Relay Expansion
CCTV, alarm systems, HVAC, lighting or storage lockers? MASI
has developed a cost-effective solution to meet your multiple
output security needs. With the use of MASI’s relay
expansion board, you are now able to provide higher levels
of security, improved integration, along with ease of programming
using Modern Witness 2000, a true Windows software product.

Up to four-relay expansion boards can be connected on the
RS-485 databus, thus allowing full programming of 128 relays
from each controller. The databus allows remote installation
of relay expansion boards near elevator controllers and other
peripheral devices. The result is simplistic installation
and a dramatic reduction in wire distance with improved communications
between the relays and the controller. Any single relay can
be individually programmed to specific authorization levels
and time schedules.
MASI’s relay expansion boards provide solutions to your
current requirements as well as address any future expansion
requirements
