According to Absolute Process Instruments (API; Libertyville, IL) its new high accuracy APD 8000 is the company’s most versatile signal conditioner yet. The unit accepts a thermocouple, RTD, thermistor, DC or potentiometer input, and converts it to an optically isolated DC voltage or current output. It can be set up and calibrated using onboard switches and pushbuttons without the need for a computer or special programmer.
The APD 8000 is perfect for applications where one device needs to cover any number of I/O types. Microprocessor-based linearization and a low noise 18-bit analog output offer ±0.1% accuracy. Exclusive features include an output test function and a variable-brightness Loop-Tracker LED to indicate the input signal level. Also standard are sink/source output capability, 1200 VRMS full optical isolation, fast shipping and a lifetime warranty. Versions are available for temperature, thermocouple, RTD, thermistor or DC input only.
