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.

See Guideline B in Cable and wire length guidelines.

Analog Input - Resistive Mode (60–600kΩ)

Internal 12 V. 15k Ω pull-up

Qualified Sensors: 0–2kΩ potentiometer, RTD (1k Nickel [Johnson Controls sensor], 1k Platinum, and A99B Silicon Temperature Sensor) Negative Temperature Coefficient (NTC) Sensor

See Guideline A in Cable and wire length guidelines.

Binary Input - Dry Contact Maintained Mode

1 second minimum pulse width

Internal 12 V. 15kΩ pull-up

See Guideline A in Cable and wire length guidelines.

ICOM n

Universal Input Common for all Universal Input terminals

Note: All Universal ICOMn terminals share a common, which is isolated from all other commons, except the SA bus common. One common screw terminal point is provided for every two input screw terminal points.

Same as (Universal) IN n

BINARY

(Inputs)

IN n

Binary Input - Dry Contact Maintained Mode

0.01 second minimum pulse width

Internal 18 V. 3k Ω pull-up

See Guideline A in Cable and wire length guidelines.

Binary Input - Pulse Counter/Accumulator Mode

0.01 second minimum pulse width

(50 Hz at 50% duty cycle)

Internal 18 V. 3kΩ pull-up

ICOM n

Binary Input Common for all Binary Input (IN) terminals

Note: All Binary ICOMn terminals share a common, which is isolated from all other commons.

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.

BINARY

(Output)

OUT n

Binary Output - 24 VAC Triac Class 2, 24 V, 500 mA (External Power Source)

Connects OUTn to OCOMn when activated.

External Power Source Requirements:

30 VAC maximum output voltage

0.5 A maximum output current

1.3 A at 25% duty cycle

40 mA minimum load current

See Guideline C in Cable and wire length guidelines.

OCOM n

Binary Output Common (for OUTn terminal)

Note: Each Binary Output Common terminal (OCOMn) is isolated from all other commons, including other Binary Output Common terminals.

CONFIGURABLE

(Output)

OUT n

Analog Output - Voltage Mode (0–10 VDC)

10 VDC maximum output voltage

or more.

See Guideline A in Cable and wire length guidelines

Binary Output - 24 VAC Triac (External Power Source only)

Connects OUTn to OCOMn when activated.

External Power Source Requirements:

30 VAC maximum output voltage

0.5 A maximum output current

1.3 A at 25% duty cycle

40 mA minimum load current

See Guideline C in Cable and wire length guidelines

OCOM n

Analog and Binary Output Signal Common All Configurable Outputs (COs) defined as Binary Outputs are isolated from all other commons, including other CO commons.

Same as (Configurable) OUT n
