"Plug and Play" Expandable Input and Output Cards
The PPR-1800 is equipped with 6 rear expansion slots, which work
with the following input/output cards:
- Analog Input Cards Different cards are available for 3,
2 or 1 channel analog
input. Each input is isolated from the others to reduce
noise and to ensure a stable measurement. The analog input
is configured by dip switches and a jumper for each channel
on the card before plugging it into a rear expansion slot.
Using all 6 expansion slots and six 3-channel Analog Input
Cards, up to 18
channels can be recorded.
- Digital/Relay Output Card Each card contains 6 alarm
relays. The contacts are rated at 5 Amp/240V. Each alarm
relay can be programmed to close on any channel variable.
- Digital Input Card Each card includes 6 channels of
digital inputs. They can be used for recording events or
triggering the recorder to start. External devices such as
relay/contact closure, transistor pull down or TTL logic can
be connected.
- Analog Current or Voltage Output Cards Each card
includes 3 channels of
Current (4-20mA, 0-20mA) or Voltage (0-5, 1-5, 0-10 Vdc).
They can be used to retransmit data to other instrumentation
such as PLCs.
Communication and Software
Observer I software is supplied with the PPR-1800 and is used for
transferring data manually between the recorder and a personal
computer using the CompactFlash™ Memory Card. It has Configuration
and Historical Viewer sections.
The optional Observer II software is used when the PPR-1800 is
hardwired into an Ethernet network, or used independently with an
RS232 / 422 / 485 interface. It has a Realtime Viewer in addition to
the Configuration, and Historical Viewer sections.
After receiving the data in the Historical Viewer section, the
Observer I or II software allows the user to export the data in MS
Excel® format.
CompactFlash Memory Card Storage Media
The external memory of choice in an industrial environment
with
its inherent vibration and dirt is the CompactFlash™ Memory
Card. The CF memory cards, with no moving parts, are
advantageous over floppy drives, which are susceptible to
failure in the industrial environment.
A 32MB capacity CF memory card is provided with the recorder.
The memory port is located in the front of the unit behind the
access door. This can be upgraded to 128MB, 256MB or 1GB CF card
at a nominal fee. Alternatively, the user can purchase them
locally. To ensure compatibility, Tempco recommends only SanDisk
or Transcend brands.
Each data record uses 2 bytes of CF card memory. The following
formula is provided to calculate how long a CF memory card could
last before it is full, assuming 24-hour operation.
Firmware Option for Mathematics,
Counter, Totalizer
and FDA 21 CER Part II Compliance
Mathematical functions such as addition, subtraction, sine or
cosine, etc. can be applied to an analog channel or channels and
stored, or displayed on a “Math” defined channel.
The Counter provides up to 6 counters with 2 actions/jobs per
counter. Name, description, unit, preset value and type can be
configured.
The Totalizer provides up to 6 totalizers with 2 actions/jobs
per totalizer. Name, description, unit, period, preset value and
type can be configured.
FDA 21 CER Part 11 compliance software is included with the Math
Functions option. This software routine follows the rules for
electronic historical documentation as established by the
Federal Department of Agriculture (FDA). It allows the user to
establish levels of security and authority for Administrators,
Supervisors, and Operators. An audit trail function records the
user, time, and type of work done.
