but with different housings, outputs and interfaces.
All models are equipped with 4 programmable presets and 4 fast-switching transistor outputs
as well as a serial RS232 interface.
SD models provide this basic configuration only.
SA models provide an additional high-speed analogue output

All further properties of the models are fully identical. The range of available models also
includes units with relay outputs and front thumbwheel switches.
The following table explains the details of type designation and the possible options:

2. Introduction
Speed meters of series SD, SA and SR have been designed to close a gap with multiple speed
measuring applications, which cannot be accomplished by normal industrial tachometers.
A continual demand for increasing production speeds and higher precision at the same time
results in counting frequencies exceeding the conventional frequency range.
Particularly with fast running machines it is most important to also get fast response of the
switching outputs or the analogue output.
Many applications require to evaluate the signals of two incremental measuring systems, and
to compare the results with respect to the sum or the difference or the ratio of the two speeds.
The latter is e.g. required to indicate the diameter of a winding roll by sensing the line speed
and the roll rpm.
Other applications with food processing or process technology need to record the speed in a
reciprocal way (i.e. baking or processing time calculated from the actual speed)
And still there exist applications where the use of traditional thumbwheel switches offers real
advantages compared to keypad and menu operations.
These are some of the reasons why the new indicator series SD / SA / SR have been designed.
This manual at first provides all basic instructions for operation of the
counter models presented in the previous chapter
For operation of relay outputs and thumbwheel switches (if applicable)
please observe the supplementary instructions given in the appendix
For easy PC setup and PC communication with SD and SA counters,
please use our “OS32” operator software (free of charge, download from
our homepage www.motrona.com
Where you like to have free serial access to the unit by PLC or IPC or by a
remote operator terminal, please observe the serial protocol details
described in our separate manual “Serpro”
Subsequently the manual uses the expression SD340 as a replacement for
all available models. However, statements are fully valid for the other
models too, except where especially remarked.

3.1. Power Supply
The SD340 counter accepts both, a 17 – 40 volts DC power or a 24 volts AC power (+/-10%)
for supply via terminals 17 and 1. The current consumption depends on the level of the input
voltage and some internal conditions; therefore it can vary in a range from 100 – 200 mA
(aux. currents taken from the unit for encoder supply not included).
3.2. Auxiliary Outputs for Encoder Supply
Terminals 2 and 18 provide an auxiliary output with approx. +5.2 volts DC (300 mA totally).
Terminals 3 and 19 provide an auxiliary output with approx. +24 volts DC (240 mA totally)
3.3. Impulse Inputs for Incremental Encoders
All input characteristics of the impulse inputs can be set by the parameter menu, for each of
the encoders separately. Depending on the application the unit can accept single channel
information (input A only without direction signal) or dual channel signals (A = step and B =
direction) or quadrature information (A / B, 90°). The following settings are possible:
Symmetric input (differential A, /A, B, /B) according to RS422 standard
TTL inputs at a level of 3.0 to 5 volts (differential, with inverted signal)
TTL inputs at a level of 3.0 to 5 volts (single-ended) *)
HTL signals at a 10 – 30 volts level
(alternatively differential with inverted signals A, /A, B, /B, or single-ended A, B only)
Impulses from photocells or proximity switches etc. providing a HTL level (10 – 30 volts)
Proximity switches according to NAMUR (2-wire) standard
(may need additional remote resistor)
*) requires special settings of the threshold parameters, see “Special parameters F08”
All encoder input lines are internally terminated by pull-down resistors ( 8,5 kΩ).
Where encoders with pure NPN outputs are used, corresponding pull-up resistors must be
available inside the encoder or externally to ensure proper function (1 kΩ... 3,3 kΩ).
3.4. Control Inputs Cont.1 – Cont.4
These inputs can be configured for various remote functions as described under 6.2.4.
All control inputs require HTL level. They can be individually set to either NPN (switch to -) or
PNP (switch to +) characteristics. For applications where edge-triggered action is needed, the
menu allows to set the active edge (rising or falling). Control inputs also accept signals with
Namur (2-wire) standard.
For reliable operation the minimum pulse width on the control inputs should be 50 µsec.

SD34002g_e.doc / Sep-13 Page 10 / 60
3.5. Switching Outputs K1 – K4
SD340 provides four presets and outputs with programmable switching characteristics.
K1 – K4 are fast-switching and short-circuit-proof transistor outputs with a switching capability
of 5 – 30 volts / 350 mA each. The switching voltage of the outputs must be applied remotely
to the Com+ input (terminal 29)
3.6. Serial Interface
The serial RS232/RS485 interfaces can be used for the following purposes:
Set-up of the unit by PC (if desirable), by means of the OS32 PC software
Change of parameters during operation
Readout of actual counter or other values by PLC or PC
The figure below explains how to connect the SD340 unit and a PC using the standard Sub-D-9
serial connector, and how to connect the RS485 terminals to a PLC.
Details about serial communication are shown in chapter 9.

Where both, RS232 and RS485 interface are in use, you can communicate by the one or

3.7. Fast Analogue Output (SA models only)
An analogue output is available with all SA models, providing a voltage output of +/- 10 volts
(Load = 2 mA), and a current output of 0 – 20 mA or 4 – 20 mA (load = 0 – 270 Ohms). All output
characteristics like beginning of conversion range, output swing etc. are freely programmable
via menu. The response time of the analogue output depends on the mode of measuring and
the sampling times used. The analogue resolution is 14 bits.
Please note that extensive serial communication with the unit may temporary increase the
analogue response time.
