The tHAT2 module offers additional 4 outputs in the open collector standard, driven by PWM outputs, for controlling relays. The board also has an RS485 converter for Modbus bus support. There are also outputs OUT1-OUT4 and supply voltage, analog inputs INPA5 and INPA6, and 3.3 V voltage for powering sensors.
The IDC10 version of tHAT2 overlay has IDC10 connectors for connecting relay boards.
To control outputs 6-9 you have to enable Mode ON/OFF for pwm outputs like on image below.
