WIN-PIHAT-16DI 16-Ch Digital Input HAT for Raspberry Pi 4/CM4

The WIN-PIHAT-16DI is engineered for direct compatibility with the Raspberry Pi 4 and Compute Module 4 (CM4). It interfaces via the standard 40-pin GPIO header, providing a robust solution for industrial expansion and integration into various embedded applications.

This HAT supports standard 3.3V–12V DC input signals, with high-voltage tolerance up to 80V DC (at a maximum of 50mA). This broad range makes it suitable for interfacing with diverse industrial sensors, relays, and field devices found in demanding automation environments.

Opto-isolation provides electrical separation between the industrial input signals and the Raspberry Pi's GPIO. This protects the sensitive Raspberry Pi from electrical noise, voltage spikes, and ground loops common in harsh industrial environments, ensuring reliable operation and longevity of the core system.

The WIN-PIHAT-16DI features a fast response time, typically 2 milliseconds, with a maximum of 6 milliseconds. This ensures near real-time acquisition of digital signals, which is critical for responsive industrial monitoring, control applications, and time-sensitive event detection within automation systems.

The WIN-PIHAT-16DI requires an external industrial power supply providing either 12V or 24V DC. This dedicated power input ensures stable and reliable operation, separate from the Raspberry Pi's power, which is crucial for maintaining signal integrity and system resilience in industrial settings.
