Figure 11 HMDW110 Wiring With RDP100 Remote Display Panel
You must always connect the humidity measurement current loop (
HUM
, terminals 5 and 6) to
power the transmitter. Connecting the temperature measurement current loop (terminals 7
and 8) is optional.
Connect the RDP100 remote display panel using terminals 1 ... 4. The HMDW110 series
transmitter provides both power and data to the RDP100.
Terminals 1 ... 4 shall be used only for connecting the RDP100 (optional) when
using the analog outputs. If the RDP100 is not used, terminals 1 ... 4 must be left
unconnected. Otherwise the analog outputs may output incorrect readings.
The GND input of the RDP100 must be connected only to terminal 3 of the
HMDW110 transmitter. It must not be connected to any local ground potential.
