I/O Modules
module status indicators. Some output modules and modules with Intrinsic Safety
interfaces have indication for the channel error status.
The S800 I/O modules 24/48 V d.c. have channels isolated in groups. Each group
has a field power status input to indicate presence of field power. The loss of field
power is indicated on Warning LED, module status set to warning and channel
status set to error.
The 120/250 V a.c. or d.c. modules have individually isolated channels. 
The input module can be configured to monitor field power status.
S800L I/O modules 24 V d.c. have one isolated group with 16 channels, used
together with TU805 enable 2-and 3-wires connections. The input modules can be
configured to monitor field power status. Loss of field power will set module status
to warning and channel status to error.
Outputs do not need external inductive load suppression components.
