Description
Compact, economical & versatile. Laurel's BAR Series Bar
Graph Process Displays utilize a 1/8 DIN case like most digital
panel meters and fit in the same 1/8 DIN size panel cutout.
The bar graph is made of 30 LED elements, which can be red
or green. The display can be set up with a moving dot, for
example for position monitoring, or in the traditional accumulating
bar format, for example to indicate tank level. Please contact
Laurel Electronics for special scales for horizontally mounted
displays.
Transducer excitation standard. A 15 Vdc, 30 mA transducer
excitation output is standard and can eliminate the need for an
external power supply.
Optional Alarms. Two 5A, 250 Vac relay outputs are optional for
alarm or setpoint control. The alarms have a failsafe (de-energize
on trip) changeover output and an LED to show relay status. The
alarms are supplied in HI-LO format, but can easily be altered to
HI-HI or LO-LO. There's also a "pump-control" mode, where the
low alarm will latch, and will only reset when the input exceeds
the high alarm limit.
Designed for industrial environments. These bargraph
displays are highly immune to electromagnetic interference. The
front panel is environmentally sealed to IP54 (NEMA-12). Laurel's
Model IPC splashproof cover can extend protection to IP65
(NEMA-4). Signal connections are via detachable screw terminal
connectors.
