## Counter/Preset Counter ZD327401 

Conter/Preset Counter in 32 mm x 74 mm format Universal AC/DC power supply Input frequency up to 100 kHz 2-line LED display Easy programming by front keys or software Two relay outputs 

**Excitation:** 24 VDC 

- 30 mA( 24 VAC power supply) - 40 mA(24 VDC power supply) 

- 60 mA(110 bis 230 VAC power supply). 

## **Supply:** 

24VAC/DC to 230 VAC/DC +/-15 %, 50/60Hz; 2 W 

**Data security:** Password-protected access to setpoint, alarm values and parameters. 

**Programming:** Programming and operation is menu-guided via the front keys. With the programming kit, the controller can also be programmed by a Windows ™- software. The memory card has an internal battery. Thus, the programming of the devices is possible without the supply (up to 1000 programming with a battery). 

## **Wiring plan:** 

ZD327401 

The compact small counter ZD327401 can be set in two different modes: Single or Double counter, all with independent setting. 3 universal digital inputs are available (NPN/PNP/contact) can be used for bi-directional encoders reading, UP/DOWN counter function, LOCK/HOLD to lock or hold current visualization. 

One input is also analogue in order to allow setpoint modification by an external potentiometer. 

Due to the two different modes and the scaling features, the counter is usable for a lot of different applications. In addition to an excellent cost effectiveness and high quality, the counter offers a rugged, compact housing and a brilliant display. 

**Display:** 2-line LED-Display Upper line: Counting value, 4-digit, green with 10.2 mm digits Lower line: Setpoint, 4-digit, red with 7,6 mm digits 

**Indicators:** Two red indicators for status relays outputs and a yellow indicator for serial communication. 

1, 2: ON, when output active R: ON when serial communication is active 

**Buttons:** 4 front keys for programming and setting up the setpoints. 

**Inputs:** Three digital inputs can be configured as PNP, NPN or TTL.Programmable thresholds for activation as a high / low active active / rising edge or level triggered. 

|Logic<br>level<br>Input<br>signal|NPN|PNP|TTL|
|---|---|---|---|
|High|< 4,7 V|>5,7 V (I1, I2)<br>>12,4 v (I3)|>2,5 V|
|Low|> 5,7 V|< 4,7 V (I1, I2)<br>< 10,2 V (I3)|< 2,0 V|



ZD327401
