Terminal block label Terminal label Function, ratings, requirements Determine wire size and maximum cable length

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) INn

Note: Use 3-wire cable for devices that source power from the +15V terminal.

INn

Analog Input - Voltage Mode (0–10 VDC)

10 VDC maximum input voltage

Internal 75k ohms pull-down

See Guideline A in Table 1.

Analog Input - Current Mode (4–20 mA)

Internal 100 ohms load impedance. See Setting the Input Jumpers.

Note: A current loop fail-safe jumper must be in the Enable position to maintain a closed 4 to 20 mA current loop. See UI current loop jumpers.

See Guideline B in Table 1.

Analog Input - Resistive Mode (60–600k ohms)

Internal 12 V. 15k ohms pull-up

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

See Guideline A in Table 1.

Binary Input - Dry Contact Maintained Mode

1 second minimum pulse width

Internal 12 V. 15k ohms pull-up

See Guideline A in Table 1.

ICOMn

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) INn

BINARY

(Inputs)

INn

Binary Input - Dry Contact Maintained Mode

0.01 second minimum pulse width

Internal 18 V. 3k ohms pull-up

See Guideline A in Table 1.

Binary Input - Pulse Counter/Accumulator Mode

0.01 second minimum pulse width

(50 Hz at 50% duty cycle)

Internal 18 V. 3k ohms pull-up

ICOMn

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)

OUTn

Analog Output - Voltage Mode (0–10 VDC)

10 VDC maximum output voltage

10 mA maximum output current

Required an external load of 1,000 ohms or more.

Note: The Analog Output (AO) operates in the Voltage Mode when connected to devices with impedances greater than 1,000 ohms. Devices that drop below 1,000 ohm may not operate as intended for Voltage Mode applications.

See Guideline C in Table 1.

Analog Output - Current Mode (4–20 mA)

Requires an external load between 0 and 300 ohms.

Note: The Analog Output (AO) operates in the Current Mode when connected to devices with impedances less than 300 ohms. Devices that exceed below 300 ohms may not operate as intended for Current Mode applications.

OCOMn

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)

OUTn

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 Table 1.

OCOMn

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.
