The ELK-MM443 is a Programmable controller with 4 relays, 4 inputs, X10 (needs interface), RS485 and iButton.
If you had a chance to design your own PLC type device what would you change?
Internally it uses a PIC16C76-04. Myself I'd use a flash chip, possibly an 18F series.
Would you add a RTC? How about a standard RS232 port as well as a RS485. More relays? More inputs? Optoisolation? ZigBee? Memory? Display? Keypad?

• Four analog or digital inputs
• Four relay outputs (2 relay outputs may be jumper programmed for transistor open collector outputs)
• 16,384 program bytes using SIMPLE programming language
• 4 general purpose Counters, range 0 to 255 counts
• 4 general purpose Timers, range 1/10 second to over 255 hours
• Networked to optional PC and up to 31 ELK-MM443’s through a RS-485 data bus.
• X-10® Power Line Carrier Interface. PL513, PSC04 (Transmit Only), or TW523, PSC05 (Two Way).
• Analog transmission MM443 to MM443 and Preset Dim Commands.
• Dallas iButton™ TouchKey Reader with optional ELK-MA100 or ELK-MA290 interface
• Programs the ELK-MM220 (two inputs, two relay outputs)
• Emulates ELK-MM220 for code development
• Program stored in non-volatile EEProm memory
