Specifications – Installation and Operating Instructions
The Series RHPLC Wall Mount
Humidity/Temperature Transmitter is a compact economical sensor for the
building automation market space. The stylish housing is well vented to
provide airflow across the sensor to improve measurement accuracy.
Each unit utilizes a capacitive polymer sensing element to deliver a
proportional analog output. A combination humidity and temperature model can
be configured with current, voltage, RTD, or thermistor output. A wide
selection of passive RTD or thermistor temperature sensors is available in
this series.
BENEFITS/FEATURES
- Reduced installation cost with combined humidity and temperature sensing
- Wide application environments from a large selection of temperature sensors and 2% to 3% accuracies
APPLICATIONS
- Air economizers
- Room comfort monitoring

INSTALLATION
WARNING Disconnect power supply before installation to prevent electrical
shock and equipment damage Make sure all connections are in accordance with
the job wiring diagram and in accordance with national and local electrical
codes. Use copper conductors only.
CAUTION Use electrostatic discharge precautions (e.g., use of wrist
straps) during installation and wiring to prevent equipment damage.
CAUTION Do not exceed the ratings of this device, permanent damage not
covered by warranty may result. The 4-20 mA models are not designed for AC
voltage operation.
NOTICE Avoid locations where severe shock or vibration, excessive
moisture or corrosive fumes are present.
MOUNTING
- Push the tab on the top and bottom of the cover and lift the cover from the back plate (See Figure 1).
- Select the mounting location, away from diffusers, lights, or any external influences.
- Mount the transmitter on a vertical surface to a standard electrical box using the two #6
- M2C type screws provided.
- Pull wires through the sub-base hole and make necessary connections.
- Reattach the cover to the base plate
Wiring
Use a minimum of 22 AWG to a maximum of 18 AWG wire for wiring to terminals.
Refer to Figures 2 and 3 for wiring information.
Current Output Models: Wire as shown in Figure 2. Current outputs must be
powered with 10-35 VDC. If the RH output is not required, wire the negative
terminal of the
power supply to terminal 1 of the transmitter. If the unit has a passive
temperature sensor, wire to terminals 3 and 4.
Voltage Output Models: Voltage outputs may be powered with 10-35 VDC (0-5 V models), 15-35 VDC (0-10 V models) or 10-29 VAC (0-5 V modes), 15-29 VAC (0-10 V models). Note polarity when using DC power. Wire the RH voltage output as shown in Figure 3. If the unit has a voltage temperature output, wire the temperature receiver between terminal 4 and the negative terminal of the power supply. If the temperature or RH voltage output is not used it may be left disconnected. If the unit has a passive temperature sensor, wire to terminals 4 and 5.
TROUBLESHOOTING
- Verify that the unit is mounted in the correct position.
- 4-20 mA Models: Verify appropriate supply voltage. The transmitter requires a minimum of 10 and a maximum of 35 VDC at its connections for proper operation. Choose a power supply with a voltage and current rating which meets this requirement under all operating conditions. If the power supply is unregulated, make sure voltage remains within these limits under all power line conditions. Ripple on the supply should not exceed 100mV.
Loop Resistance – The maximum allowable loop resistance depends on the power supply voltage. Maximum loop voltage drop must not reduce the transmitter voltage below the 10 VDC minimum. Maximum loop resistance can be calculated with the following equation. VPS is the power supply voltage.
Some receivers, particularly loop-powered indicators, may maintain a fixed loop voltage to power the device. This voltage drop must also be subtracted from the power supply voltage when calculating the voltage margin for the transmitter. The following equation takes this into account. Vic is the receiver’s fixed voltage.
Voltage Output Models:
Verify appropriate supply voltage. The voltage output models require a 10-35
VDC (0-5 V models), 15-35 VDC (0-10 V models) or 10-29 VAC (0-5 V modes),
15-29 VAC (0-10
V models) for proper operation maximum. The maximum output load is 5 mA.
MAINTENANCE/REPAIR
Upon final installation of the Series RHPLC, no routine maintenance is
required. The Series CDWP is not fielded serviceable and is not possible to
repair the unit. Field repair
should not be attempted and may void the warranty.
