UNIVERSAL (Inputs) |
+15 V |
15 VDC Power Source for active (3-wire) input devices connected to the Universal INn terminals. Provides 100 mA total current |
Same as (Universal) IN n Note: Use 3-wire cable for devices that source power from the +15V
terminal.
|
|
IN n |
Analog Input - Voltage Mode (0–10 VDC) 10 VDC maximum input voltage Internal 75kΩ pull-down |
See Guideline A in Cable and wire length guidelines. |
|
|
Analog Input - Current Mode (4–20 mA) Internal 100 Ω load impedance. See Setting the Input Jumpers. Note: A current loop jumper must be in the Enabled position to maintain a
closed 4-20 mA current loop. See UI current loop jumpers.

|
ANALOG (Outputs) |
OUT n |
Analog Output - Voltage Mode (0–10 VDC) 10 VDC maximum output voltage 10 mA maximum output current Requires an external load of 1,000 Ω or more. Note: The Analog Output (AO) operates in the Voltage Mode when connected
to devices with impedances greater than 1,000 ohm. Devices that drop below 1,000 ohm
may not operate as intended for Voltage Mode applications.
|
See Guideline C in Cable and wire length guidelines. |
|
Analog Output - Current Mode (4–20 mA) Requires and external load between 0 and 300 ohm. Note: The Analog Output (AO) operates in the Current Mode when connected
to devices with impedances less than 300 Ω. Devices that exceed below 300 Ω may not
operate as intended for Current Mode applications.
|
|||
|
OCOM n |
Analog Output Signal Common for all Analog OUT terminals. Note: All Analog Output Common terminals (OCOMn)
share a common, which is isolated from all other commons. One common screw terminal
point is provided for every two output screw terminal points.
