Action Pak units are compact, electronic plug-in modules.
AP1000 Series Field Configurable Alarms
The AP1000 series limit alarms receive direct sensor inputs and operate from 120V AC (or optionally on 24V DC on some models). They provide the broad range of limit alarm and control capabilities required
in today's industrial processes. The AP1000 series dedicated singlechannel limit alarm provides excellent single-point control with proven reliability.
The DC input AP1080/90, the thermocouple input AP1280/90 and the AC input AP1690 can all be configured in the field by setting DIP switches for input range or type, alarm function (HI/LO) and alarm state (failsafe/non-failsafe). This minimises spare parts inventory and provides an off-the-shelf solution for virtually any alarm function.
AP4000 - AP9000 Series Four-wire Transmitters
The AP4000 to AP9000 series signal conditioners are compact, electronic, plug-in modules that take direct sensor inputs and signals and convert them into useful high level signals. They operate from 120V AC power (or optionally on 24V DC on some models).
The AP4000 series four-wire transmitters typically operate from external AC line power and require two wires for that operating power and two wires for the output signal. Outputs are conventional DC
process signals, such as 4-20mA or 0-10V, and are compatible with all important process instrumentation equipment, including other Action
Pak modules. When AC power is impractical or not available, most 4000 series modules are available with a DC option so that they can be operated from a 24V DC source.
