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.InstallationThe 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.
