Supported Applications
The Omega DPF20 Series is a 6-digit, 1/8 DIN panel meter designed for frequency, rate, total, or period counting applications. The series supports multiple operational modes including impulse counter, ratemeter, and periodometer functions.
The unit accepts various sensor types to accommodate diverse industrial signal sources:
- Mechanical contact
- Namur
- NPN (2-wire and 3-wire)
- PNP (2-wire and 3-wire)
- Push-pull
- TTL/CMOS pick-up
- Inductive sensors (<30 Vp AC)
Operating Conditions & Performance
The DPF20 features a 6-digit display with 14 mm digit height and offers configurable measurement ranges based on the selected mode:
- Counting frequency up to 250 KHz in 'FAST' mode.
- Maximum frequency up to 500 KHz in 'SLOW' mode.
- Minimum frequency down to 0.001 Hz (1 mHz) in 'SLOW' mode.
- Display range from -199,999 to 999,999 with decimal point positioning.
The meter provides a front protection rating of IP65 and includes configurable trigger levels. Excitation voltage is adjustable from 5 Vdc to 18 Vdc depending on the sensor configuration. The unit supports multipliers and dividers ranging from 1 to 99,999.
Configuration Options
The DPF20 Series offers extensive configurability through a modular model number structure: DPF20 - <Power> - <Option 1> - <Option 2> - <Option 3> - <Others>.
Power Supply Options
- HV: 85-265 Vac/dc
- Lv: 11/60 Vac, 24 Vac, 48 Vac
Outputs and Communication Interfaces
The series supports the following output and communication options (configurable in Option slots):- R1: 1 relay (up to 3 relays available)
- T1: 1 transistor output
- SSR: 1 SSR drive control
- AO: Isolated analog output
- RTU: Modbus RTU communication
- S4: RS-485 ASCII
- S2: RS-232
Additional Features and Options
- NBT: No buttons (sealed front)
- GN: Green LED display
- Password protection for configuration menu access.
- Retention memory to recover data after power loss.
- Double setpoint alarms with activation/deactivation delays, hysteresis, and inverted relays.
Key Product Differences
The DPF20 Series distinguishes itself through its configurable architecture. The base model supports 'SLOW' mode for slow frequencies and 'FAST' mode for fast counting. Electrical connections utilize plug-in screw terminals. Specific variants differ by power supply selection (HV or LV) and the combination of output modules installed in Option 1, Option 2, and Option 3 slots.Available configurations include combinations such as DPF20-HV-R1-AO-SSR-NBT, allowing for simultaneous relay control, analog signaling, SSR drive, and a sealed front panel. The series also supports display filters (recursive), memory functions (max., min., cycles), and configurable reset options via the front, rear, or linked to alarm activation.
