Description
The Q510 is a DIN rail mount,
RTD Input, dual or quad channel
two- wire transmitter. Each
channel accepts an RTD input
and provides an output loop
powered 4-20mA signal, linear
to the temperature input. Each
channel is an independent transmitter
with 600VDC channel to channel
isolation.
All
ActionI/Q modules feature SnapLoc
plug-in screw terminals for
easy installation and low Mean-Time-To-Repair
(MTTR). Two or more modules
can slide together and interlock
for solid, high density mounting
(remove either the foot, or
the adjacent unit's faceplate
for right-hand side or left-hand
hand side mounting, respectively).
The module to be attached will
easily slide on to the side
of the mounted unit.

Application
RTD input, two-wire transmitters
are used to convert a specific
temperature range into a regulated
4-20mA signal. Two-wire transmitters
are primarily used in remote
locations near the sensor since
they reduce the probability
of signal errors and save wiring
costs by utilizing the two power
wires to send the 4-20mA signal.
The current signal is usually
sensed by a control system or
displayed for an operator.
Typically,
several RTDs are used to measure
temperatures in a vessel or
cell. The lead wires can run
a short distance to a panel,
or farther with the use of shielded
wire, without errors caused
by noise or lead resistance
in the wires. These sensor wires
are then terminated at the two-wire
transmitter and converted into
a 4-20mA signal which is highly
immune to noise and not affected
by lead resistance, both of
which can cause significant
errors in voltage signals transmitted
over long distances.
