Alternative zu Terxon Relaiskarte für 5EUR

[Nobbi75]

N'abend,

habe mich bei dem Preis für die Relaiskarte für die Terxon schon an den Kopf gefasst...

Sehe gerade bei Ebay für 5EUR inkl. Versand eine 12V Relaiskarte, die auf den ersten Blick genau das gleiche macht, oder???

Bei 5EUR kann man nicht viel falsch machen...aber so von den Eckdaten sieht das für mich sauber aus.

Habe für meinen Raspberry Pi (Volkszähler) schon öfter Bauteile in Fernost bestellt - Preis Leistung war bisher immer perfekt!

Was meint Ihr?

Danke

Norman

Hier die Beschreibung:

Description :
1. The module uses genuine quality relay , normally open interfaces Maximum load : AC 250V/10A, DC 30V/10A;

2. Using SMD OPTOCOUPLER isolation , driving ability , stable performance ; trigger current 5mA;

3. The module voltage is 5V, 9,12 V, 24V are available ;

4. Each way module can be set high or low triggered by jumper ;

5. Fault-tolerant design , even if the control line is broken , the relay will not operate ;

6. The power indicator ( green ) , 4 relay status indicator ( red )

7. Interface design humane, all interfaces can be connected directly via terminal wiring leads , very convenient

8. Module size : 73mm * 50mm * 18.5mm ( L * W * H )

9. Has four mounting bolts holes , hole 3.1mm, 67mm * 44.5mm pitch



Interface :

1. DC +: positive power supply ( voltage required by the relay , there 5V.9V.12V and 24V choice )

2. DC-: negative power connection

3. IN1-IN4: each way based on the settings , can be high or low to control the corresponding relay



outputs :

a 12- line interface, the interface can be directly connected to all leads , user-friendly

1. NO1 - NO4: normally open relay interfaces , relay before the vacant after the pull shorted with COM

2. COM1 - COM4 Common Interface Relays

3. NC1 - NC4: normally closed relay interface relay shorted with COM ago , after the pull- vacant



High and low trigger selection :

1.S1-S4 in order to relay a way -4 road high and low trigger selection ;

2.Com with low short circuit , triggering the corresponding relay is low , while the high end of the short com high trigger
