Accuracy and linearity: ±1.5% of rated output current. 
Turns the output off with a LOW (0V to 0.5V) or short-
circuit. 
Possible logic selections: 
Turn the output on using a LOW (0V to 0.5V) or short-
circuit, turn the output off using a HIGH (4.5V to 5V) or 
open-circuit. 
Turn the output on using a HIGH (4.5V to 5V) or open-
circuit, turn the output off using a LOW (0V to 0.5V) or 
short-circuit. 
Clear alarms with a LOW (0V to 0.5V) or short-circuit.
