3.2.4 Binary Input
Use For external selection of Parameter set A or B.
• Logic 1 = Parameter set A (Relay control A)
• Logic 0 = Parameter set B (Relay control B)
Levels Logic 1 = V > +3.5V
Logic 0 = V < +1.5V
Reference Sensor supply 0V
Max voltage 36V
Input resistance R
min
= 10K
Ω
Circuit Internal pull up resistance to 5V
Shorting the binary input to the sensor 0V
creates logic 0.
