UNCTION
The device is equipped with a remote ON/OFF function to turn the output ON or OFF.
Two logics are possible. With the positive logic (standard version), the output switches OFF as soon as pin 2
(-Vin) and pin 6 (RC) are linked or a voltage of less than 1.2V is present.
The optionally available negative logic (option –N) is exactly the vice versa. Here the output switches ON as
soon as pin 2 (-Vin) and pin 6 (RC) are linked or a voltage of less than 1.2V is present.
The RC-input is a sink input, which requires a maximal current of 1mA (typically 0.4mA) to be activated. The
maximal allowed voltage (open circuit voltage) for this pin is 160Vdc.
