Output to Controller

+8 to 35 VDC

All ACI/TT and TTM temperature transmitters can be powered from either an unregulated or regulated +8 to 35VDC

power supply. Several transmitters may be powered from the same supply as shown below. Each transmitter could

draw 22mA. To determine the number of transmitters use the following formula:

N =

mA22

where: N = number of transmitters

I = current available from power supply

22mA = maximum current draw of transmitter

e.g., If I = 1.5A then:

N = 1.5/22mA

N = 68

Therefore a 1.5A power supply will safely power up to 68 transmitters.

All ACI/TT, TTM, and ACI/TTU temperature transmitters are non-polarity sensitive. That means that either the

positive and negative outputs of the power supply can be connected to either side of the power terminal block. ACI

transmitters will also accept AC power only if specified when ordering. The output must be specified as a +1-5 or

+2-10 for this option when ordering the transmitters.

ACI Installation and Operation Instructions ACI/RH Duct and Outside Series Automation Components, Inc. Please Read Instruction Carefully Before Installation! The ACI/RH Duct and Outside series transmitters are a universal Relative Humidity transmitter that can be powered with either a +15 to 36 VDC or 24 VAC supply voltage. The ACI/RH uses a half-wave bridge rectifier to convert the AC power to a useable DC voltage.

Decrement RH Output - This DIP switch will allow you to calibrate the sensor through the software. The switch must be toggled from the Off to the On position and then returned to the Off position for a decrease of 0.5% RH. This means that if your humidity has drifted 1% over a certain time period, you will be able to toggle the Decrement RH Output switch 2 times in order to slide the whole curve downward. Note: This is only a single point calibration, and is not recommended for critical applications.

5. 6. 7. Now make sure that all of the dipswitches are properly configured as per Figures #2, #3, #5, and #6 before initially powering the unit. Now place the cover onto the unit and gently turn until it is tight. Be careful not to apply too much pressure when tightening. Now verify that you are getting a humidity reading on your Building Automation System. Please note that it may take ten to twenty minutes for the sensor reading to stabilize upon initial power up.

nROOM TEMPERATURE TRANSMITTERS This unit is suitable for either drywall or junction box mounting. First, remove the cover of the housing and mount the base of the Room unit to the wall, using the (2) 6/32” x 1” screws that are provided. Once the base is mounted to the wall, make all of the proper connections and then place the cover back onto the unit. Now tighten the cover down, using the (2) 1/16” Allen screws located in the bottom of the housing.
