Industrial Automation 8-Layer Stackable HAT for Raspberry Pi

Industrial automation hardware for Raspberry Pi with modular I/O, standard communication interfaces, and support for widely used control and monitoring systems. The Industrial Automation HAT combines digital inputs, voltage and current analog I/O, MOSFET outputs, RS485/MODBUS, and 1-Wire interfaces in a compact, stackable platform for control, monitoring, and data acquisition.

• Digital, voltage, and current I/O on one board
• Native RS485 / MODBUS and 1-Wire interfaces
• Four MOSFET outputs for direct load control
• Up to 8 cards of each type can be stacked and mixed with other Sequent HATs for virtually unlimited I/O expansion
• Designed for control, monitoring, and data acquisition systems
• CE Certified to comply with EU regulatory requirements

Works with Open Automation Software

Compatible with widely used tools for control, monitoring, and system integration.

Description

The Industrial Automation HAT provides everything needed to build sophisticated industrial control, monitoring, and data acquisition systems with Raspberry Pi.

4–20 mA Inputs
Four optically isolated 4-20mA inputs read sensors from 2-wire, 3-wire, or 4-wire transmitters.
 
4–20 mA Outputs
Four 4-20mA outputs control actuators with 14-bit resolution and automatic load interruption detection.
 
0–10 V Analog Inputs
Four 16-bit 0-10V or ±10V analog inputs read high-precision voltage signals. The input range is software-selectable per channel — no jumpers or DIP switches required.
 
0–10 V Analog Outputs
Four 14-bit PWM 0-10V outputs control proportional actuators and drives.
 
MOSFET Outputs
Four open-drain MOSFET outputs switch DC loads up to 4A at 24V for direct control of solenoid valves, relays, and motors.
 
Digital Inputs & LED Outputs
Four optically isolated digital inputs accept signals from 0 to 24V. Four programmable LED outputs display the state of any digital or analog channel.
 
Real-Time Clock
The Real-Time Clock with CR2032 battery backup keeps accurate time through power failures, making the card ideal for data logging and time-stamped event recording.
 
Hardware Watchdog
The hardware watchdog automatically power-cycles the Raspberry Pi if the software becomes unresponsive, ensuring continuous operation in unattended deployments.
 
Protection
TVS diodes on all inputs protect against ESD and transient spikes. An onboard resettable fuse protects against accidental shorts.
