INTENDED USER
System engineers and technicians should read this manual
before installing and operating the ASO module. A module
SHOULD NOT
be put into operation until this instruction is
read and understood. You can refer to the Table of Contents to
find specific information after the module is operating.
MODULE DESCRIPTION
The ASO consists of a single printed circuit board (PCB) that
occupies one slot in a Module Mounting Unit (MMU).
Dipswitches on the PCB configure each of the analog outputs.
Two captive screws on the faceplate secure the module to the
MMU. A front panel LED indicates the module status.
The slave module has three connection points for external sig-
nals and power (P1, P2 and P3). P1 connects to logic power that
drives the module circuits (refer to Table
5-2
). P2 connects it to
the slave expander bus to communicate with a Multi-Function
Processor (MFP) module (refer to Table
5-3
). The analog signals
are output through connector P3 using a cable connected to a
Termination Unit (TU) or Termination Module (TM) (refer to
Table
5-4
). The terminal blocks (physical connection points) for
field wiring are on the TU/TM.
FEATURES
The modular design of the ASO, as with all INFI 90 modules,
allows for flexibility when you are creating a process manage-
ment strategy. It outputs fourteen analog signals that an MFP
uses to control a process.
The ASO analog outputs are signals of 1 to 5 VDC or 4 to 20
mA. Individual switches configure the mode (current or voltage)
for each output. This capability allows the INFI 90 system to
match the process requirements.
The front panel LED provides a visual indication of the module
status to aid in system test and diagnosis. You can remove or
install an ASO module without powering the system down.
