Panel Mount Tachometer
Model DT-5TG (VDC)
Features
Operational Precautions
! If the unit is used in a caustic environment, we
suggest you use a NEMA 4X enclosure.
! Keep unit free of vibration and shock.
! When installing unit, keep power and sensor wires
separate. Tie cable shield to terminal E (earth ground).
! After inserting wires, tighten terminal screws securely.
One of the most advanced on the market today, this
microprocessor-based panel tachometer not only mea-
sures rotational, linear and flow rate speeds, but can also
function as an elapsed time counter and ratio meter. By
choosing the desired input/output module(s), you can
design virtually any system imaginable.
! Mounts easily — no brackets or screws or any other
hardware needed.
! Tolerates a wide variation of voltages.
! Immune to electrically noisy environments.
! Programmable parameters and functions via front
panel membrane push-button switches.
! Accepts a variety of input and output modules
! No need to remember mathematical formulas.
! Highly accurate.
! Self-testing.

Specifications
Installation
Mounting Unit
Our 1/8 DIN case design eliminates the need for brackets
and screws for installation. With the tachometer in a level
position, insert it into the panel cutout. Gently push the
face of the unit until the front bezel locks into place. If the
tachometer case is loose, adjust the integral bracket with
the enclosed tool.
Removing unit
From the rear of the tachometer, alternately push the unit
from the left and right. This will free it for easy removal.

Sensors
Shimpo offers a large selection of sensors to meet you application needs. The chart below shows
the optimum sensor to use when designing your system. Please call us for more information.
Mode Selections
The DT-5TG has five modes of operation. Each mode
uses separate parameters for you to program:
Mode
Function
Application
1
Rate measurement
Measures rotational
(frequency input)
linear or flow rate speeds.
Factory set.
2
Elapsed time counter Times variable processes.
3
Rate measurement
For tachogenerator or
voltmeter. Requires input
module DOP-VF.
4
Ratio meter
Compares two signals in
either absolute or percent
ratio. Requires input
module DOP-RM.
5
Self test
Diagnostically tests LED
display, panel switches
and input circuitry.
1&2 DC input terminals.
3
Earth ground. Connect all cable shielding to this
terminal.
4
12 VDC 50mA max. This sensor power supply is for
any sensor that requires external power
5
Switch closure input. To be used with a relay or
solenoid. The input frequency must be less than 20Hz.
6
For use with open collector sensors. Connect the
sensor's signal output wire. No need for an external
pull-up resistor.
7

Mode 1: Rate Measurement
The DT-5TG can easily measure any rotational, linear or
flow rate speed. Each parameter function dictates the
necessary steps when preparing a system application.
Parameters 2 and 3 can be measured with a hand-held
digital tachometer (no need for arithmetic calculations).

Parameter 1:
Pulses Per Revolution from Sensor
Here's how to change the parameter from 1 to 60 pulses
per revolution ("p/r"):
1. Set unit to mode 1.
2. Press mode key.
3. Press shift key to select the
desired digit.
4. Press increment key 6 times.
5. Press shift key.
6. Press increment key 9 times.
Parameter 1 is now set for 60 p/r.
Parameter 2: Sensing RPM
To change the parameter from 50,000 to 1,000 rpm.
1. Press mode key
2. Press shift key
3. Press increment key five times.
4. Press shift key
5. Press increment key.
1.Apply any voltage between
9–35 VDC to terminals 1 and
2. When power is applied, the
display will show all zeroes. After
half a second, the display will
change to 00000.
2.Press mode and data set keys for
at least 5 seconds. A zero will
flash until 11111 appears on the
display.
3.Press the increment key to select
the mode you want. Mode
sequence will depend on input
module
4.Press mode key. You're now
ready to program the parameters
for the mode you have selected.
