Inputs
DP570 Series Displays support the following pin types:
•
Digital or Analog (DIN/AIN)
•
Digital, Analog, or 4–20 mA (DIN/AIN/4–20 mA)
•
Multifunction (DIN/AIN/FreqIN, Rheo, 4–20 mA)
DP570 Series Displays have input pins that support multiple functions. Pins that support multiple input
types are user-configurable using PLUS+1
®
GUIDE software.
