Hi HTA,
Thanks for the reply.
Yeah, it was those tables (Tables 1 and Table 2) that have thrown me a bit - if both device's input were logic capable why mention PWM, I don't understand why have two identical devices doing exactly the same and having the same spec. (I'm picturing pulses being...
Hi,
Admin - Please move if posted in wrong section.
I'm intending to build a quick test bench to test a change in a hardware design and count the corresponding action. (The originating piece of kit uses a battery fed 3v DC motor which needs to be regularly reversed)
I don't want to use a PWM...
Hi Klaus, thanks for the reply
My appologies, yes you are correct - I just automatically assumed automotove to mean 12Vdc and continuous upto 14.4Vdc forgetting there are other values around.
As a follow up question, could these be used (guessing different values) in place of the normal...
Hello All,
I'm just starting to get the bits together for a simple automotive (marine) relay > fusebox > load project, and started to think about the specifics mainly around contact supression.
Due to lengh of run I need to remotely switch on the 'ignition' fuses via a relay. My maximum load...
Hi,
Backgtround-
I need to power a RF and logic switching board from a 12Vdc (automotive based) supply which feeds a water pump motor. The position of my intended project will be approx 2m away and the other side of a metal bulkhead even so I intend to use a FM based modules.
Question-
I...
Hi Tony,
Thanks for the reply.
Yes, I did consider the environmental conditions these range of relays has a fully sealed option (as does the G5V-2 alternative).
These have Silver/Gold Bifurcated contacts
Whats thrown me the curve ball is that statement from the datasheet. I can use...
Thanks for the reply
The application I'm working on is for voltage sensing in a split charging system so I don't want any possibility of the contacts getting 'dirty' and not being 'cleaned' by a current flowing, so again I ask the question is 8hrs considered a longtime for these relays...
Hi,
Just looking at the datasheet for the Omron G6A range of signal relays and read the following statement
"Long-term Continuously ON Contacts
Using the Relay in a circuit where the Relay will be ON continuously
for long periods (without switching) can lead to unstable contacts
because the...
Thanks for the reply
No, the LED doesn't need a regulated supply. Before I posted here I did a quick net search and found info saying that the Zener need a minimum load (over and above the normal series current limiting resistor) in order to operate so the LED / resistor combo which just there...
Hi all,
I need to supply two voltage for sensing purposes via a DP relay, for a third party device.
I know nothing about the load (current) characteristics or input impedance of this device, but the input voltage is approx 11Vdc to 15.2Vdc
Now (assuming the correctly chosen resistor values)...
Hello All,
Some pointers if you please its been years since I dabbled with electronics (bit rusty!!) and I just don't know enough about motor control electronics / good practice to allow me to complete a little project I'm working on.
I have a 12vDC 'sensor' water pump in which the electronic...
