The ESP8266 8x8 module is WiFi, designed for DIN mounting, compatible with ESP Easy firmware, with integration for HOME ASSISTANT.
Communication to the Home assistant is via the MQTT protocol.
Supports 8 relay outputs SPDT, + 8 inputs 220V AC - yes / no 220V AC.
These inputs and outputs are visible as GPIO 1-16 on MCP23017
The module is powered by 12 V DC, 400 mA
The module is available with uploaded firmware for ESP8266, free, which is not subject to commercial relationships

The ESP8266_8 relay module is WiFi, designed for DIN mounting, compatible with the ESP Easy firmware, with integration for HOME ASSISTANT. The communication to the Home assistant is through the MQTT
protocol. Supports 5 relay outputs SPDT, + 4 inputs dry contact type, active level is a connection to ground.
These inputs and outputs are visible as GPIO 1-16 of the MCP23017.
The dry contact inputs have pull-up resistors 5.1k and a series LED to 3.3V.
GPIO13 - 1wire terminal has a pull-up resistor 4.7k to 3.3V.

MODBUS-compliant board supporting 2 incremental rotary controllers and 4 additional logic inputs.
See description for details.

TAIO-15-1 module can provide any PLC system with one analog input and one analog output, both in the range of 0-10V and both isolated from the communication bus as well as from the input power supply.

TTCS is a fully-featured temperature control system. Among those features are:

• Constant real-time temperature monitoring
• Visual and audio alarms, for both high and low temperatures, configurable per silo
• Full temperature history
• Built on cutting-edge technology, the user interface is based entirely on HTML5 and works in any modern browser, including smartphones and tablets and accesible through LAN / internet
• Easy to extend due to its scalable design
• Integration with TPLC
