ELK MM443 Specsheet

Magic Module™ Programmable Controller

ELK-MM443

The MM443 is a programmable logic controller (PLC)
with four analog or digital inputs and four relay outputs.
It may be used as a stand alone controller in a vast
array of applications from timers, door controllers,
simple process controllers, multiple zone security
controls, etc. or as a networked controller with up to 31
other modules connected on a common RS-485 data
bus. The Magic Module supports transmitting and
receiving commands from two way X-10® Power Line
Carrier Devices. Also optional interfaces are available
for reading Temperature, Clock/Calendar, Wiegand
Proximity devices, Dallas iButton™ identification
devices, and can be interfaced to Caddx NX Security
Controls.

The Magic Module is programmed by a personal
computer. The program is stored into re­programmable Electrically Erasable Programmable
Read Only Memory (EEProm memory). The ELK
Starter Kit (ELK-MK400) or Programming Kit (ELK­MK485) contains components and software needed to
program the Magic Module™.
