4.1 in. (10.4 cm)

2.24 in (5.69 cm)

To wire an external power supply to the expander

An external power supply is required to power the expander.

WARNING Do not apply line voltage (mains voltage) to the controller's ports and terminals.

CAUTIONS

•The TV-UCXPIO48 is powered by a Class 2 power source. Take appropriate isolation measures when mounting

it in a control panel where non-Class 2 circuits are present.

•Carrier controllers can share a power supply as long as you:

•Maintain the same polarity.

•Use the power supply only for Carrier controllers.

To wire the power supply to the expander

1 Make sure the TV-UCXPIO48’s power switch is in the OFF (down) position to prevent it from powering up

before you can verify the correct voltage.

2 Remove power from the power supply.

3 Pull the red screw terminal connector from the expander's power terminals labeled 24 V (+/-).

4 Connect the power supply's wires to the red screw terminal connector.

5 Connect an 18 AWG or larger wire from the power supply's negative (-) terminal to earth ground. This wire

must not exceed 12 in. (30.5 cm).

6 Apply power to the power supply.

7 Measure the voltage at the red screw terminal connector to verify that the voltage is within the operating

range of 20 to 30 Vac or 23.4 to 30 Vdc.

8 Insert the red screw terminal connector into the expander's power terminals.

9 To verify the polarity of the wiring, measure the voltage from the negative terminal of the red screw terminal

connector to a nearby ground. The reading should be 0V.

10 Turn on the TV-UCXPIO48's power switch.

11 Verify that the PWR LED on top of the expander is on.

To wire the expander for communications

Wiring restrictions for connecting the expander to the controller

○Maximum length: 1000 feet (305 meters)

○22 or 24 AWG, low-capacitance, twisted, stranded, shielded copper wire

WARNING Do not apply line voltage (mains voltage) to the expander's ports and terminals.

1 Turn off the controller's and expander's power.

2 Wire the expander's I/O Bus port to the same port on the controller.

NOTE Use the same polarity throughout the network segment.

3 Set the I/O Bus End of Net? switch to Yes to apply network termination and bias.

NOTE The controller has built-in I/O bus network termination.

4 Turn on the controller's and expander's power.

1 Turn off the power switch on the controller that the TV-UCXPIO48 is attached to.

2 Set the TV-UCXPIO48's address on the rotary switch to 1as shown below.

3 Turn on the controller's power switch. The controller reads the TV-UCXPIO48's address each time you turn on

the controller's power.

Platinum 1kOhm at 32°F (0°C) (0.00375 TCR)

•Nickel-iron 1kOhm at 70°F (21°C)

•Platinum TS-8000 1kOhm at 32°F (0°C) (0.00385 TCR)

•Balco (nickel-iron) TS8000 1kOhm at 70°F (21°C)

Input voltages should be from 0.3–0.68V.

NOTE

Carrier recommends use of an external current transducer between an RTD and the

TV-UCXPIO48 to improve accuracy and resolution.

Pulse counter 2Pulse counting up to 40 pulses per second.

Minimum pulse width (on or off time) required for each pulse is 12.5 msec.

1To use a thermistor or RTD not listed above, you can set up a custom translation table for your sensor in the

controller's driver.

2The TV-UCXPIO48 can perform pulse counting for dry contact or voltage inputs if you assign the input to a Pulse

to Analog Input microblock. See To adjust input and output properties (page 15).

WARNING Do not apply voltage to any input configured for 0-20 mA as this could damage the expander.

Wiring inputs and outputs

Outputs

The TV-UCXPIO48's universal outputs can be set as analog or binary on their two DIP switches.

The expanders' outputs return to their unconfigured state if they are removed from the program or the program is

deleted from the controller. Also, outputs time out and return to their unconfigured or off state after two minutes of

inactivity. The unconfigured state results in:

•Not running control programs that are due to download

•Losing power to the controller, but not the expander

NOTE This does not apply to outputs that have been locked in the i-Vu® application.

Analog outputs

Outputs set up as analog can be used for:

•0-10 Vdc devices

•0-20 mA devices

WARNING Do not apply voltage to any output whose DIP switch is set to Analog.

