The 8900 Series offers a low cost TC (thermocouple) and
RTD signal conditioning solution for applications that require
a 0-10V output signal. All models isolate and linearize. The
thermocouple conditioners also have cold junction
compensation. The 8900 Series also offers a variety of analog
to analog isolators, i.e., 0 - 50mV to 0 - 10V or 4 - 20mA to 0
- 10V etc. The isolation is three way, input to output, input to
power and output to power. All models are powered by
24VDC.
All modules are housed in a plastic case with a built in DIN
rail mounting foot. The case dimensions are 4.3"L x 0.89"W
x 2.9"H. All connections are made to easily accessible screw
clamp terminals.
