The NOVABASE NB20446 circuit board is based on the ModbusRTU protocol and allows a really precise temperature measurement, thanks to four PT100/4-20mA sensors, and manages up until 20 triac outputs.

Default 24V power supply, it’s also possible to require the 220V AC power supply.

The circuit board can be set up through RS232 or RS485 serial port (through an onboard switch) and can be expanded through another RS485 serial port (not set up by default).

Easily programmable through jumpers to modify PT100 inputs in 4 different analog 4/20mA inputs.
