A deluxe bargraph indicator with enhanced control capabilities. Flexible and highly configurable for display of electrical signals and process parameters. Combines the precision of a digital readout with a vivid proportional display. Includes numerous computation functions, SCADA options and an extensive input module selection.

Features
  • Single & multiple channel inputs
  • Adjustable bargraph span & zero position
  • Bar & digital display can be set to different channels
  • Datalogging and PID control functions
  • Cross channel math capability
  • Six smart setpoints with 8 selectable functions
  • Front panel setpoint status indicators
  • Up to 6 relay outputs for control and alarms
  • Single or dual analog retransmit option
  • Wide power supply range (AC & DC)
  • 8 level brightness control from the front panel
  • Sensor excitation to power 4-20mA transmitters, bridge type sensors or other transducers
  • Programmable input filter and display resolution
  • Digital communications and PC setup software
The Premo BarGraph line is based on a high resolution A/D converter and 32 bit CPU with floating point math capability. This high performance measurement and computation platform provides unique capabilities in a switchboard instrument. In addition to displaying and retransmitting a single channel signal, the Premo meter can display two channels, perform cross channel math, log data and control processes.

Setpoint Control
Up to six setpoints can be configured for control and alarm functions. Each relay may be programmed to activate above or below a setpoint, operate with hysteresis or delay, latch, track another setpoint, perform one shot, pulse and repeat timer functions or On/Off control. For processes with overshoot or undershoot, the PID mode on SP1 & SP2 provides stable control.

Datalogging
Premo BarGraph Meters will log data in either linear (writes until full) or cyclic (overwrites oldest data) FIFO modes. A reading can be triggered from the program button, a digital input, time or an alarm condition. Optional memory allows storage of up to 4000 readings in non-volatile EEPROM. The optional real time clock can be used to initiate readings and time stamp the data. A lithium battery provides clock back-up in the event of power loss. The clock will also activate a setpoint or control function at a preset time.

Display
The bar can display 1 of 4 inputs or 1 of 2 totalizers. It can be setup for min/max mode, linear/log scaling, offset zero, center zero, suppressed zero and/or peak/valley display. The source for the six digit selected. Decimal position & display brightness are set from the front panel.
