DPF20 Frequency, rate, total or period counter Instruction Manual
1. Panel meter DPF20
Counter, ratemeter and periodmeter, 96 x 48 mm (1/8 DIN)
Panel meter 96 x 48 mm (1/8 DIN) and 6 digits with 14 mm digit height,
congurable with 5 impulse counter modes (see secon 1.2), 2 rate-
meter modes (see secon 1.3) and a 1 periodmeter mode (see secon
1.4).
Highly congurable, accepts all types of sensors (NPN, PNP, push-
pull, Namur, inducve, pick-up, mechanical, TTL, CMOS, ...) including
quadrature signals (single and bidireconal encoder signals).
Reading from 999999 to -199999 with decimal point, scalable read-
ing with congurable mulplier factor (1 to 999999) and congurable
divider factor (1 to 999999). Includes internal pull-up and pull-down
resistors, congurable trigger levels, detecon by rising or falling edge,
excitaon voltage congurable from 5 Vdc to 18 Vdc.
Opons for output and control with 1, 2 and 3 relays, transistor out-
puts, SSR drive controls, isolated analog outputs, communicaons in
Modbus RTU, RS-485 ASCII and RS-232. Special opons with 4 and 6
relay outputs.
Independent alarms congurable as maximum or minimum, with 1 or
2 setpoints per alarm, hysteresis, independent acvaon and deac-
vaon delays and control for inverted relay.
Front protecon IP65. Connecons by plug-in screw terminals. For in-
dustrial applicaons.
• ‘Fast access’ menu to selected funcons, accessible with key UP (5)
(see secon 1.19.12)
• Funcon ‘On power up’ for system protecon on rst ‘cold’ start-up
or automac reset (see secon 1.19.15)
• Special ‘FAST’ mode for fast counng applicaons (see secon 1.16)
• Special ‘SLOW’ mode for slow ratemeter applicaons (low frequency
applicaons) (see secon 1.15)
• Direct conguraon for most usual sensor, at the ‘SnSr / Auto’ menu
(see secon 1.19.10)
• Funcon ‘Trigger Sense’ helps to detect the correct trigger level (see
secon 1.13)
Mulple display lters, memory for maximum and minimum reading,
password protecon, 5 brightness levels.
