 Using Transistors for Input Signals and a 0-V Common in Sinking Mode
with an External Power Supply
Set CN5 (shunt connector) on the control board to EXT as shown below for a sequence that uses an NPN tran-
sistor for an input signal (0-V common and sinking mode) and an external +24-V power supply.
