Absolute Process Instruments API 4406 G _ Fully isolated. Inputs share

Cecomp Electronics, API 4406 G, Isolated DC to DC Math Function Transmitter, (A+B-C)/2

Features:

Factory Set Custom I/O Ranges
Easy-to-Install Plug-In Design
Full 2000 V Input/Output/Power Isolation
Input and Output LoopTracker® LEDs
Output Test Button

Applications:

Add, Subtract, Average Flow Signals
Average Multiple Signals

The API 4406 G are factory configured to accept two to four DC voltage or current inputs and provide an optically isolated DC voltage or current output that is proportional to the sum, average and/or difference of the inputs depending on the model.

The A, B and C inputs should be the same type, and mixed input ranges are allowable. Consult the factory when selecting mixed input ranges.

Inputs are converted to a percentage and then the math function is applied. Consult the factory if true voltage math is required.

The API 4406 G uses no transformers or choppers in the signal path for best noise immunity and freedom from AC artifacts in the output. The inputs are not isolated from each other and use the same signal common connection. The modules do features full 3-way (input, output, power supply) isolation.

Common ranges as well as custom ranges are possible.

LoopTracker

API exclusive features include two LoopTracker LEDs (green for input, red for output) that vary in intensity with changes in the process input and output signals. These provide a quick visual picture of your process loop at all times and can greatly aid in saving time during initial startup and/or troubleshooting.

Output Test

An API exclusive feature includes the Functional Test Button to provide a fixed output (independent of the input) when held depressed. The output test level is adjustable from 0 to 100% of output span. The functional test button greatly aids in saving time during initial startup and/or troubleshooting.

Installation

The API 4406 G plug into an industry standard 11-Pin octal socket sold separately. Sockets API 011 and finger-safe API 011 FS allow either DIN rail or panel mounting. The plug-in design, 3-way isolation, and robust electronics allows the module to be quickly hot-swapped without removing the power or I/O signals.
