Electronic pulse counter / Pulse counter

Detailed description

Pulse counter for DS-48 panel

(2x 4-digit display: 1x counter, 1x target value)

General specifications of the DS-48 pulse counter:

2x 4-digit display, 1x preset value,

1x output relay OUT,

clock/down counter

Counts signals from mechanical switches, PNP/NPN inductive proximity sensors, and incremental encoder inputs.

Password protection.

Selectable input frequency: 20, 50, 2500, 7500 Hz

Calibration constant: 0.001.....9.999

Selectable decimal point: 0, 0.0, 0.00, 0.000

7 input functions / 9 output functions:

- Counting,

- countdown,

- addition/counting from two simultaneous inputs,

- counting pause/counting controlled by the second input,

- input negation controlled by the second input,

- addition/subtraction from the rising edge / falling edge / both edges simultaneously,

- addition on the rising edge / subtraction on the falling edge / negation of the function with the second input

Adjustable OFFSET of the calculated value

Output relay: turns on when the value is reached and remains on until reset or pulse in the range of 0.1.....999.9 seconds.

Remembers the pulse counting value and the output relay state during the last power outage and can be reset after the first power-up.

Reset by button on the front panel or signal on the reset terminal (12).

EEPROM memory for storing settings.

Installation notes:

Use a shielded twisted signal cable and ground the shielding. Keep all signal cables away from circuit breakers, inductive loads, devices/cables emitting electrical noise, and power cords.

Avoid environmental influences such as humidity, vibrations, dirt, and high/low temperatures.

Use a fuse (F250mA 250VAC) at the power supply input of the equipment.

Use an appropriate cable for power supply. Follow safety rules during installation.

Before the encoder, preferably use the option (Inpt = Phs1), select (Frequency = 20) for counting the ON-OFF mechanical switch pulses,

Select the optimal minimum input frequency that suits your application.

For Inpt = 1u2u, 1u2d, Phs2; the input signal frequency must not exceed ½ of the selected input frequency if both inputs are used.

Pre Inpt = Phs4; the frequency of the input signal must not exceed 1/4 of the selected input frequency if both inputs are used.

Technical parameters:

Dimensions / opening: 48x48x96 mm / 44x44 mm

Display: 2x4 digit 7-segment LED display.

Number of inputs: 2 x (Max: 7500 Hz, 5-30 V)

Input type: mechanical switch, PNP/NPN inductive sensor, NPN/PNP/totem-pole encoder output.

Input frequencies: 20, 50, 2500, 7500 Hz.

NPN sensor selection.

The reset input is always PNP.

No "npn select" is connected before the totem or PNP sensors.

Power supply voltage: 100...240 V AC, 50-60 Hz.

Power consumption: < 8 VA

Output (OUT):

1x SPDT relay 250VAC, 2A, resistive load, terminals 4=COM, 3=NO, 5=NC,

1x control SSR - NPN, 30V, max 100mA, terminal 13=SSout, 14=GND

Sensor power supply: terminal (9) 12 VDC, 50 mA (max.), unregulated

Conversion temperature: -20°C ... +55°C
