A basic relay module has eight relays and can be extended by a further eight re-
lays through a pluggable extension relay module.
Redundant triggering of the relays is via two 8-bit microcontrollers. Free param-
eterization of the relays with the aid of the software ConfigPro meets all indi-
vidual requirements:
•
AND-to-OR Logic Operation
•
Open and Closed Circuit Operation
•
Grouping
•
Voting
•
Time-delay and Slow Release
•
Relay Function for Buzzers
•
Relay Reproduction
Up to eight relay modules with a total of 128 relays can be integrated in the sys-
tem. The redundant, optodecoupled RS 485 bus enables spatial separation (up to
1km) of the modules and control unit. An address of 1-8 is allocted to each
module via rotary switch.
Open circuit:
The relays are activated as soon as the respective status is recognized, ie the re-
lays pick up.
Closed circuit:
The relays are activated during undisturbed operation, ie the relays have picked
up and will be deactivated in case of alarm, ie the relays will be released.
