To use with a logic pwm signal (any logic voltage matching the mosfet) you also need a power rail of 5, 12 or 24Vdc that shares a common with the logic. Connect the power rail between the appropriate ...

The programmable logic controller is fitted with 32 Inputs offering : 16 x digital 4-30V, 8 x analog 0-10V, 4 x analog 0-5V, 4 x analog 4-20mA) and 20 Outputs (8 x relay 250V/5A, 2 x open ...

The circuit on the left can interface with any one of those, plus any 5V logic signal if a dc voltage of 5, 12 or 24V is also available. 16mA has been chosen for the led current to match the drive ...
