DESCRIPTION

The BLD457 digital indicator is equipped with one measurement input with user selected range 0-20 mA or 4-20 mA, 0-10VDC and a standard resistor protection circuit. Additionally the BLD457 allows user to select a conversion characteristic of several kinds: linear, square,

square root and user defined - max. 20 points lenght. Users have the possibility of an 8-step adjustment of display brightness. The device features a 4-button keyboard for programming basic settings, which for greater security is located under the front cover. In order to make setting changes without unsealing the casing, remote control can be included by means of an (optional) infrared remote control unit. The keyboard on this remote control unit is the same as the device's keyboard.
