5.0 TERMINAL MODULE
5.1 The Terminal Module is made to be rail-mounted and is the point of interface
between the field sensor wiring and the DE-3000+ control system. A removable
dual terminal strip is used for the connection of the system to the equipment
mounted discrete sensors which may consist of up to 30 inputs, where any of
the 30 can be used for either a normally-open, normally-closed switch, or analog
inputs including K- or J-type thermocouples. These are listed as channels 01–
30 for the 691171-1 terminal board. They accept industry-standard transducer
signals in the range of 0-5 VDC. Connections from the Terminal Module to the
Display Module are made using the 693115-x series Cable Assembly.
5.2
The DE-3000+ is designed to operate with industry-standard voltage or current-
amplified output transducers in the range of 0 to 5Vdc or 0 to 25mA. Four se-
ries of transducers are available from Altronic: pressure transducers 691201-x,
691204-x and temperature transducers 691202/203-300, 691212/213-450.
5.3 Another terminal board assembly may be added to increase the inputs from 30
to either 45 or 60 inputs. Use cable 693133-1 to connect the two boards. The
691175-2 provides an additional 15 inputs, 4 digital outputs, 2 analog outputs
and an extra speed (pickup) input. The 691171-2 provides an additional 30
inputs, 8 digital outputs, 2 analog outputs, and an extra speed (pickup) input.
5.4 PRESSURE TRANSDUCERS
The pressure transducers, Altronic P/N 691201-x and P/N 691204-x, are pack-
aged in a rugged sealed case with a NPT pressure port, a corrosion resistant
media cavity, and a Packard Electric Metri-Pack connector. The ranges available
are 0-100, 300, 500, 1000, 2000, and 5000 PSIG for the 691201-x series
and 0-50,100, 300, 500 PSIA for the 691204-x series, all of which have an
overload rating of 1.5 times full scale without damage. The three wires from the
transducer are: +5 volt excitation, +0.5 to 4.5 volt output, and minus return.
These three wires connect directly to the back of the Terminal Module using
cable assembly P/N 693008-x.
5.5 DIFFERENTIAL MEASUREMENTS
Differential pressures or temperatures may be measured by using two consecu-
tive channels. The transducers used to measure differential values must be of
the exact same type and range. The first channel of the pair will display the
basic parameter it is monitoring and the second channel of the pair will display
the numeric difference in engineering units of its value subtracted from the first
channel’s value. Setpoints for each channel monitor the displayed value of that
channel. The second channel setpoints monitor the differential value.
5.6 TEMPERATURE TRANSDUCER
The temperature transducers, Altronic P/N 691202-300, 691203-300 with a tem-
perature measurement range of +5 to 300°F and the 691212-450, 691213-450
with a temperature range of -40 to +450°F are packaged in a sealed, stainless steel
housing with a 5/8"-18 UNF threaded body, and a Packard Electric Metri-Pack
connector. During configuration the standard calibration for the 691202/203-300
sensor is selected as dEG1 and the standard calibration for the 691212/213-450 is
selected by choosing dEG2. The three wires from the transducer are: +5 volt excita-
tion, temperature output voltage, and minus return. These wires connect directly to
the Terminal Module using cable assembly P/N 693008-x.
5.7 THERMOCOUPLE INPUTS
The Terminal Modules can accept industry-standard type J or K thermocouples
on inputs 01–60. Automatic cold junction compensation is built-in. The units
can be configured to °F or °C. Both a high and low setpoint is associated with
each channel. The monitor can read type J thermocouples between -76°F and
+1382°F (-60°C and +750°C) and type K thermocouples between -76°F and
+1472°F (-60°C and +800°C).
5.8 N/O and N/C INPUTS
The inputs can also accept standard normally-open and normally- closed con-
tacts. For normally-open input, place the wire between the corresponding in-
puts. Ground the connection to cause a fault. Similarly, for normally-open, wire
the sensor in a normally-closed connection and open it to cause a fault.
