KinCony F16 – 16-Channel ESP32-S3 Relay Controller (DIN-Rail)
Overview
The KinCony F16 is a DIN-rail mounted 16-channel ESP32-S3 relay controller designed for smart home, industrial control, and automation projects.
It includes removable OMRON relays, Ethernet, RS485, 1-Wire, analog inputs, RF433 receiver, SD card support, and a DS3231 RTC for time-critical automation.
Compatible with ESPHome, Home Assistant, Tasmota, Arduino, ESP-IDF, and MicroPython.
Key Features
• ESP32-S3-WROOM-1U (N16R8) processor module
• 16 removable OMRON relay channels (COM/NO, up to 250VAC/16A)
• Ethernet (LAN 100 Mbps), Wi-Fi, Bluetooth
• RS485 interface for Modbus/serial automation
• 16 dry-contact isolated inputs (500 m cable supported)
• 4 × 1-Wire GPIO (with built-in pull-ups)
• 4 analog inputs → 2 × 0–5V (A1/A2), 2 × 4–20mA (A3/A4)
• 2 free GPIOs exposed directly from the ESP32-S3
• DS3231 high-precision RTC with battery holder
• RF433MHz receiver socket
• SD card slot (SPI bus)
• LCD display showing IP address and Tuya connection state
• Manual relay control buttons (work even if firmware fails)
• DIN-rail mountable enclosure
