Installation and Operation Instructions

ACI/RH Duct and Outside Series

ACI

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. Caution: When using a 24 VAC transformer, ACI recommends that you use an

isolated transformer. If sharing the transformer with your controller, valve, actuator, or any other device, be sure to

connect all of the devices with the proper polarity, since most controllers are earth grounded. Failure to do so may

result in damage to the ACI/RH, your controller, or any other devices that are attached due to a ground loop problem.

The ACI/RH Duct and Outside transmitters are designed with a field selectable 4-20 mA, 0-5 VDC, or 0-10 VDC output

signal that is equivalent to 0 to 100% RH. Unless specified upon ordering, all units are shipped from the factory to

accept DC power with a 2-wire, 4-20 mA loop-powered output. Caution: When changing the Output Selection Switch

(SW3) make sure that the power supply is turned off before making any changes. Failure to do this may cause

damage to the unit.

 RH Duct and Outside Wiring Diagram (ACI Standard in Euro Housing)

ACI recommends that the ACI/RH 4-20 mA Duct and Outside relative humidity transmitters be wired with a two-wire,

16-22 AWG twisted pair or shielded cable for best results. All ACI/RH Duct and Outside voltage output or AC powered

current output transmitters should be used with a 3-wire, 16-22 AWG shielded cable. Note: When using a shielded

cable, be sure to connect only (1) end of the shield to ground at the controller. Connecting both ends of the shield to

ground may cause a ground loop.