If output controls a...

Resistance to ground must be...

0–10 Vdc device 500 Ohms minimum

0–20 mA device 500 Ohms maximum

NOTE The device must share the same ground as the expander.

Binary outputs

The outputs have a built-in relay and provide a dry contact so an external voltage source must be wired to one of

the two terminals.

Outputs set up as binary can be used to switch external devices and relays up to 1A, 30 Vac/Vdc.

NOTES

•Carrier recommends use of an external current transducer between an RTD and the TV-UCXPIO48 to improve

accuracy and resolution.

•RTD inputs require either sensor calibration or an estimated offset correction for wiring resistance. See Offset

and Polarity values (page 19).

Output wiring

To size output wiring, consider the following:

•Total loop distance from the controller to the controlled device

NOTE Include the total distance of actual wire. For 2-conductor wires, this is twice the cable length.

•Acceptable voltage drop in the wire from the controller to the controlled device

•Resistance (Ohms) of the chosen wire gauge

•Maximum current (Amps) the controlled device requires to operate

To wire inputs and outputs

WARNING Do not apply line voltage (mains voltage) to the controller's ports and terminals.

1 Verify that the TV-UCXPIO48's power and communications connections work properly.

2 Turn offthe TV-UCXPIO48's power.

3 Connect the input wiring to the UI screw terminals on the TV-UCXPIO48.

WARNING Do not apply voltage to any input configured for 0-20 mA as this could damage the expander.

NOTE Connect the shield wire to the - terminal with the ground wire. Do not connect the shield wire at the

other end of the cable as this will cause a ground loop error.

CAUTION Outputs are set to Binary in the factory. To avoid damage to the expander, use a voltmeter to

verify there is no voltage on the + and - terminals before setting the DIP switch to Analog.

6 Turn on the TV-UCXPIO48's power.

See Troubleshooting inputs and outputs (page 22).

An input or output must be assigned to its corresponding point in the control program. This is typically done when

the control program is created, but you can adjust the settings at the time of installation in the i-Vu® interface.

1 In the i-Vu® User tab, select the equipment controlled by the TV-UCXPIO48.

2 On the Properties page, select the I/O Points tab.

3 For each point, type the expander's rotary switch address in the Exp field and the number of the expander's

corresponding input or output in the Num field.

EXAMPLE If UO-01 on the TV-UCXPIO48 (which has a rotary switch address of 1) is used for the point Fan

S/S, enter 1:1 in the Exp:Num column for Fan S/S.

NOTEDo not assign the same output number to more than one point.

4 Enter the appropriate values for each input and output in the remaining columns. See Input values, Output

values, Resolution values and Offset/Polarity values below.

CAUTION Do not assign two input microblocks to the same physical input using Dry Contact in one and

Binary Input in the other. This results in faulty behavior.

5 If you have not performed the initial download to the attached controller, you must download now to verify

inputs and outputs.

6 To verify each input's operation, force each sensor to a known value, then compare it to the Value shown on

the Properties page on the I/O Points tab.

7 To verify each output's operation, lock each output to a known condition on the I/O Points tab, then verify that

the equipment operates correctly.

1The sensor reads a value and sends a corresponding signal (Volt or mA) to the TV-UCXPIO48's physical input. The

Analog Input microblock uses the Min and Max values to linearly translate the signal into the engineering value

used in subsequent control logic. For example, set Min to 0 and Max to 10 for a 4–20 mA sensor that measures

velocity from 0.0 to 10.0 inches/second so that when the input reads 4 mA, the microblock outputs a value of 0.

Similarly, when the input reads 8 mA, the microblock outputs a value of 2.5.

2You can set up a custom translation table on the driver's Custom Translation Tables pages in the i-Vu® interface.

3 The control program must have one Pulse to Analog Input microblock for each pulse counting input.

4To improve the accuracy for RTD sensors used with long cables, see Offset/Polarity values (page 19).

5Binary Input and Dry Contact input types are not interchangeable. Setting an input to Dry Contact applies a

wetting voltage to sense a dry contact. Setting an input to Binary Input will not apply a wetting voltage.
