Terminal P24AUX supplies digital inputs DI1 and DI2. No external 24 V
supply may be connected to this terminal.The current output at terminal
P24AUX, i.e. the total outputs of all option boards, must not exceed
150 mA.
The board EB2 is designed as a PELV circuit (Protective Extra Low
Voltage). The ground of board EB2 is connected internally to earth.
