DESCRIPTION
SOLID STATE DIGITAL
METER MODULES
Applications
These models offer a variety of functions, sizes,
voltages and customizable options to fit most
applications. Ideal for OEMs, contract manu-
facturers, and panel makers for monitoring
equipment usage, scheduling maintenance,
warranty validation, rental/leasing use and
more. Used extensively in industrial, agricultural,
military & specialty vehicles, as well as applica-
tions such as: vending machines, medical &
office equipment, fuel pumps, and consumer
products.
Features
• Selection - hour meters, counters, odometers,
maintenance monitors and more.
• Solid State Circuitry - no moving parts to wear
out. Silent operation and years of rugged &
reliable operation.
• Precision - faster response, more precise and
easier to read than electromechanical meters.
Crisp, clean readouts - high-contrast
5 & 7mm LCD displays.

high quality components to minimize space.
• AC/DC Configurations - wide range of oper-
ating voltages & noise protection.
• OEM Compatibility - an unparalleled selec-
tion of power compatibility, design configura-
tions and functionality for OEM custom
designs, panel makers and contract manu-
facturers.

meter/timer activation and display modes.
• Backlighting - available on all models (see
model coding chart or consult factory).
• Power-up LCD Function Test - displays all 8’s
for 1 sec at power-up (models 700-703
only).
• EEPROM memory – nonvolatile, retention of
data for as much as 25 yrs.+ without power.

Notes: 1. All modules are supplied with critical components exposed. If the module is being used in an environment other
than specified, the user must take precautions to package the module to provide adequate protection.
2. For proper mechanical support, all module pins should be soldered to the PC-board.
3. To prevent heat damage to components, module face should be 10-20mm minimum away from PC-board when
flow soldered.
