These are the details of the new digital analogue input card from GHL. For those that want to add additional sensors that currently GHL do not supply. It's an open interface that you can DIY your own sensors to, as long as they fit the spec below:

The card has inputs for 2 analogue signals and 4 digital inputs which can be run with a common ground. All connections are isolated from the Profilux itself.

Requirements:
A free expansion slot
Firmware 4.07 or later, the firmware must be updated BEFORE installing the expansion card.

The voltages and signals can be accessed using the western plug or the enclosed SUB-D9 adaptor

The pin connections for the connections are as follows:
Pin1 Auxillary voltage +10v
Pin2 Digital input 1
Pin3 Digital input 2
Pin4 Digital input 3
Pin5 Digital input 4
Pin6 Analog input 1
Pin7 Analog input 2
Pin8 Ground GND

Pin 9 of the SUB-D9 plug is unassigned, Pin 1 at the Western socket is the lower one.

Technical Data:
Analog input, resistance ca. 20 kOhm, voltage range 0V to 10V
Digital Input, Input resistance ca. 100 kOhm, is to be switched to Ground GND
Auxillary voltage 10V: can be loaded with a max 10 mA

Obviously this will appeal to the DIY experts only, but opens the door to flow meters, leak detectors, door contacts, additional level sensors and fire/smoke detectors etc.

They will retail for around £64.99

flaming nora, what I have been waiting for!

pity im shutting down

still keeping the ghl so might give this a go for an optical LDR sensor.

just a quick quesiton also, how does the humidity interface for the reptile profilux work with the Plus 2 unit

Most of the above makes no sense to me Steve :laugh: Which probably means I shouldn't be using this card.

However, I've had 2 mini floods in 2 weeks (both my own fault) so the thought of a leak detector is very appealing :)

Any chance you (or anyone else) could post or pm me links to where some of the DIY sensor bits could be bought to make a leak detector? Or could a cut the cable off an Aquatronica leak detector and wire that up??

Cheers
Andy

There is a card and sensor available for the Plus II, it works just like any other sensor and you can control sockets based on it's reading.

Shame you are closing down :(

It was a bit like double dutch to me writing it out :laugh:

You could use the Aquatronica one, as I think it is a simple 2 wire device. But, I reckon you could make one from bits available at Maplin for less than £5. I'll try and get down to Maplin in Southampton this week and make one this weekend.

Give me a nudge if I forget, it is a bit hectic at the moment.

Oooooooh Maplin... only discovered the joys of that place about a year ago :)

Can you reserve one of these cards for me please? I assume I will need to put the order through one of the sponsor shops.

Thanks

I'll put one to one side for you Andy. I'll try and get it tested over the weekend for a leak detector and be in touch.
