Product Highlights
Each DI-5B42 2-wire transmitter interface module provides
a single channel that accepts a 4 to 20mA process current
input and provides a standard +1 to +5V output signal.
An isolated +20VDC regulated power supply is provided
to power the current transmitter. This allows a 2-wire
loop powered transmitter to be directly connected to the
DI-5B42 without requiring an external power supply. The
regulated supply will provide a nominal +20VDC at a loop
current of 4mA to 20mA.
The DI-5B42 will provide a 1500V isolation barrier for
non-isolated 2-wire field transmitters. It can also be
used when additional isolation is required between an
isolated 2-wire transmitter and the input stage of the
control room computer.
The voltage output is logic-switch controlled, allowing
these modules to share a common analog bus without the
requirement of external multiplexers.
The DI-5B42 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.
A precision 20O current conversion resistor is supplied
with the module. All field inputs are fully protected
from accidental connection of power-line voltages up to
240VAC. The module has a 3dB bandwidth of 100Hz. Signal
filtering is accomplished with a six-pole filter, with
two poles on the field side of the isolation barrier,
and the other four on the computer side.
