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.
