Getting started with the X-NUCLEO-OUT17A1 industrial digital output expansion
Introduction
The X-NUCLEO-OUT17A1 is an industrial digital output expansion board for
environment for the evaluation of the driving and diagnostic capabilities of the
state relay in a digital output module connected to 1.0 A industrial loads.
The X-NUCLEO-OUT17A1 interfaces with the microcontroller on the
®
Arduino UNO R3 connectors.
The user can select which driving mode controls the IPS8200HQ-1: parallel (SEL2 = L by JP21 = open) or SPI (SEL2 = H by
JP21 = closed).
In the case of SPI selection, the user can select the communication protocol between 8 bits (SEL1 = L by JP22 = open) or 16
bits (SEL1 = H by JP22 = closed).
The V supply pin of the IPS8200HQ-1

The on-board digital isolators
application sides: logic and process sides.
The logic side is the application side of the MCU and it is supplied by the VISO_L rail (3.3 or 5.0 V). VISO_L can be supplied by
an external power supply connected to CN13 or, alternatively by the pin 4 (SW1 = close 1-2) or pin 5 (SW1 = close 2-3) of CN6.
The process side is the application side of the industrial loads and it is supplied by the VCC and VISO_P rails. The VISO_P (3.3
or 5.0 V) is usually supplied by the VREG rail (JP31 = closed) that can be generated by the step-down embedded in the
IPS8200HQ-1 (SW17 = close 1-2, JP20 = closed, JP15 = closed and JP28 = close 2-4 (VREG = 3.3 V) or JP28 = 1-3 (VREG =
5.0 V)).
Alternatively, VREG can be provided by an external power supply connected to CN14 (SW17 = close 2-3, JP20 = open, JP15 =
open).
In parallel driving mode (active with the default jumper and switch settings) the application board can work even without any
Nucleo board: in this case, the user must provide the process side voltage (usually 24 V) by the CN1 and the VISO_L (usually
3.3 V) by the CN13. The IN

The IN pins can be driven low/high swinging between 0V and VISO_L. The activation of each OUTX (OUT1... OUT8) can be

monitored by the green LEDs DOX (DO1... DO8).
The activation of the three diagnostic pins (TWARN, PGOOD, FAULT) can be visualized on the correspondent red LEDs (D11,
D12, D13, respectively) or monitored by an oscilloscope on CN8[5], CN5[9], CN5[10].
The SPI driving mode can be set by changing the default configuration (JP21 = close; SW4, SW5, SW6, SW7, SW9, SW10,
SW11, SW12, SW13, SW14, SW15 and SW20 = close 2-3, SW18 = close 1-2). The SPI-8bits is the default mode (JP22 =
open), while the SPI-16bits mode can be activated by JP22 = close.
In SPI driving mode it is also possible to activate the MCU freeze detection feature by setting SW3 = close 2-3.
The expansion board can be connected to either a
the companion firmware X-CUBE-IPS
SEL2_L and SEL1 from CN8[1] and CN8[6]. The activation of the MCU freeze feature is detected by WDEN(in) on CN9[4].
It is also possible to evaluate a system composed of a
driving mode allows the daisy-chaining communication with another
connectors: the two stacked boards must be configured with SW6, SW18 = close 2-3 on one board, and SW6, SW18 = close
1-2 on the other board.
