Analog Output Modules
4-20 mA Output Module IOP320
This module, featuring eight 4-20 mA output channels, receives power from
the 24V-system supply via the backplane edge connector. Loop power is also
available to the module via the backplane and is individually fused 24V for
each channel.
LED Indication
A green LED, labeled Active at the bottom of the module front panel, is on
when system power is present and the module is communicating with the
DPU. This LED blinks on and off when the module is not being scanned by
the DPU. A second green LED provides the status of the loop power fuse
disconnect.
