The Model DNC-T2300-I/O module provides
several functions. It communicates with a
T2310 or T2320 Dust Collector Timer via the
RS232 port to form an Enhanced Timer sys
tem, and it communicates pertinent system
data to remote control/display devices via
the 2 wire Enhanced Timer Network. It also
incorporates three 4-20 mA current loop
inputs, three contact closure type inputs,
and one type J thermocouple input. In addi
tion, the I/O board provides 16K bytes of

The I/O board also has the capacity to
monitor the temperature of a type J thermo
couple in °F, with a range of 40°F to 700°F.

History Trending: The I/O board has the
capability to store data generated by the
Timer connected to its RS232 port as well
as data generated by the various sensing
devices connected to its inputs. Data histo
ry is subdivided into three categories: Short
Term History, Long Term History, and Alarm
History.
Short Term History is a time and date
stamped recording of the hourly averages of
the 4-20mA inputs, the Differential Pressure
from the Timer, the highest temperature
recorded, and the number of outputs that
were pulsed in that hour. This Short Term
History period is two weeks, after which
time the oldest 24 hours of recorded data
is averaged along with the highest recorded
temperature and the number of outputs that
were pulsed for that period and is stored in
Long term history.
The Long Term History period is one
year, after which time the oldest recorded
data is discarded to make room for new
data.
Alarm History is event driven, if any
alarm conditions occur, a time and date
stamped “snapshot” of all the system
parameters is recorded in a First-In-First­Out circular data buffer. This FIFO buffer
can store up to 212 alarm events and is not
time dependent.
In order to generate the Data History
Reports, a DNC-T2300-DSP Remote
Display Panel and a terminal device capable
of communicating standard ASCII via an
RS232 connection are required.

Caution:

1. Do not mount controls in high vibration areas with
out shock mounts.

2. Do not mount controls in areas of high dust or cor
rosive atmospheres without a protective enclosure.

3 Do not use a converter or inverter for the power
source.

4. Do not mount control in high transient voltage
areas without an isolation transformer.

-

5. Do not leave control box open.

6. Do not allow a local repair shop to repair the con
trols, as we employ some very sophisticated compo
nents that could be further damaged. For service, call
us directly: 800-323-2593.
