Description The ArmorStart Distributed Motor Controllers are integrated, pre-
engineered, starters with Bulletin 280/281 for full-voltage and
reversing applications and Bulletin 284 for variable frequency AC
drives applications. The ArmorStart offers a robust IP67/NEMA Type
4 enclosure design, which is suitable for water wash down
environments.
The modular “plug and play” design offers simplicity in wiring the
installation. The quick disconnects for the I/O, communications, and
motor connections reduce the wiring time and eliminate wiring errors.
The ArmorStart offers, as standard, four DC inputs and two relay
outputs, to be used with sensors and actuators respectively, for
monitoring and controlling the application process. The ArmorStart’s
LED status indication and built-in diagnostics capabilities allow ease

protection per UL508 and IEC 60947. The ArmorStart is rated for
local-disconnect service by incorporating the Bulletin 140 Motor
Protector as the local-disconnect, eliminating the need for additional
components. The ArmorStart Distributed Motor Controllers are
suitable for group motor installations.
