Counter/frequency display ZD327401
Counter/frequency display in 32x74 mm format; input: PNP, NPN, TTL; output: 2 relays
- Counter/frequency display in 32 x 74 mm format
- Universal AC and DC power supply
- Input frequency up to 100 kHz
- 2-line LED display
- Simple programming via keypad or software
- Two switching outputs

The compact small pulse counter ZD327401 can be used both as a preset counter and as a frequency display. Almost all commercially available pulse sensors can be connected via three function inputs (NPN/PNP/TTL). The counting direction can be determined and displayed via the internal phase discriminator or the corresponding wiring of the function inputs. A function input can also be connected via a potentiometer to specify the setpoint. In addition to an excellent price/performance ratio and high quality, the counter impresses with its robust, compact housing and brilliant display.

Function inputs:
Gate input, hold, direction selection,
setpoint setting (I3).
Input frequency:
Minimum 1 Hz to maximum 100 kHz.
Relay output:
1 changeover relay with 5 A @ 250 VAC and 1 NO contact
with 5 A @ 250 VAC.
Sensor supply:
24VDC
- 30 mA with 24 VAC supply
- 40 mA with 24 VDC supply
- 60 mA with 110 to 230 VAC supply.
Power supply:
24 VAC/DC to 230 VAC/DC +/-15 %, 50/60 Hz; 2W.
