The LDB Series of large displays offer a wide range of measurement, alarm, and display capabilities for all types of industrial and commercial applications. Data can be seen at distances of up to 50 m (160') and by a large audience.

OMEGA LDB Series Large Displays for Industrial Applications
These displays can provide control, alarms, and/or retransmission of measured data with field-installable options for relay or transistor outputs, SSR controls, analog retransmission signals, and communications in Modbus RTU, RS485 or RS232 ASCII protocols. All circuits are isolated for reliable performance and protection.

The LDB series features a full NEMA 4 (IP65) metallic housing, designed to be panel mounted, wall mounted or suspended. The front keypad allows for easy configuration, and an optional remote keypad is also available.

The front lens is made from anti-reflective tinted methacrylate, which provides a sharp and clear reading at long distances. Additionally, 5 levels of LED brightness allow for adjustments to suit most environments.

I am using a process meter to display the distance of a laser. I am thinking there is some scaling somewhere I cannot find so can someone show me which conif. settings to use? Thanks.

Asked by: L810
Thank you for the inquiry. Please forward this request to TEMP@OMEGA.COM. Best regards OMEGA

Hello, I can't find the user manual for the large display measurement type - Process Current/Voltage, the M5678 user manual contains a description of only models with digital inputs. Is signal scaling possible for a display with analog input? Thanks.

Asked by: Igor
Hi Igor, Thank you for the inquiry. The process meter version manual is linked here; Yes, scaling can be applied to the displayed value. Our apologies for difficulty. Best regards OMEGA
