APD 1393 Series RTD to DC Signal Splitters

The APD 1393 IsoSplitter accepts an RTD temperature input and provides two optically isolated and linearized DC voltage or current outputs. The sensor type and temperature range and each independent output range can be specified as required. This provides an economical solution when one temperature signal must be sent to two different devices.

Typical applications include validation, datalogging, output device separation and redundancy (i.e. to prevent failure of the entire loop if one device fails), or a combination of these. The temperature input is linearized, amplified, split, and then passed through an opto-coupler to the output stages. Full 4-way isolation (input, output 1, output 2, power) make this module useful for ground loop elimination, common mode signal rejection, and noise pickup reduction.
