It is pretty hard to cover all the nastiness from ISO 16750-2-2010E, and especially so when replacing a blown fuse is not desirable.
How about this approach ?
The relay armature will take some 5-ish ms to operate, which is less than the 24.4V TVS clamp can take.
I think some extra resistance...
I have a circuit that
produces 2 pulses of (200mv)-(2v) when transitioning to On state
and
produces 2 pulses of (-200mv)-(-2v) when transitioning to Off state
I have would like to use these pulses in the simplest way possible to control a switch/relay/circuit
+12v on state
0 volt off state...
Hi, I have an IKEA wireless led power supply which outputs 24V DC / 54 mA current /10W max (model: ICPSHC24)
Challenge: I want to turn on a 220AC appliance when the led is on.
Unfortunately, the output current is too low to trigger a relay such as HF152FD, which would be the simplest and...
Hello there,
I'll start by saying I'm by no means an expert in electronic design, so please bear with me. Also my schematic and the datasheets I'm using will all be attached to this post.
I'm designing a circuit whereby the output of a 4017B IC is driving a relay via a BC337-25 BJT Transistor...
Hi, I'm new here, I've just started a project that has me building an electrical circuit for the first time and I don't really know what I'm doing! I'm hoping someone can answer a quick question.
I have a 12v electric motor (has two power levels, at 9A and 20A and it was suggested to go with a...
Hello,
I have a panel heater that stopped working. It's a large item, and a relatively basic electrical device. So rather than through it away, I'm going to try and fix it.
It has a relatively simply 2x1 inch component board in it.
What I have determined so far:
1. There is power reaching...
Can anybody advise me if the circuit attached will function as required.
The external timer supplies a 6 volt signal to the relay coil for between 3 & 9 seconds, this in turn drives the 12 volt motor for the 3 to 9 seconds & it also charges the 220uf capacitor.
At the end of the 3 to 9 seconds...
I need to Control I2C Relay device switching with 2 ESP8266, As I have to use wired connection and control the relay from 40 m distance from every ESP8266.
According to some suggestion, I should be using I2C extender but how much far we can use these extenders and is there any other way also...
I'm working on a project for school, it's basically a IR controlled fan with 9V DC. Basically you press any button on a tv remote and the IR sensor ( TSOP 1838) picks up the signal and outputs it to the fan and the fan spins. Problem with this is I have to continuously keep a button pressed on...
