Space Combination Temperature/Humidity Transmitter 3
Publication 1414-IN018A-EN-P - October 2005
Install the Combination Transmitter
Transmitters can be mounted directly on a wall or to a wall box. For the most
accurate results, units should be mounted on an inside wall to a wall box,
approximately 3 to 5 feet from the floor, away from any supply air exhausts and
other sources of heat or cold. The enclosure cover is held in place with a locking
tab located to the left of center at the bottom of the enclosure. After installation the
cover can be locked on with the set screw (1/16” or 1.5 mm) at the bottom of the
enclosure.
Wire and Connect the Combination Transmitter
Anti-static precautions should be followed to prevent damage to the device.
The transmitter should be connected to the controller using twisted-pair 18 to 22
AWG wire and requires two wires for DC 4 to 20 mA loop-powered operation. Use
shielded cable for the highest noise immunity. Do not route signal wires in the
same conduit with power cables as signal degradation may occur. The controller
Analog Input (AI) must be selected to match the transmitter output before power is
applied. The AI type must be a current input with 250 or 500 ohm impedance. All
transmitters have an operating range of 0 to 70 °C (32 to 158 °F) The transmitter
board should not be mounted where temperatures will exceed these values. See the
connection diagram for more details.
Wire Connections For the Combination Temperature/Relative Humidity Boards
The temperature sensor option output is on the two terminals marked TEMP.
Typical wiring to a controller is shown in the connection diagram.
For 4 to 20 mA loop signal, only the PWR and OUT terminals are used.
