Note:
Use 3-wire cable for
devices that source power
from the +15V terminal.
Analog Input - Voltage Mode (0–10 VDC)
10 VDC maximum input voltage
Internal 75k ohm Pull-down
See Guideline
A
Analog Input - Current Mode (4–20 mA)
Internal 100 ohm load impedance
Note:
Current loop jumpers are fail-safe to maintain a
closed 4 to 20 mA current loop, even when the power to
the controller is interrupted or off. See
