Types of Input/Output Processors (IOPs)
There are thirteen types of Input/Output Processor (IOP) card assemblies. Some IOP card types interface
with more than one type of Field Termination Assembly (FTA). The functional types of IOPs are:
 High Level Analog Input (HLAI)
 Low Level Analog Input (LLAI)
 Low Level Analog Multiplexer (LLMux)
 Remote Hardened Low Level Analog Multiplexer (RHMUX)
 Digital Input (DI)
 Analog Output (AO)
 Digital Output (DO)
 Smart Transmitter Interface (STI)
 Smart Transmitter Interface Multivariable (STIM)
 Pulse Input (PI)
 Digital Input Sequence of Events (DISOE)
 Serial Device Interface (SDI)
 Serial Interface (SI)
ATTENTION
Fieldbus is not supported by the TPS Network.
AO and DO IOPs
Some of the functional types of IOPs support only certain associated Field Termination Assemblies
(FTAs) models because the number of channels (Points) differ. Examples are the Analog Output (8 and
16 channels) and Digital Output (16 and 32 channels) IOPs.
Redundant IOPs
IOPs can be connected in a redundant configuration with both IOPs connected by separate cables to the
same FTA. Some models of the following types of IOPs support redundancy.
 Smart Transmitter Interface (STI)
 High Level Analog Input (HLAI)
 Digital Input (DI)
 Digital Output (DO)
