Functional Characteristics:
The board organizes its sixteen input channels into four isolated groups of four channels each, providing effective protection against common-mode voltages. A precision 250 Ω resistor ensures accurate current-to-voltage conversion for standard 4–20 mA loop-powered transmitters. The 120 ms scan rate delivers adequate update speeds for most process monitoring and control applications. Robust filtering attenuates high-frequency noise from variable speed drives and heavy switching loads.
Installation Requirements:
The board occupies a single slot in Experion PKS and TDC 3000 chassis. The removable screw terminal block accepts 28 to 12 AWG field wires. LED indicators on the faceplate display channel activity and overall board operational status.
Usage Precautions:
The IP20 protection rating requires enclosure mounting. The 1,500 V AC isolation between each group of four channels and the system bus prevents ground potential differences from affecting measurement integrity in large distributed installations.
