The PTC900 series has been discontinued. Please see the PTC-20 Series as a possible alternative or contact our sales department.
The PTC900 timer and PTC901
clock/timer offer many features and
performance capabilities that suit a
wide range of industrial applications.
Both can function as an elapsed
timer or preset timer, while the
PTC901 also offers real-time clock
with date capability. The Plug-in
option cards allow the user to
configure the meter for the present
application, while providing easy
upgrades for future needs. Both
models can function as an elapsedtime
indicator. By using 2 separate
signal inputs and 23 selectable
timer ranges, the meters can be
programmed to meet most any
timing application. With the addition
of a plug-in setpoint output card,
they can easily become a dual or
quad output preset timer. The
PTC901 can also operate as a realtime
clock with the real-time clock
card already installed.
The meters are capable of
displaying time in 12- or 24-hour
time formats. The 12-hour format
can be displayed in hours and
minutes, with or without an am/pm
indication or in hours, minutes, and
seconds. The 24-hour format can be
displayed in hours and minutes or in
hours, minutes, and seconds.
The PTC901 also has a calendar
display in which the day, month
and/or year can be displayed. The
meter will recognize leap years, and
can automatically adjust for Daylight
Savings time. If the application calls
simultaneously for a preset timer
and a real-time clock, the PTC901
can handle this requirement as well.
A battery-backed real-time clock
plug-in card is provided with the
PTC901. This card, which includes
a lithium coin-cell battery, will
maintain the time and date when
main power is removed.
The meters accept inputs from a
variety of sources, including switch
contacts and outputs from CMOS or
TTL circuits. The input can be
configured to trigger on the edge or
level of the incoming pulse. Internal
jumpers are available for selecting
sinking inputs (active-low) or
sourcing inputs (active-high). The
front panel keys and three user
inputs are programmable to perform
various meter functions. The meters
can have up to 4 setpoint outputs,
determined by the optional plug-in
cards. The setpoint plug-in cards
provide dual form “C” relays (5A),
quad form “A” relays (3A) or either
quad-sinking or quad-sourcing open
collector logic outputs. The outputs
can be assigned to the timer,
counter, RTC date, and RTC
time. The outputs can also be
independently configured to suit
a variety of control and alarm
requirements.
Plug-in cards can also provide serial
communications. These include
RS232, RS485 and MODBUS.
Display values, setpoint alarm
values and setpoint states can be
controlled through serial
communications. Once the meters
have been initially configured, the
parameter list may be locked out
from further modification entirely, or
the setpoint, timer start/stop values,
counter start/stop values, RTC time
“set”, and display intensity can be
made accessible. Lockouts are
activated through a security code or
user input.

Comes with complete operator’s manual.
Note: Adding option cards—meters can be fitted with up to 2 optional plug-in cards, however, only 1 card from each function type can be installed at a time. The function types include setpoint alarms and communications. The cards can be installed initially or at a later date. Each optional plug-in card is shipped with installation and programming instructions.
