With high brightness 25mm LED digits, the 550-2A Digital Indicator offers solutions for applications where long-range readability is important. This panel meter a provides a 4½ digit scaleable display of an analogue signal in engineering units. User configurable scaling to ranges within +19999 to -19999, input signal selection and universal mains power enable spares/stock holding to be kept to a minimum. |

Inputs
The input may be user configured to accept most standard voltage and milliamp process signals. Input types are selected by an internal switch and link combination (non-standard inputs are available to order).
Scaling
Scaling in engineering units may be set to any portion of the display range i.e. within the range -19999 to +19999 (minimum span - 2000 counts). The required readouts at full scale and zero are set by internal switches and trimming controls.
Decimal points
The decimal point position is switch selectable.
Reversed reading
Reversed reading can be configured. e.g. with 4mA input the display can be set to read ‘15000’ and with 20mA input, to read ‘0’.
Controlling the display externally
The following features are provided at the rear of the instrument.
Peak reading
When activated only the highest input signal reading is displayed. Subsequent measurements are compared with the previous result. If the new value is larger than the previous peak value, the new value is displayed. If the new value is less than the previous peak value, the display remains unchanged - activated by a volt-free contact closure..
Hold reading
Holds the readout at the current value whilst the activation signal is maintained - activated by a volt-free contact closure..
Display brightness
Adjustable via rear panel control
Display blanking
Switches off the readout - activated by a volt-free contact closure.
Custom legends
Custom made legends, e.g. depicting engineering units or process description, can be supplied at no extra cost or can be made and fitted by user.
Splash resistant front panel
A flexible transparent rubber hood offering front of panel protection up to IP65 is available as an option.
