The APD 4403 D provide an optically isolated DC voltage or current output that is calculated from the mathematical function built in to the module.
Full 3-way isolation (input, output, power) makes this module useful for ground loop elimination, common mode signal rejection or noise pickup reduction. The inputs are not isolated from each other.
The APD 4403 D Transmitters can be wired to allow a mA output to be either sinking (passive) or sourcing (active).
LoopTracker
API exclusive features include a green LoopTracker LED that varies in intensity with changes in the process input signal. It provides a quick indication of your process input at all times and can greatly aid in saving time during initial startup and/or troubleshooting.
Functional Test
An API exclusive feature includes the Functional Test Button to provide a fixed output (independent of the input) when enabled. The test output level is potentiometer adjustable from 0 to 100% of output span. The functional test button can greatly aid in saving time during initial startup and/or troubleshooting.
