A quick way to check the EGT probe is to disconnect it from whatever device you are using to read it & put an ohm meter across both output wires (the wire colors are usually red & yellow). If you get an open reading then the probe is probably bad. If you get somewhere between 3 to 12 ohms then it may still be okay.

It is not required, but if desired, a ½ Amp Fast Blow fuse can be used for each module.

No. The loop powered device requires a minimum of 4 mA to supply power to the module.

No. These should not be required for UL listing since the operating current and voltage are below the covered standards.

Yes, the API 4001 G SA-B, but the two RTDs will require very precise matching (±0.1%) and it would be helpful to know the operating temperature point so the factory can calibrate the unit precisely.

Yes, you can connect 2 of our API 1020 G units in series in the 4-20 mA input loop since the input impedance for current is 50 ohms and the drop is very low.

No. The highest outputs available are 100 mADC non-isolated (API 4010 G) and 50 mADC isolated (API 4300 G). The API 4300 G EXTSUP will sink up to 200 mADC with an external power supply.

Yes, however to utilize the charts for selecting the switch positions in the field, we need to convert °F to °C. This would give 550°C to 1100°C
