The Oliver IGD universal pellistor
drive PCB is designed to take input
from a standard pellistor and give
either a linear 4-20mA current source
output or digital RS485 addressable
output.
Status LED’s are provided to indicate
mode of operation and correct
operation through the internal fault
detection systems.
Please note that a known calibration
gas will be required to calibrate the
unit.
