| API Industry Cross Reference |
Replace your old signal conditioners with our lifetime warranty units.
Some competitive models have been discontinued or have extremely long lead times. We can replace them quickly!
To ensure compatibility, please specify input, output, alarm specifications (for alarm units), and module power and any additional info from the model you are replacing.
Models with same series numbers (i.e. 4380) should be directly compatible, but please check ranges, wiring, and power for compatibility.
If you have a competitive model not listed here, we can probably fine a compatible replacement. For example some companies may have made a 1040 in the past and it is probably compatible with ours.
