Weight
F1 style: 1.04 kg (2.3 lb.)
S1 style: 1.25 kg (2.75 lb.)
Type Test Data
Dielectric Strength
Withstood 500 Vdc for 1 minute between chassis ground and the circuit grouping of the control power and RS-485
terminals.
Radio Frequency Interference (RFI)
Tested using a 5-wattt handheld transceiver operating at random frequencies centered around 144 MHz and 440
MHz with the antenna located within 6 inches (15 centimeters) of the device in both the vertical and horizontal
planes.
Vibration
Withstood 2 G over a range of 10 to 500 Hz for three hours in each of the three mutually perpendicular planes, 15
sweeps at 12 minutes each, for a total of nine hours of vibration. No structural damage or degradation of
performance was observed.
Shock
Withstood three 15 G shocks in each direction in each of the three mutually perpendicular planes for a total of 18
shocks.
Agency Certification
UL recognized per Standard 508.
FUNCTIONAL DESCRIPTION
The RDP-110C uses microprocessor-based technology to provide remote annunciation of engine and generator
parameters. RDP-110C function blocks are illustrated in Figure 2 and described in the following paragraphs.
Figure 2. RDP-110C Function Blocks
Inputs
RDP-110C inputs consist of a control power input, a communication interface, and pushbuttons. Control power
and communication connections are made on the circuit board attached to the front panel.
Control Power
The dc control power input is applied to an internal switching power supply that provides filtered 5 Vdc operating
power for the RDP-110C circuitry.
The control power input accepts nominal battery voltage of 12 Vdc or 24 Vdc. The acceptable range of dc control
power is 8 to 32 Vdc.
