The field configurable AP6380 signal conditioner offers wide ranging input capability for scaling, converting or isolating AC inputs ranging from 5mA AC to 100mA AC or 50mV AC to 200V AC. The DC output of the AP6380 is proportional to the average of the fully-rectified AC input signal, and is calibrated for sine waves from DC to 1KHz.

For current inputs above 100mA AC, it is recommended that an input shunt resistor be used and the AP6380 be configured for the proper input voltage range. For example, for a 5A AC current transformer output, use the Action model C006 resistor (0.1W, 5W, 1%) and set the input for 0-500mV AC.

Application

The Action Pak AP6380 is useful in applications requiring a conditioned DC output from an AC source. Typical applications include energy management, load shedding, motor current/load

monitoring, locked rotor detection, isolation and data acquisition. The output of the AP6380 can drive a digital meter for direct display or can interface with alarming or control devices including

PLCs and computers.

Diagnostic LED

Input power and signal status are indicated with a dual-function LED on the AP6380. The green LED will illuminate when line power is applied, and will pulse quickly (8 Hz) if the input rises 10% above the set input full scale range. If this continues to occur, you may wish to change your full scale input range setting.

Configuration

The AP6380 can be set for a wide variety of full scale input ranges. The factory pre-sets the AP6380 with an input range of 0-500mV AC (SW1 & W2) and an output range of 4-20mA DC (SW2) as shown in Figure 1. For other I/O ranges, remove the four base screws to access the I/O range configuration selectors. The line power is preset at the factory for 120V AC. This may be reconfigured by referring to figure 2.

Warning: Do not change switch settings with power applied.
