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.

Output Sink/Source Versatility

Standard on the APD 1393 are 20 VDC loop excitation supplies for each output channel. These power supplies can be selectively wired for sinking or sourcing allowing use with any combination of powered or unpowered milliamp devices.

LoopTracker

API exclusive features include three LoopTracker LEDs (green for input, red for each output) that vary in intensity with changes in the process input and output signals. These 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 output test buttons for each channel to provide a fixed output (independent of the input) when held depressed. A test button is provide for each output channel. The output test greatly aids in saving time during initial startup and/or troubleshooting. The test output level for each channel is potentiometer adjustable from 0 to 100% of the output span. Terminals are provided to operate the test functions remotely for each channel. This also allows use as a remote manual override to provide a temporary fixed output if desired.
