What is it?
« on: March 30, 2013, 06:22:45 PM »

can anyone please tell me what this is? I've been doing model boats for over 40 years and have never come across one before. If any one does know could they tell me how and what it's wired to? Thanks, Martin

I would say that it's a dual switch !

Does the IC state ZN409 ?

I agree with tica, whatever is on the IC :-))  Plug it into the receiver and you have two on/off switches controlled by one channel.

definitely not a dangle obtuse ojamaflip a thingy or a speed controller! One of the boxes says.....

KG1P-F
RES. LOAD
10A 110VAC OR 24V DC
5A 220VAC
COIL DC 6V.

]Hope that helps.

The two boxes are relays.

would it be a 6V output powered by the receiver?

Flip it around and take a picture from the other side of the part and we will easily be able to tell you how to use this switch.

BTW: The 6V is the requride voltage to pull the relay on.

The chip zn409 was used in speed controllers like electronise before the chip went out of production and the speedos changed, there is also a variable pot for adjustment so might be as circlip says a low wattage speed control.

For what its worth regards sub.

Dual relay switcher. One relay closes stick forward one closes stick back.


You could wire aux functions or a bow thruster.

Definitely a switcher there's no heavy components to variably switch motor current, useful for a single speed bow thruster or two heavy load (10 amp) items. You connect a + supply to the common terminal and your load + to the normally open contact for basic on off control of your load. The load neg is connected directly to supply neg.


For a thruster or reversible motor



the 30 terminal is common, 87 is NO and 87a is NC, tor the purpose of this exercise you can ignore the 85 and 86 terminal, they are taken care of by the board. (EDIT I Got NO and NC reversed :embarrassed: )

wrong thread.... %%
 >>:-( .
 
But I did notice a lack of fly back diodes..
The pot is probably to adjust the sensitivity.
The rest of the bits just help translate PWM into Voltage to crack the relays.

Before three phase motors and ESCs, one step up from "Bobs Boards" was the speed controller that used a pulsed relay for speed control. The chip varied the on/off ratio of the relay(s) like a mechanical Triac.   
 
   409 was one of the PWM chips fitted to many "Solid State" servos and replaced lots of discrete components

No question but that it's a dual relay switch. The legend on the copper side of the PCB actually identifies the Common, Normally Closed and Normally Open contacts of the Left and Right relays. I imagine the pot might control the switching point i.e. how far you have to push the stick before the relay is triggered. The only unanswered questions are
1. What is the current rating of the relays (often inscribed on the face of the relay itself)? and
2. Is the switch latching or non-latching i.e. does it stay closed when you let go of the stick? Easy enough to find out by trying it.
I'm curious to know who made it, as it looks like something which has been neatly DIY-etched onto plain copper-clad laminated paper board  rather than "professionally" produced on epoxy-cloth board. Could be from a magazine article. I think the ZN409CE chip went extinct around 1998, although I see they are still traded at around twenty eight quid EACH on Fleabay.......... I have a small supply which I am saving as part of my pension pot  8)

it said 10A at 24V DC (relays will have a different rating for dc and AC)

O, yeah - missed that bit!

Mind you, I've just spent half an hour looking for 100 x LEDs which I was convinced I'd thrown away by mistake, only to find them sitting in a drawer of a storage cabinet which I'd labelled up and where I'd put them only on Thursday............... What???  :o

Why is it I can remember stuff from 40 years ago and yet I forget things I did this week?
