Q510
Loop Powered Multi-Channel RTD Input

Up to 4 Two-Wire Transmitters in a Single Package
Output Linear to Input Temperature
Standard Input Ranges
Description
The Q510 is a DIN rail mount, RTD Input, dual or quad channel twowire 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.

Calibration
1. Connect the input to a calibrated three-wire resistance source
(not a resistance simulator). Connect the output in series to a
voltage source capable of supplying at least 20mA and a milliamp
current meter.
Set the calibrator to the specified minimum temperature resis-

tance value and adjust the zero potentiometer for 4mA output.
Note: The voltage source (Vs) connected to the output must be
sufficient to accommodate all other device loads (RL) in the
current loop:

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 420mA 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.
Operation
The Q510 operates as a two-wire transmitter; each channel derives
its power from a (10-35VDC) source connected in series with the
4-20mA output loop. Typically a 24VDC source is used, allowing
14VDC (700 ohms @ 20mA) for other devices connected in series
in the current loop. The outputs of the Q510 are protected from
reverse polarity. Zero and span pots are provided for each channel
to calibrate the output to the input RTD. Standard input temperature ranges (see Table) are calibrated to the rated accuracy. One
range per module; two or four channels per module.
3. Set the calibrator to the specified maximum temperature resistance value and adjust the span potentiometer for 20mA output.
4. Repeat steps 2 and 3, as necessary.
