TACHOMETRIC RELAY
Function Tachometric relay for general application.
Control and visualization of the rotation speed of motors shafts, turbines, etc., speed control on
conveyor belts, control the stop or break transmission chains or endless conveyor.
Operating mode Configurable by the user.
Each relay is assigned with its own operating mode.
Control of · Operating margin: 3..9999 rpm
rotation speed · The device does not process impulses with a duration less than 1/8 of the full cycle.
· Operability for max. and/or min. rotation speed. In each case, detection and release is to be adjusted.
· Operability for minimum rotation speed and engine starting. You can control the motor start by using
a push button between terminals Z1-Y4 (see example on page 2)
Timer · Associable to the detection and/or release of any relay and to the engine startup.
· Adjustable from 0.01 s .. 999.9 h
· Repeating precision ± 30 ppm
Resolution 1 rpm
Precision 1%
Time of detection 3 flanks of the input signal plus 5 ms of the relay reaction.
Types of rpm · Contact free potential: Y1 / Z1
input signal · Namur sensor: Y2 / Y3(+), link Y1/Z1
· PNP / NPN sensor: Y1 / Z1(-) / Z2(+12VCC). Maximum 10 mA
Type of input Contact free potential: Y4 / Z1
of the engine startup Only for the operability by minimum rotation speed in the engine startup.
Visualization to The read magnitud value is displayed by the status screen:
read value · ROTATION SPEED: rpm
Output relay From 1 to 3 independent relays, SPST NO. Three relays are supplied with the standard model.
Output 4-20 mA Assigned to the measure of the magnitude to be transmitted by the 4-20 mA current loop. It can coexist
with the relays.
Precision: 1% additional to the read value.
This kind of output is optional.
Connection diagram
PC communication It is possible establish different types of communication with a computer (see also the last page):
- By telephone connector that incorporates standard device and programming interface CPBZ.
- By a RS232 connection board (optional).
- By a RS2485 connection and the SBAZ converter (optional).

Control of maximum and minimum rotation speed
Settings available in the program 1 for relay R3. Parameters must be adapted to your installation.
td: Detection timer
tr: Release timer
Control of minimum rotation speed and engine startup
At a minimum control rotation speed, the relay SHA requires that the motor runs at its rated speed to get an effective control.
This application allows to assign a start timing during which inhibits the control of the rotational speed. It is essential to start the engine by
a push button connected to terminals Z1-Y4.
Settings available in program 1 for relay R1. Parameters must be adapted to your installation.

Scaling control of maximum rotation speed
In this application there are controlled three different points of maximum rotation speed, assigning each one to a different relay.
Settings available in the program 2 for relays R1, R2 and R3. Parameters must be adapted to your installation.

Value added
For a wide knowledgment of the options offered by the digital control relays, the own User’s Manual for each
model must be read. Although an issue is given with every purchased device, a copy can be donwloaded in our
web site (www.disibeint.com).
The digital control relays can be indistinctly programmed either with the buttons placed in the front of the housing
or with a personal computer.
Please refer at the end of this page to learn more about the PC programming alternative.
Status: They show the actual values of the magnitudes controlled by the relay.
User: Where the user can write a customized text to help to the relay identification.
Options: For accessing to the menus for the options selection.
Informatives for values: They show the information of the different set parameters.
Change of value: For modifying the values of the different values.
Screens menus: Group of screens related under the same concept and that can contain whichever type of the
screens previously described.
For an ease programming, into the menus only the options that can be set are the ones visible. The rest of the
options are not visible. This feature is interactive, ie., it is produced automatically according whether other
functions are activated or not.
The screens for changing the values contain the margins betwen such value can be adjusted. These margins can
depend of other options and this is because different margins could be displayed according to other previous
relations.
Provided by factory two programs with options and pre-configured settings for quick start-up team. In most
cases, these parameters should be tweaked to suit the characteristics of each installation. The user can create
your own program and store it on your computer.
The display remains backlihghted while it is accessed to the different screens. If any button is not pressed for
longer than 30 seconds, the light turns off.
In order to turn the light on, it is enough to press any button.
- Four languages available in each relay
- Graphic bar for the intuitive visualization of the displayed value
- Historical control of the maximum values obtained by the relay
- Screen’s refresh selectable between 1 and 8 times per second
- Possibility of locking the keyboard to avoid any undesired modification
- Complementary timing functions
