GE 8202-HO-IS 8-channel Intrinsically Safe Analog Output, 4-20 mA with Hart
Benefits
• More accurate event sequencing
All logged events are time stamped using
1/8 ms resolution for 1/4 ms accuracy. The
Controller uses Network Time Protocol (NTP)
to assure time stamp accuracy between
modules across the network. When using
NTP, all controllers are synchronized across
the network to ± 3 ms, resulting in very
accurate event sequencing
• Identify problems quickly
Each SOE input has a unique line fault
detection feature that detects whether
there is a short circuit or open circuit on
each input. Problems are identified immediately for correction, saving considerable
maintenance time.
• Simplifies field wiring
Field circuits are module-powered, eliminating the need to “daisy chain” power
supply wiring at field terminals. Field
circuits are powered with a minimum of
wiring and termination effort.
• Locate SOE modules in the process
Like the rest of the control platform, SOE
modules can be located in your process,
next to your field devices in order to record
events locally on a more reliable and
timely basis.
• Easy integration with other applications
Events from multiple modules and controllers can be stored in a single SOE Event
Logger providing an easy interface to
other applications.
32 Discrete Channels
The 8127-DI-SE has 32 discrete input channels and each channel can be configured as
either an SOE input or a standard discrete
input. SOE input signals can also be used
as standard discrete inputs as part of any
control strategy. Each module can buffer

up to 512 events. Events are communicated
to the controller, which uses Network Time
Protocol (NTP) to accurately convert the
module’s time stamp data to real time. The
SOE Event Logger, which constantly polls
the controller for new events (typically every
2 seconds), collects each time-stamped
event. After recording the events, the Event
Logger sends and acknowledgement to the
controller, which then clears the event from
its memory. The controller retains all events
until all active Event Loggers acknowledge
them. Multiple Event Loggers can be used for
redundant event recording and will always
have consistent time stamps since all events
are time stamped by the controller.
Events are displayed by the SOE data Retrieval
Client. Following data retrieval, the user can
select to email the SOE data, Print it or Save
it to a CSV file. The user can easily create a
custom report, selecting the columns to be
viewed and printed.
