Each AOM has an address Dip switch for address selection of the AOM in the 32
System. Up to two AOM's may be used in each SYSTEM 32.
7.5 PULSE INPUT MODULE -- A32-PIM
The PIM counts up to 32 pulse inputs at maximum pulse rates of 1kHz with 50%
duty cycle pulses. The A32-PIM can only be used in systems with an expanded
PROCESSOR I/O MODULE [A32-PIOM-EX].
7.6 POWER SUPPLY----PART NO. A32-PS
The power required by the SYSTEM 32 is 5 vdc at 5 amps. Each module of the
SYSTEM 32 has a DC to DC converter for isolation and to provide the regulated
voltages used. These voltages are typically +5vdc and +15vdc.
Since each module includes isolation and regulation, nearly any 5vdc supply can be
used. The SYSTEM 32 can be run from battery power since only a single voltage
is required.
The A32-PS includes a standard SYSTEM 32 front panel, and wiring to the
SYSTEM 32 backplane. The power supply is normally mounted in one module
slot. For systems that require all the slots for other modules, the power supply can
be mounted externally.
The rating of the A32-PS is 120 vac input with 5 vdc at 7 amp output. The power
supply has an adjustment for the 5 vdc.
For a spare supply, option A32-PSWOFP [Power Supply With Out Front Panel] is
available.
7.7 OPERATOR STATION -- A32-OS
The OPERATOR STATION is used to view the measured input value or Process
Variable (PV) for any loop of the SYSTEM 32. The OPERATOR STATION can
also be used to change the Setpoint (SP) of a loop at a remote location from the
computer.
The OPERATOR STATION is a panel mount 1/8 DIN LED readout instrument
utilizing the communication line from the computer to the 32 System. The
OPERATOR STATION front panel contains the function keys for the display
selection and setpoint changing.
