## Tachometer TA327401 

Tachometer with rotating direction indication 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:** 

TA327401 

The compact small tachometer TA327401 allows to read the frequency (max 100KHz) of a signal from single or double (bidirectional encoder) input. 2 universal digital inputs are available (NPN/PNP/contact) for external commands like output activation or Hold/ Stop current visualization; one input it is also analogue in order to allow setpoint modification by external potentiometers. 

Due to the two different modes and the indivation of the rotating direction, the tachometer 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|



TA327401
