Open Access Mega
I’ve been working on a larger, SMT version of the Open Access controller for the last 2 weeks.
The prototype boards have just been ordered, and I’ll post the design as soon as I get one built and tested.
Features include:
- 8x5A Form-C relays
- 16xSupervised alarm zones
- 2xWiegand reader ports with full pinout (8 pins/ea)
- RS-485 on-board
- All new switching PSU
