3-8900.401-6 Four inputs, two passive 4 to 20 mA outputs
3-8900.401-7 Four inputs, two active 4 to 20 mA outputs
3-8900.401-8 Four inputs, two 0 to 5/10 VDC outputs
3-8900.401-9 Six inputs, no outputs
3-8900.401-10 Six inputs, two passive 4 to 20 mA outputs
3-8900.401-11 Six inputs, two active 4 to 20 mA outputs
3-8900.401-12 Six inputs, two 0 to 5/10 VDC outputs
• These modules determine the maximum number of sensor input channels
available for the instrument. The 8900 will detect all connected sensors
at startup and assign channels up to the maximum available on the I/O
Module.
• Optional analog outputs are contained on the I/O Module, and will always
be identifi ed as Outputs 1 & 2 in the 8900 menus. Any and all analog
outputs are freely assignable to any channel. All analog outputs available
from the 8900 are isolated.
• Voltage outputs are independently software selectable for operation from 0
to 5 or 0 to 10 VDC.

CAUTION
4.2 Power Module, required; install one (1)
Mfr. Part No. Description
3-8900.402-1 85 to 264 VAC, 50/60 Hz
3-8900.402-2 12 to 24 VDC ±10%
• Each 8900 Base Unit may be powered with either AC or DC voltage, but not both
simultaneously (no "uninterruptible" power option).
• The AC Power Module is universal; no jumper selection is required.
