Table 1. I/O terminal blocks, functions, ratings, requirements, and cables

Terminal block label

Terminal labels

Function, ratings, and requirements

To 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 35 mA total current.

Same as (Universal) INn.

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

INn

Analog Input - Voltage Mode (0–10 VDC)

10 VDC maximum input voltage

Internal 75k ohm Pulldown

See Guideline A in Table 1.

Analog Input - Resistive Mode (0–600k ohm)

Internal 12 V, 15k ohm pull up

Qualified Sensors: 0–2k potentiometer,

RTD (1k Nickel [Johnson Controls sensor],

1k Platinum, and A99B Silicon Temperature Sensor)

Negative Temperature Coefficient (NTC) Sensor

10K Type L (10K Johnson Controls Type II is equivalent to Type L) or 2.252K Type II

See Guideline A in Table 1.

Binary Input - Dry Contact Maintained Mode

1 second minimum pulse width

Internal 12 V, 15k ohm pull up

See Guideline A in Table 1.

ICOMn

Universal Input Common for all Universal IN terminals

Note: All Universal ICOMn terminals are isolated from all other commons.

Same as (Universal) INn.

BINARY

(Outputs)

OUTn

Binary Output - 24 VAC Triac (Internal Power)

Sources internal 24 VAC power (24~ HOT)

See Guideline C in Table 1.

OCOMn

Binary Output - 24 VAC Triac (Internal Power)

Connects OCOMn to 24~ COM when activated.

Internal Power Source:

30 VAC maximum voltage to load

0.5 A maximum output current

1.3 A at 25% duty cycle

40 mA minimum load current

See Guideline C in Table 1.

CONFIGURABLE

(Outputs)

OUTn

Analog Output - Voltage Mode (0–10 VDC)

10 VDC maximum output voltage

10 mA maximum output current

External 1k to 50k ohm load required

See Guideline A in Table 1.

Binary Output 24 VAC Triac

Connects OUT to OCOM when activated.

External Power Source:

30 VAC maximum voltage to load

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

Analog Output Signal Common: All Configurable Outputs defined as Analog Outputs share a common, which is isolated from all other commons except the Binary Input common.

Same as (Configurable) OUTn.

Binary Output Signal Common: All Configurable Outputs defined as Binary Outputs are isolated from all other commons, including other Configurable Output commons.
