ACTIONI/Q® Q510 Loop Powered Multi-Channel RTD Input Isolating, 2-Wire Transmitter

Provides 2 or 4 Current Loop Outputs in Proportion to the PT100 Ohm RTD Inputs.

  • Up to 4 Two-Wire Transmitters in a Single Package
  • Output Linear to Input Temperature
  • Standard Input Ranges
  • High Density DIN Rail Mounting
  • SnapLocTM Plug-in Terminals
  • Output Loop Powered from 10 to 35VDC
Q510-0xxx (2 Channel)
Q510-4xxx (4 Channel)

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.

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.
