KinCony KC868-E16S - Relay Controller (Din Relay)
The KinCony KC868-E16S is a 16-channel ESP32 relay controller designed for smart home, industrial automation, and control cabinet installations. Built around the ESP-WROOM-32, it combines high-current relay outputs with isolated digital inputs, analog sensing, and multiple communication interfaces in a DIN-rail enclosure.
It features 16 relay outputs rated at 250VAC/16A, 16 opto-isolated dry-contact inputs, 0–5V and 4–20mA analog inputs, Ethernet, RS485, Wi-Fi, Bluetooth, and 433 MHz RF support. The controller is compatible with ESPHome, Tasmota, KCS firmware, Arduino, and ESP-IDF, allowing flexible integration into Home Assistant or custom automation systems.
