API 4130 GL Thermocouple Temperature Transmitters

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 GL 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.
