THE SCOTT SAFETY 7400 PLUS AND 7400 PLUS
CONTROLLERS are designed to provide simultaneous
display and alarm functions for up to four monitored
variables. A graphic LCD displays monitored data as bar
graphs and engineering units. Three adjustable alarm
levels are provided per channel. Relay outputs allow
control of beacons, horns and other alarm events.
The controllers are easy to configure and are user friendly.
Measurement ranges in engineering units, adjustable
alarm set-points, optional serial interfaces and
many other features offer flexibility to meet most
demanding applications.

The controllers utilise NEMA 4X rated enclosures and
are CSA certified to CSA C22.2 No. 152 for combustible
detection and Class I, Division 2, Groups A, B, C and D
hazardous locations. An optional RS-485 MODBUS® slave
port allows up to 128 controllers to be multidropped
onto a single data highway for interrogation by another
MODBUS master.
