The ActionI/Q DIN rail mount package was developed to reduce the cost of signal conditioning. The two primary design considerations were to house as many channels of isolated I/O as possible and to reduce the wiring requirements in terms of the number of power connections and I/O disconnects. The idea was that providing more I/O channels per module would reduce per channel material cost and the wiring savings would make cost of ownership low in the long run.

The result was a narrow ¾ inch, plug in, DIN rail mount package with the capability to fit two full size printed circuit boards and provide up to 22 terminals for plug-in I/O. The ActionI/Q now enables Action Instruments to provide some of the most cost effective signal conditioning and isolation solutions in the world. Examples include the four channel RTD transmitter (model Q510) and the four channel (4-20mA) loop powered isolator (model Q500), from the Original ActionI/Q Series of multi-channel transmitters.

DC Action I/Q
The DC Action I/Q Series is very similar to the AC ActionI/Q product line. The main difference is that the DC ActionI/Q line is DC powered, accepting 9 to 30V. The DC powered I/QRail is optional since the DC Action I/Qs have both DC power terminals as well as the power rail connector, unlike the AC ActionI/Q.
