Full 2000 V Input/Output/Power Isolation
Input and Output LoopTracker® LEDs
Output Test Button
Built-In Loop Power Supplies for Input and Output

Applications:

Convert, Boost, Rescale Process Signals
Isolate Single-Ended (Common Ground) PLC Inputs
Interface Signals with Panel Meters, PLCs, Recorders, Data Acquisition, DCS, and SCADA Systems

The API 4300 G are factory configured to accept a DC voltage or current input and provide an optically isolated DC voltage or current output that is linearly related to the input.

When a milliamp input is specified, a loop excitation power supply is included that may be wired for sinking or sourcing to allow you to use a powered or passive input device.

When a milliamp output is ordered, it provides power to the output current loop (sourcing).

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 test output level is factory set via an internal potentiometer to approximately 50% of output span. The functional test button greatly aids in saving time during initial startup and/or troubleshooting.

Installation

The API 4300 G plug into an industry standard 8-Pin octal socket sold separately. Sockets API 008 and fingersafe API 008 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.
