The ActionI/Q model Q510 is a DIN rail mount,
RTD Input, dual (2) or quad (4) channel two-wire transmitter. Each channel
accepts an RTD input and provides a output loop powered 4-20mA signal, linear
to the RTD temperature input. Each channel is an independent transmitter,
having 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). If desired, two or more modules can slide together and interlock for
solid, high density mounting. This is accomplished by removing either the foot,
or the adjacent unit's face plate, 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.
