140AIO33000 Intrinsically Safe Analog Output Module
Overview The Quantum 140AIO33000 Intrinsically Safe Analog Output module controls and
monitors current loops in intrinsically safe applications. The module provides 8 dual-
ended output channels that are referenced over sense resistors to a single
Common. The output ranges are 4 ... 20 mA, 0 ... 20 mA, and 0 ... 25 mA. This
module detects broken wires on a per-channel basis indicates their location on the
front panel LEDs, and transmits the status to the PLC.
