STMicroelectronics X-NUCLEO-OUT06A1

Overview

X-NUCLEO-OUT06A1 from STMicroelectronics is an industrial digital output expansion board for STM32 Nucleo development platforms, built around the IPS1025H-32 single high-side smart power switch. It delivers up to 5.7 A load current at 8–33 V (extendable to 60 V), features 5 kV galvanic isolation via optocouplers, and provides real-time diagnostics via red LEDs for overload/overtemperature events.

For engineers reviewing the X-NUCLEO-OUT06A1 datasheet, X-NUCLEO-OUT06A1 pinout, X-NUCLEO-OUT06A1 application, or X-NUCLEO-OUT06A1 equivalent, this board enables rapid evaluation of high-side switching performance, fault response timing, isolation integrity, and multi-board stacking scalability in PLC I/O module designs.

Technical Context

The board interfaces with STM32 Nucleo microcontrollers via GPIO-driven TLP383 optocouplers, providing 5 kV input-to-output galvanic isolation. Control signals are level-shifted and filtered, while diagnostics (FLT1/FLT2) feed back overtemperature and overload states directly to MCU pins.

It supports dual supply configurations: default 5 V logic from Nucleo (via Arduino R3 headers) and isolated 8–60 V load power (J3 open/closed). Reverse polarity protection on VIN and EMC compliance per IEC61000-4-x standards ensure robust operation in industrial noise environments.

FAQ

What microcontrollers is the X-NUCLEO-OUT06A1 compatible with?

The board is natively compatible with STM32 Nucleo development boards including NUCLEO-F401RE and NUCLEO-G431RB. It connects via Arduino UNO R3 and ST morpho headers, enabling direct GPIO control and diagnostic feedback without additional level-shifting circuitry.

Does the board support multiple units stacked for multi-channel operation?

Yes - up to four X-NUCLEO-OUT06A1 boards can be physically and electrically stacked. Each retains independent control and fault reporting via dedicated optocoupled inputs and FLT outputs, allowing evaluation of scalable quad-channel digital output architectures.

How is overtemperature and overload protection implemented?

Protection is handled by the onboard IPS1025H-32 high-side switch, which integrates internal thermal shutdown and current-limit sensing. Fault conditions assert open-drain FLT1 (overtemperature) and FLT2 (overload) signals, each with defined voltage thresholds and response times documented in the IPS1025H-32 datasheet.

Is external power required for the load side, and what voltage range is supported?

Yes - the load side requires an isolated DC supply connected to the VIN terminal. The board operates at 8–33 V by default; opening jumper J3 extends the maximum input to 60 V, aligning with common industrial 24 V and 48 V DC bus standards.
