Introduction
The DTM8000 Digital Meter is a powerful, microprocessor-based unit capable of being configured for
a number of todays demanding measurement needs. It can be quickly configured to operate as a digital
rate meter, timer, or feature-filled process counter. It also offers up to two alarm outputs which can be
adjusted for a number of trigger conditions. Its durable 1/8DIN aluminum housing can be easily mounted
in a panel or control cabinet. Flexibility makes the DTM8000 ideal for applications such as:
Pay-out and Take-up Limit Monitors
Conveyor Oven Tunnel-Time Monitors
Rotating Machinery Tachometers
Material Measurement Meters
General Features
- Microprocessor-based design combines responsiveness and accuracy in one package
- Selectable display update rate
- Capable of measuring shaft speeds lower than 1 RPM @ 1 pulse per revolution
- Large 4 digit, ½ LED display
- Field programmable via front-panel keypad
- Lexan membrane and gasket (which are included) meet NEMA 4X standards when used with NEMA
4X enclosures
- Internal program-enable jumper selectively prevents tampering with units configuration
- Universal power supply accepts line voltages inputs from 85-265VAC @ 50-60Hz without switches
or jumpers. The unit automatically adjusts as needed.
- Non-volatile memory stores adjustable parameters even when power has been removed
- Compatible with a variety of signal input types including: Hall-Effect Pickups, Photoelectric, TTL, etc.
Note: Open collector devices must be capable of sinking 3mA.
- Wide operating ambient temperature range of -10C to 45C (14F to 113F)
- Self-contained power supply for external sensor, limited to 5V @ 50mA
- Up to 2 programmable alarm outputs with Form C contacts rated to 250VAC @ 5A
- Multiple auto-ranging features allow the user to view display values from 0.001 to 99,990 in any user-
defined unit. (GPH, MPH, RPM, etc.)
- Multiple operating modes including:
Rate Mode Displays in rate unit such as RPM, Gallons per Second, etc.
Time Mode Displays in time unit such as HH:MM, MM:SS, SS:TT, or other unit
Counter Modes Displays resettable and reloadable counter value which can optionally
increment or decrement for each input pulse. Quadrature inputs can automatically
be translated to up/down counts for bidirectional applications
