Maximum power input for IN1,IN2 on FGBS-321?

[Guest bozman]

Hi,

 

What is the maximum power input for the FGBS-321  on IN1,IN2 ports?

 

I'm looking on 300 mA from a device is that to much for IN1 or IN2 on FGBS-321.

 

Didn't find anything in the manual.

 

 

 

Regards Boz

You put a switch between IN1 and GND. IN1 has a pullup resistor so the UBS can detect switch open - switch closed. The current through IN1 is minimal. What's the 300 mA for? Power supply? In that case: 50 mA / 12 Volt will do. After telling this I still got the feeling that I didn't understand your question... What are you trying to do?

Ok i'm wondering if 300mA is to much for signal into IN1? What is the maximum for the input? 10A/1A/100mA?

Thanks for sharing.

You don't inject any current into IN1. You connect the contact of a relay or a push button between IN1 and GND. There is no power source involved. The current that runs through the contact is low. I've measured it some time ago but I don't remember it exactly, but it is a few mA. Why do you want to run "10A/1A/100mA" through IN1 (to use your own words)? If you tell me what you want to do with it, I may be able to answer your question... I have one Universal Binary Sensor available for testing.

Ok, I understand, what I want to do is to connect a UBS to a DSC larm output panel, one output is on 50 mA and the other is on 300 mA when active. That why I wondered if it could to much, but reading your post I have to trough relay?

Alarm systems (both modules and controllers) usually already use relays as output. This is a hint: if the contacts are marked NC (normally closed) or NO (normally open) then they probably are relay outputs and compatible with IN1. Is it possible to post the technical documentation? That would eliminate all doubt. Otherwise you'll have to find out by measuring the output.
