BL-B51D40,24x96mm Bargraph Meters

51 segment bargraph with a 4-digit LED digital display for monitoring, measurement and control applications


  • The bargraph can display, full scale, any desired portion of the digital reading.
  • Bargraph center zero function.
  • Four programmable setpoints.
  • Setpoint 1 has delay-on-make and delay-on-break plus a special “pump on pump off” mode that creates a Hysteresis Band between SP1 and SP2.
  • Relay activation can selected to occur above or below (Lo) each setpoint.
  • Digital display blanking.
  • Decimal point setting.
  • Four-level brightness control of the bargraph digital display.


The BL-B51D40 is a 51 segment bargraph with a 4-digit LED digital display for monitoring, measurement and control applications mounted in a 24x96mm case. As a member of the leopard family, the BL-B51D40 can easily be configured simply choosing from over 40 different Plug-in I-Series Input Signal Conditioners.
