6.8.3
Analog Input Section
The analog section is takes advantage of the CPU’s on board 10bit ADC. This board can
support up to four load cells, three angle sensors and three length sensors.
6.8.3.1
Sensor Excitation Supply
The excitation supply provides power for all the sensors connected to the Analog section. The
nominal output is 4v (or 12V for 4-20mA transducers). Do not connect either the +VEX or
the –VEX outputs to any external supplies or chassis.
6.8.3.2
Load Cell Inputs
The analog input section is capable of accepting load cells with sensitivities of 1, 2 or 3mV/V.
Load cells of different sensitivities can be used on the one RCI-1550 at the one time. The gain
setting is controlled via software.
6.8.3.3
Angle Inputs
Either oil damped or electronic inclinometers can be connected to the RCI-1550’s angle
inputs. Note that all angle sensors must be the same type and may not be mixed. The analog
section must be configured, via a single jumper link to accept the appropriate type of sensor.
See connection diagram in rear of manual.
6.8.3.4
Length Inputs
The length inputs are designed to accept a 500
Ω
length sensor. No adjustments or
configurations are required on these inputs.
