| DI-5B43 Isolated DC
Transducer Amplifier Input Modules |
Product Highlights
Each DI-5B43 displacement transducer module provides a
single channel of displacement transducer input which
is filtered, isolated, scaled, and converted to a high
level analog voltage output. This voltage output is logic-switch
controlled, allowing these modules to share a common analog
bus without the requirement of external multiplexers.
The DI-5B43 module is designed with a completely isolated
computer side circuit that can be floated to ±50V
from power common (pin 16). This complete isolation means
that no connection is required between I/O common and
power common for proper operation of the output switch.
The DI-5B43 can interface to DC displacement transducers
and other devices which require a precision 10VDC supply
and produce a high level output. The 1kHz bandwidth significantly
reduces ripple and noise inherent in these devices.
Transducer excitation is provided from the module by a
very stable 10V source. The excitation supply is fully
isolated, allowing the amplifier inputs to operate over
the full range of the excitation voltage. This feature
offers significant flexibility in real world applications.
Eight full scale input ranges are provided, from ±1V
to ±8V, producing ±5V full scale output.
The input signal is processed through a pre-amplifier
on the field side of the isolation barrier. This pre-amplifier
has a gain-bandwidth product of 5MHz and is bandwidth
limited to 1kHz. After amplification, the input signal
is chopped by a proprietary chopper circuit. Isolation
is provided by transformer coupling, again using a proprietary
technique to suppress transmission of common mode spikes
or surges. The module is powered from +5VDC, ±5%.
Special input circuits on the DI-5B43 provide protection
of the signal inputs and the isolated excitation supply
up to 240VAC.
