Highlights, Models Micro-P & Micro-C

  • The state of the art in programmable digital panel meters, counters, timers, and serially driven remote displays.
  • Wide choice of signal conditioners for analog and digital inputs.
  • Wide choice of outputs for control, alarm and data communications.
  • Exceptional performance for 5-digit digital panel meters:
    High speed (60 readings / sec) with 99.99% accuracy for DC signals.
  • Exceptional performance for 6-digit digital counters and rate meters:
    High speed (up to 25 readings / sec) with 6-digit resolution for frequency or rate.
  • Exceptional performance for serially-driven remote displays:
    with RS485, up to 31 remotes addressable on on data line, each with optional local analog and setpoint outputs.
  • All DPM and counter ranges user-selectable and factory calibrated.
  • Universal 95-240 Vac 10% power supply standard, low voltage AC or DC power supply optional.
  • Easy setup and scaling.
  • Available in 1/8 DIN case panel meter size with bright red or green 0.56" high LED digits.
  • Also available in large-digit versions for long-distance viewing: 1" digits (Mighty-1), 5" digits (Mighty-5).
  • Two-year warranty.


Micro Series digital panel meters, counters, timers and serially-driven remote displays are an exceptional value by providing high performance at minimum cost, as made possible by state-of-the-art circuit design and firmware. Modular design and a wide range of plug-in options allow the Micro Series to be configured for a wide range of applications from simple measurement to control and communications as part of a data network.

Micro Series base models, as featured in this web page, provide 0.56" high red or green LED digits, and are housed in a standard 1/8 DIN size panel-mount case (48 x 96 mm panel cutout). All power and signal connections are via push-in screw-clamp connectors.

Large-Digit models using the same signal conditioning boards, I/O boards, and firmware, are also available for viewing across a plant floor or outdoor yard: 1" digits (Mighty-1) and 5" digits (Mighty-5). The Mighty-5 features sunlight-readable, ultra-bright LED digits, plus a NEMA-4X housing which can be installed outdoors in any weather.

The minimum hardware modules of a Micro Series instrument or remote display are a power supply, display subsystem, signal conditioner board, and microcomputer board. Different microcomputers boards are used depending on the application (DPM or counter, standard or extended). Three slots are provided to plug in an optional alarm / setpoint controller board, an analog output board, and a communications board. In combination with firmware and user-programmable selections, these modules provide a rich set of solutions for industrial measurement, display, and control applications:

Micro Series 5-Digit Analog Meters by Application:

Micro Series 6-Digit Counters & Timers by Application:
  • Frequency & Rate MeterTwo independent scalable pulse-input channels from 0 Hz to 1 MHz to display frequency, rate, RPM, or flow rate.
  • Up/Down Totalizer (pulse input)Two independent scalable pulse-input channels count up or down to a preset at rates up to 1 MHz. Ideal for turbine flow meters. Scaled rate and total in same instrument.
  • A+B, A-B, A*B, A/B, A/B-1 Draw MeterArithmetic functions (+, -, /, x) on dual channels A & B. For example, add or subtract rates from two flow meters for combined scaled flow or volume. Display ratio of flow rates, RPM of rollers, or speed of moving belts.
  • Batch Controller (pulse input)A low-cost controller with up to three relays for repetitive fill operations.
  • Batch Controller (analog input)Same capabilities as pulse-input batch controller, but for 0-1 mA, 4-20 mA or 0-10 V process signals.
  • Digital StopwatchTime single-events from 1 s to 99 hours with a timing resolution to 0.2 s, or accumulate multiple events to 999,999 hours.
  • Time Interval MeterTime periodic events from 1 s to 199.99 s over a programmed gate time up to 199.99 s with a timing resolution to 0.2 s.
  • Phase Angle Meter20 updates per second for low frequencies, such as AC line frequency. A resolution of 1, 0.1 or 0.01 is user-selectable.
  • Duty Cycle MeterDisplays ON or OFF period as a percentage of total period over a programmed gate time from 10 ms to 199.99 s.
  • Quadrature Meter:  Scalable position or rate from quadrature shaft encoder signals.
Micro Series 6-Digit Serially-Driven Remote Displays:
  • Serially Driven 6-Digit Remote Display: RS232 interface for point-to-point communications, or RS485 for up to 31 addressable displays on same data line. Each remote can provide independent setpoint control and an analog output tied to the display.
