2. Introduction
The DI15 is a microprocessor controlled displaying, monitoring and controlling
device.
It is equipped with one multi-function input for the connection of:
- Standard transmitter signals (0 ... 20mA, 4 ... 20mA, 0 ... 50mV, 0 ... 1V,
0 ... 2V and 0 ... 10V )
- RTDs (Pt100 and Pt1000),
- Thermocouples (type K, J, N, T and S)
- Frequency (TTL and switching contact)
As well as rotation measuring, counting, etc. ...
The device features two switching outputs, which can be configured as
2-point-controller, 3-point-controller, 2-point-controller with min./max. alarm,
common or individual min./max. alarm.
The state of the switching outputs is displayed with two LED’s below the front 4-digit LED-display.
The left LED displays the state of the 1st output, the right LED displays the state of the 2nd output.
Hint: In order to avoid undefined input states and unwanted or wrong switching processes, we sug-
gest to connect the device’s switching outputs after you have configured the device properly.

3.3.6. Connecting a frequency- or rotation-signal
When measuring frequency or rotation three different input signals can be selected in the device’s configuration.
There is the possibility of connecting an active signal (= TTL, ...), a passive sensor-signal with NPN
(= NPN-output, push-button, relay, ...) or PNP (= a PNP output switching to +Ub, high-side push-button, ...).
When configuring the device with a NPN switching output, a pull-up-resistor (~11k referring to +3.3V) is
connected internally. So when you use a device with NPN output you don‘t need to connect a resistor
externally.
When configuring the device with a PNP switching output, a pull-down resistor (~11k referring to GND)
is connected internally. So when you use a device with PNP output you don‘t need a resistor externally.
It may be that your measuring-signal source needs the connection of an external resistor e.g. the pull-upvoltage of 3.3V is not enough for the signal source, or you want to measure in the top level frequency
range. In this case the input signal has to be treated like an active signal and you have to configure the device as „TTL“.
Hint: when connecting the device you have to take care not to exceed the limits of the input
voltage respective the input current of the frequency-input.

3.3.7. Connecting a counter signal
When configuring the device you can select 3 different input signal modes similar to the connection of
frequency- and rotation-signals. The connection of a sensor-signal for a counter-signal is the same used
for the frequency- and rotation-signal.
Please use the wiring diagram given below.
There is the possibility to reset the counter. When connecting contact 8 with GND (e.g. contact 7) the
counter will be reset. You can do this manually (e.g. with the help of a push-button) or automatically
(with one switching output of the device).
Hint: When connecting the device, take care not to exceed the limits of the input-voltage or the input-
current of the frequency input.

3.4. Connecting switching outputs
The device features two switching outputs, with three different operating modes for each switching output, which are:
Low-Side: “GND-switching“ NPN output (open-collector)
The switching output is connected to the negative rail of the supply voltage (connection 3
or 5) when active (switching output on).
High-Side: “+Ub-switching“ PNP output (open-collector)
The switching output is connected to the positive rail of the supply voltage (connection 4)
when active (switching output on).
Push-Pull: The switching output is connected to the negative rail of the supply voltage (connection 3
or 5) when inactive. When the switching output is active, it’s connected to the positive rail
of the supply voltage (connection 4).
In case of configuring one output as an alarm output, the output will be active in idle state (no alarm present). The output transistor switches or the push-pull output changes from +Uv to –Uv when an alarm
condition occurred.
Hint: In order to avoid unwanted or wrong switching processes, we suggest to connect the
device’s switching outputs after you have configured the device’s switching outputs
properly.
Please take care that you must not exceed the limits of the vo ltage and of the maximum current
of the switching outputs (not even for a short period of time). Please take extreme care when
switching inductive loads (like coils or relays, etc.) because of their high voltage peaks, protective measures to limit these peaks have to be taken.
When switching larg e ca pacitive loads a se ries resist or for curren t limit atio n needed , bec ause of
the high turn-on-current of high capacitive loads. The same applies to incandescent lamps,
whose turn-on-current is also quite high due to their low cold resistance.

Hints:
Connections 3 and 5 are internally electrically connected.
When switching higher currents (> 50 mA) , the –Uv connec-
tion should not be attatched to the device (connection 3) but to
the –Uv connection of the external power supply unit.
When doing this, you get rid off ground displacement.
