[Mesa 7I95] Eingang mit Taster was created by Muecke

Hallo miteinander,

ich möchte meine Taster an die Mesa 7i95 anschließen und bin etwas skeptisch daher wollte ich bei euch nachfragen was denn nun richtig ist.

Zitat Handbuch:

Code:

ALLGEMEINES - BESCHREIBUNG
...
24 isolierte Eingänge sind für allgemeine Steuerungszwecke vorgesehen, einschließlich Endschalter- und Bedienfeld-Eingänge. Die Eingänge arbeiten mit 4V bis 36V DC und können ein positives oder negatives Bezugspotential für Sourcing- oder Sinking-Eingangsanwendungen haben. 8 der isolierten Eingänge können zur Unterstützung von bis zu 4 Quadratur-MPGs verwendet werden.
....

ANSCHLÜSSE - TB6 ISOLIERTER EINGANGSSTECKER
Der Klemmenblock TB6 ist einer der isolierten E/A-Anschlüsse des 7I95. Er hat 16 Eingänge (0 bis 15)

TB6 PIN    E/A
1    EINGABE 0
2    EINGABE 1
3    IN COM 0,1


Was mich verunsichert ist die Beschreibung in "ALLGEMEINES - BESCHREIBUNG" denn da wird geschrieben das man die Eingänge von 4 bis 36V belasten kann?
Kann mir jemand Helfen wie man die anschließen muss?

Gruß Mücke
 


Hello everyone,

I want to connect my push buttons to the Mesa 7i95 and I am a bit skeptical therefore I wanted to ask you what is correct.

Quote manual:
[code]GENERAL - DESCRIPTION
...
24 isolated inputs are provided for general control purposes, including limit switch and control panel inputs. The inputs operate from 4V to 36V DC and can have a positive or negative reference potential for sourcing or sinking input applications. 8 of the isolated inputs can be used to support up to 4 quadrature MPGs.
....

CONNECTIONS - TB6 ISOLATED INPUT CONNECTOR
The TB6 terminal block is one of the isolated I/O connectors on the 7I95. It has 16 inputs (0 to 15)

TB6 PIN I/O
1 INPUT 0
2 INPUT 1
3 IN COM 0,1


What confuses me is the description in "GENERAL - DESCRIPTION" because it is written that the inputs can be loaded from 4 to 36V?
Can someone help me how to connect them?

Gruß Mücke

Sinking Inputs: (Two independent inputs shown)

COM 0/1 --> 4 to 36V COM (Power supply negative terminal)
+4 to +36V --> SWITCH0_COM --> SWITCH0_NC -> IN_0
+4 to +36V --> SWITCH1_COM --> SWITCH1_NC -> IN_1

Sourcing Inputs: (Two independent inputs shown)

+4 to +36V --> COM 0/1
IN_0 --> SWITCH0_COM --> SWITCH0_NC --> 4 to 36V COM (Power supply negative)
IN_1 --> SWITCH1_COM --> SWITCH1_NC --> 4 to 36V COM (Power supply negative)

There is no connection from the inputs to 5V, they are completely isolated

Ich habe versucht es Bildlich darzustellen, ich hoffe das ich es richtig verstanden habe.
I have tried to represent it pictorially, I hope that I have understood it correctly.

Sinking Inputs

Sourcing Inputs

Einen Widerstand muss ich nicht einbauen?
I do not need to install a resistor?

There is no connection from the inputs to 5V, they are completely isolated

?? Bedeutet das das ich ein neue Stromquelle nehmen muss?

You do not need a resistor

You can share the 5V supply (though its typically better to run mechnical switches on 12-24V)

Danke für dein Schnelle Rückmeldung!
Dann mache ich mich ans verkabeln.

Thanks for your quick feedback!
Then I'll get to work on the wiring.

Frage. Muss ich die GND (-) der Netzteile 5v und 12v miteinander verbinden ?

Ask. Do I have to connect the GND (-) of the 5v and 12v power supplies together?

Leider habe ich noch ein Frage, ich finde es im Handbuch nicht.

Wie viel mA ziehen die Eingänge?

Ich bin dabei das 12V Netzteil auszulegen:

6 x Taster (xx mA) = x,xx A
8 x NPN Sensor (200 mA) = 1,6 A

Gesamt 12V mit x,x A

Gruß Mücke

Unfortunately I have one more question, I can't find it in the manual.

How much mA do the inputs draw?

I am in the process of laying out the 12V power supply:

6 x push button (xx mA) = x,xx A
8 x NPN sensor (200 mA) = 1,6 A

Total 12V with x,x A

Nein, nein, nein !

That is the current the sensors can switch.
For our normal use they might use 20 to 30mA each, so a 2A power source should be more than enough for all the sensors and inputs.
20mA = 0.02 A

Oh dann habe ich da was Falsch interpretiert.
Danke für die Korrektur.

Wie viel Strom brauchen die Eingänge bei einem "Switch" Schalter ?
-- EN --
Oh, then I have misinterpreted something.
Thanks for the correction.

How much current do the inputs need for a "switch" switch ?6 x Taster (xx mA) = x,xx A
8 x NPN Sensor (30 mA) = 0,24 AGesamt 12V mit x,x A
