W1209 - Temperature Controlled Relay Module - Thermostat Module - 50 to 120 ℃

This thermostat module designed around STM8S003F3P6 microcontroller is ideal for temperature controller device switching control. Can work on temperature ranges of 50 to 120 ℃. 3 buttons are given on board to set the desired temperature. Relay can switch AC voltage of up to 120VAC and 20A current. This relay is not suitable to switch 220V AC appliances, an external appropriate relay module could be used along with this module for switching higher voltage or current rating devices.
