2. Introduction
The GIA 20 EB / PK is a microprocessor controlled displaying, monitoring
and controlling device.
The device is supporting one universal interface for the connection of:
- Standard transmitter signals (0-20mA, 4-20mA, 0-50mV, 0-1V,
0-2V and 0-10V )
- Resistance sensors
- Frequency (TTL and switching contact)
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 beneath 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.
Furthermore the device supports one EASBus-interface so that the device can communicate with a host
computer via an interface converter and makes the device to a full functions EASBus-module.
When leaving our factory the GIA20EB / PK has been subjected to various inspection tests and is completely
calibrated.
Before the GIA20EB / PK can be used, it has to be configured for the customer’s applica-
tion.
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 con-
figuration.
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 +Us, high-side push-button, ...).
When configuring the device with a NPN switching output, a pull-up-resistor (~11kΩreferring 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 (~11kΩreferring 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-up-
voltage 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.
Connection of a transducer (with separate power supply) Connection of a transducer (without separate power supply)

Hint: Rv2 = 600Ω, Rv1= 1.8kΩ(with power supply voltage = 12V) or 4.2kΩ(with power supply voltage = 24V), device config.: Sens = TTL
(Rv1is a current limiting resistor and may be shorted if necessary. It should never exceed the mentioned value.)
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 in chapter 3.3.6.
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 out-
put, 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: “+Us-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 pre-
sent). The output transistor opens or the push-pull output changes from +Us to –Us when an alarm con-
dition 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 voltage 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, protec-
tive measures to limit these peaks have to be taken.
When switching large capacitive loads a series resistor for current limitation needed, because 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 -Us connection of the external power supply unit.
When doing this, you get rid off ground displacement.

3.5. Common wiring of several devices
Inputs and outputs are not electrically isolated. When interconnecting several devices you have to make sure
that there is no potential displacement.
Make sure to observe the following points:
- When several devices are connected to the same power supply unit it is highly recommended to isolate the
sensors, measuring transducers etc.
- When the sensors, measuring transducers etc. are electrically connected, and you can’t manage to isolate
them, you should use separate electrically isolated power supply units for each devices. Please note, that
an electric connection may also be created via the medium to be measured (e.g. pH-electrodes and con-
ductivity-electrodes in fluids).
