DIN Rail Analog Output Module Crestron DIN-AO8

Calculate

Power

CAUTION: Use only Crestron power supplies for Crestron equipment.

Failure to do so could cause equipment damage or void the Crestron

warranty.

CAUTION: Provide sufficient power to the system. Insufficient power

can lead to unpredictable results or damage to the equipment. Please use

the Crestron Power Calculator to help calculate how much power is

needed for the system (

www.crestron.com/calculators).

When calculating the length of wire for a particular Cresnet run, the wire

gauge and the Cresnet power usage of each network unit to be connected

must be taken into consideration. Use Crestron Certified Wire only. If

Cresnet units are to be daisy-chained on the run, the Cresnet power usage

of each network unit to be daisy-chained must be added together to

determine the Cresnet power usage of the entire chain. If the unit is

home-run from a Crestron system power supply network port, the

Cresnet power usage of that unit is the Cresnet power usage of the entire

run. The wire gauge and the Cresnet power usage of the run should be

used in the following equation to calculate the cable length value on the

equation’s left side.

Cable Length Equation

Make sure the cable length value is less than the value calculated on the

right side of the equation. For example, a Cresnet run using 0.75mm

(18 AWG) Crestron Certified Wire and drawing 20 watts should not have

a length of run more than 101 meters (333 feet). Cresnet-HP cannot be

used.

NOTE: All Crestron certified Cresnet wiring must consist of two

twisted pairs. One twisted pair is the +24V conductor and the GND

conductor and the other twisted pair is the Y conductor and the Z

conductor.

Strip and Tin

Wire

When daisy-chaining Cresnet units, strip the ends of the wires carefully

to avoid nicking the conductors. Twist together the ends of the wires that

share a pin on the network connector and tin the twisted connection.
