4 Channel Inertia Dyno
Electronics Kit
 
Software and electronics
kit for inertia dynamometers. Suitable for making dynamometers for RC
Cars, Motorcycle, Karts, Car, Engines, Motors, (No mechanical parts
included)
-
IDERC4 Data Acquisition Unit.
4 Channels.
-
Inductive pickup to measure
roller rpm.
-
Installation cables.
-
Latest RacingDyno
software (on CD or downloaded to your PC).
For DIY dynamometers, just manufacture the mechanical parts; install the
RacingDyno
software and then plug and play. All type of engines or motors could be
tested if it is possible to transfer the torque to the flywheel. The prototype
Basic version is obsolete! The latest RacingDyno
software
will be given free with the electronics. This version allows measuring
power and torque outputs as well as other new functions.
Our electronic kit is better
than others usual "data logger" systems that
does the reading in 1 session then the analyzing in another session The
IDERC4 unit does the data logging and analyzing simultaneously. You will
see the results on the fly!
What's new?
-
2 Additional General Purpose
auxiliary channel, analog 0-5V ( suitable for lambda probe). Total 4 Channels
all together..
Features.
-
4 Channel Data Acquisition Unit
-
2 auxiliary channel inputs 0-5V
/ 60Hz
-
Engine RPM, Volts, Temp, CO,
O2, etc and other parameters available with use of additional channels.
RacingDyno software supported)
-
RacingDyno
Software available for "Engine RPM". ("Engine Torque" is derived from engine
gear ratio, not Roller Torque).
-
Real time on screen display
test results. Tests appears in the screen while the engine accelerates.
-
See graphs simultaneously: show
or hide any curve.
-
Really accurate and detailed
curves: detect engine failures easily.
Software
This unit use the RacingDyno
software for windows. Its development is based on over then 5 years
of user feedback and research. It is very powerful and easy to use.
Please read more of our latest
version of the RacingDyno
software.
Specifications
Power supply : Self
Powered via computer port RS232. No power cables needed.
( However in the case of
using external sensors that derive high power from its source, external
power is needed to cover up the power supplied by the PC com Port. If signs
of insufficient power supply or unstable data reading is detected, we would
suggest an external power supply).
Local power adapter with
output of 9VDC 300mA, center post +ve, outer Gnd, could also be used. We
can also provide suitable power adapters (Please specify local power supply
either 120VAC or 240VAC).
No power supply will be needed
for IDERC1 as it is only a single channel unit.
Please determine the power
dissipation of the external sensors used.
External power is not needed
if no reading error is detected (most likely due to insufficient power
supply by the PC serial com).
Data transfer : 9600
baud RS232C (DB9 Con). Connection is done via PC serial port, this makes
it very easy to connect this unit to any computer.

Installation and Connections
IDERC4 LAYOUT
ROLLER CHANNEL CONNECTION
Roller Channel - roller
pickup connection. pick-up should be mounted properly to ensure the
inductive pickup (or optical pickup) gets good signal from the roller.
Due to physical mechanical
constraints, the maximum frequency for the roller is suggested to max out
at 5000RPM and should not exceed 6000RPM. However , because the IDERC4
unit could accept frequency up to 15kHz (900,000RPM), with 5000RPM max
roller frequency, up to 180 signals/pulses could be used (120 suggested).
Therefore it is possible
to have 180 signals per roller revolution for more accuracy.
A typical roller configuration
of a RC car Chassis dynamometer is a roller with a flywheel disc of 50
holes and optical pickup.
A typical roller configuration
of a motorcycle dynamometer is a roller with 130 geared teeth and inductive
pickup.
Note : Please indicate
to us your expected max frequency for the roller channel (number of signals
per second expected). This is so we could set up the channel for best performance.
The idea is so we could use more than 80% of the full swing of the Roller
Channel frequency. Setup has to be done in the factory. (more..)
ANALOGUE INPUT CHANNEL - CH3
& CH4
Channel 3 and Channel 4 is
available for signal input of 0-5V/60Hz. This can be used to connect several
other automotive sensors to the IDERC4 unit. As an example above is to
connect a lambda probe such as the Bosch LSM11.
An external +5VDC supply
is also available for use with the sensor if needed.
