The API 4130 G L accepts a thermocouple input and provides an optically isolated and linearized DC voltage or current output. The thermocouple type, temperature span (°C or °F), and DC voltage or current output are factory configured.

Automatic cold-junction compensation and upscale burnout protection are standard, downscale burnout protection is optional.

The API 4130 G L features a thermocouple connection block on the side of the module. This allows direct temperature compensation at the T/C termination point eliminating cold junction errors.

The input is amplified, and then passed through an optocoupler to the output stage. Microprocessor-based linearization uses 41 to 55 segments or up to a 14th order polynomial depending on the sensor type. The low noise 16-bit (18-bit with HA option) analog output is isolated and can be set up for common voltage and milliamp output types.

Full 3-way isolation (input, output, power) make this module useful for ground loop elimination, common mode signal rejection, and noise pickup reduction.

Sourcing Output

The API 4130 G L has a 20 VDC loop excitation supply for the output. This power supply can be used to power a passive mA device.

LoopTracker

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

Output Test

An API exclusive feature includes an output test button to provide a fixed output (independent of the input) when held depressed. The output test greatly aids in saving time during initial startup and/or troubleshooting. The test output level is factory set at 50% of output span.

Mounting

The API 4130 G L plugs into an industry standard 8-Pin octal socket sold separately. Sockets API 008 and finger-safe API 008 FS allow either DIN rail or panel mounting.
