Action Instruments IQ Limit Alarms - Signal Conditioners

Original Action I/Q Series
These DC-powered, fixed ranged, multi-channel signal conditioners and isolators offer stable 0.1% accuracy over operating ambient temperature range of 20 to 80°C. Their multi-channel design ensures high density and low material cost. Plug-in terminal sockets makes wiring quick and easy. To isolate a powered 4-20 mA loop, the Q500 loop powered isolator is available for one, two or four channel applications. Direct DC inputs, voltage or current, can be specified by range for the Q501 two-wire transmitter with 4-20 mA output, available in one or two channels.

Action I/Q Series Limit Alarms
The AC-powered Action I/Q Series of limit alarms offers many of the most advanced microprocessor and ASIC based signal conditioning solutions available. Field configurable and wide ranging, these modules are an off the shelf solution for most limit alarm applications. Models are available for DC, RTD or thermocouple signal input applications.

DC Action I/Q
The DC-powered Limit Alarm uses a flexible 0-30 VDC power supply. The DC-powered I/Q Rail is optional since the DC Action I/Qs have both DC power terminals as well as athe power rail connector, unlike the AC Action I/Q models.
