We need two types (operating voltage).
- 1.5V (without power reverse function)
- 12V (with power reverse function)
1.5V must have a very low power consumption (lower uA) as it is supplied by 1.5V Alkaline Battery
12V is supplied by mains power plug-in power supply (230V > 12V), needs power reverse function, but power consumption is not so relevant.
1. Can you make output as open collector?
2. Can you make Connectors like the one attached to this email? (we need to replace this -attached pics- timer with new one, 1.5V)
12V can have standard connectors.
