+15 V
15 VDC Power Source for active (3-wire) input devices
connected to the Universal UI-n terminals.
Provides 100 mA total current
Same as (Universal) UI-n
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 10k ohm Pull-down
See Guideline A in Table 3
Analog Input - Current Mode (4–20 mA)
Internal 100 ohm load impedance
Note: Current loop jumpers must be in the Enabled
position to maintain a closed 4-20 mA current loop. See
Setting the UI current loop jumpers.
See Guideline B in Table 3.
Analog Input - Resistive Mode (0–600k ohm)
Internal 12 V. 15k ohm pull up
Qualified Sensors: 0-2k ohm potentiometer, RTD (1k Nickel
[Johnson Controls
®
sensor], 1k Platinum, and A99B Silicon
Temperature Sensor) Negative Temperature Coefficient (NTC)
Sensor
See Guideline A in Table 3.
UI-n
Binary Input - Dry Contact Maintained Mode
1 second minimum pulse width
Internal 12 V. 15k ohm pull up
See Guideline A in Table 3.
UNIVERSAL
(Inputs)
UI-Cn
Universal Input Common for all Universal Input terminals
Note: All Universal UI-Cn terminals share a common,
which is isolated from all other commons.
Same as (Universal) UI-n
Binary Input - Dry Contact Maintained Mode
0.01 second minimum pulse width
Internal 18 V. 3k ohm pull up
BI-n
Binary Input - Pulse Counter/Accumulator Mode
0.01 second minimum pulse width
(50 Hz at 50% duty cycle)
Internal 18 V. 3k ohm pull up
BINARY
(Inputs)
BI-Cn
Binary Input Common for all Binary Input terminals
Note: All Binary BI-Cn terminals share a common,
which is isolated from all other commons, except the
Configurable Output (CO) common (CO-Cn) when the
CO is defined as an Analog Output.
See Guideline A in Table 3.
