| DI-5B40 Analog Voltage
Input Modules Wide Bandwidth |
Product Highlights
Each DI-5B40 wide bandwidth voltage input module provides
a single channel of analog input which is amplified, isolated,
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-5B40 module is designed with a completely isolated
computer side circuit which 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 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 10kHz. 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%.
A special input circuit on the DI-5B40 provides protection
against accidental connection of power-line voltages up
to 240VAC.
