicate with the STM32 Nucleo development microcontroller board
accessing the STM32 peripheral and GPIO resources;
• provide the digital supply voltage between the STM32 Nucleo development board and the X-NUCLEO-
OUT01A2 expansion board, in either direction.
Usually, the STM32 Nucleo development board supplies the expansion board by a 3.3 V or 5.0 V generated by
the USB.
Alternatively, it is possible to supply the STM32 Nucleo development board from the expansion board. In this
case, an external supply voltage (7-12 V) should be connected to the CN11 connector (not mounted by default)
on the expansion board and the ground loop should be closed by mounting D2 (enabling the reverse polarity
protection) or by closing J5 (without reverse polarity). In this scenario, the logic side of the ISO8200BQ can be
supplied by the 3.3 V supply rail generated by the expansion board: in this case, on the X-NUCLEO-OUT01A2, J4
must be closed between pins 5 and 6.
To supply the VIN voltage rail, it is necessary to:
• close the JP5 jumper between pins 2 and 3 and open the JP1 jumper on the NUCLEO-F401RE;
• open the JP5 jumper between pins 1 and 2 and close the JP5 jumper between pins 3 and 4 on the
NUCLEO-G431RB.
The pin 3 of the connector CN11 can be used to supply the logic side of the ISO8200BQ independently by the
expansion board. In this case, on the X-NUCLEO-OUT01A2, the pins 1 and 2 of J4 must be closed (pins 5-6
open).

1.4 Power section
The power section involves the power supply voltage (CN1, pin 1 for VCC, pin 2 for GND), the load connection
(eight loads can be connected between each pin of CN2, CN3, CN4, and CN12 and pin 2 of CN1), EMC
protections (U2), and supply reverse polarity protection (D1).

1. ISO8200BQ
2. Output and power supply connector
3. Output channels - green LEDs
4. Status (overtemperature) red LED
5. Output Enable yellow LED
For EMC:
• the SM15T39CA transient voltage suppressor (U2), enabled by closing J9, is placed between VCC and
GND tracks to protect the ISO8200BQ against surge discharge on the supply rail path up to ±1 kV/2 Ω
coupling;
• in the common mode surge testing, two single-layer capacitors (C11 and C12 - not included) must be
soldered at the predisposed locations;
• the ISO8200BQ output stages do not require additional EMC protections with respect to the IEC61000-4-2,
IEC61000-4-3, IEC61000-4-4, IEC61000-4-5, IEC61000-4-8 standards.
The EMC performance of the X-NUCLEO-OUT01A2 is detailed below:
• for emission (when the DC input port of the board is powered by an AC-DC, DC-DC or battery with a cable
that does not exceed a three-meter length), compliance with standards:
– EN IEC 61000-6-3:2021
– EN 55032:2015 +A1:2020
• for immunity, compliance with standards:
– EN IEC 61000-6-1:2019
– EN 55035:2017 +A11:2020

1.5 Hardware requirements
The X-NUCLEO-OUT01A2 expansion board is designed to be used with the NUCLEO-F401RE or NUCLEO-
G431RB STM32 Nucleo development boards.
To function correctly, the X-NUCLEO-OUT01A2 must be plugged onto the matching Arduino® UNO R3 connector
pins on the STM32 Nucleo board as shown below.
Figure 4. X-NUCLEO-OUT01A2 and STM32 Nucleo stack
1.6 System requirements

• 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-

1.7 Board setup
If the board is configured as X-NUCLEO-OUT01A1, refer to UM2209 and X-CUBE-OUT1 as the control firmware.
When the board is configured as X-NUCLEO-OUT01A2, refer to the following steps:
Step 1. Connect the mini-USB or micro-USB cable to your PC to use the X-NUCLEO-OUT01A2 with NUCLEO-
F401RE or NUCLEO-G431RB development board
Step 2. Download the firmware (.bin) provided with the X-CUBE-IPS software package as detailed in Table 4.
The X-NUCLEO-OUT01A2 must be configured coherently to the selected control mode for ISO8200BQ
through SW37 and SW36. These switches define the level of ISO_DRV signal: according to the level of
this signal (high or low), the firmware will properly manage respectively the synchronous or the direct
control mode.
