Description Compact, economical & versatile. Laurel's BAR Series Bargraph 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 bargraph is constituted 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.
For process signals. The BAR Series Displays accept all popular process signals, such as 4-20 mA, 0-20 mA, 0-10 mA, 1-5 V, 0-10 V, and -5 to +5 V (to be requested at time of ordering). A bargraph process meter can be combined with a digital process meter to provide both graphical and numerical representations of the same signal. Transducer excitation standard. A 15 Vdc, 30 mA transducer excitation output is standard and can eliminate the need for an expensive 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. |
