I've already utilised the four wired outputs on the main board but need some additional outputs to connect to a centralised lighting system. The iON40 has 14 transistorised outputs, two of which are on the main board. However the other 12 appear to be on the plug by comms interface. There are two connectors for this, one with 12 pins and one with 4 pins. The 12 pin connector has labels for O/P 1-8 and the 4 pin connector has labels for O/P 10-13. I have a couple of queries on using theses outputs and hope someone can help.

Where is output 9 as it is not listed? There is a 0v pin on the main connector. If I utilise one of the outputs and the 0v pin will this provide me with the output I need? I can feed up to 24v through the input module of the lighting system without problem but it will also accept volt free contacts.

Any advice on utilising these plug by outputs would be appreciated.

I seem to recall reading that output 9 is deliberately missing...

 

I think this is because in some setups its hardwired as LF or something....

 

You will need transistorised relays for all these ops

Thanks for the reply. Interesting regarding output 9. Explains why its not labelled. However within the installer menu, you can stipulate what output 9 does.

Can I not simply connect the output directly to the lighting system input module?

It depends on the exact details of the lighting system; if they are just taking a logic signal rather than driving relays directly, probably...!

 

I think the thing about OP 9 was in the big master engineers manual (common to all Ions and about 200 pages) but can't be 100% sure...

Excellent thanks for the info.

Yes the lighting input module is just taking a logic input not driving relays. I'll try it and see.
