Speedometer TA327401
Speed display in 32x74 mm format; input: PNP, NPN, TTL; output: 2 relays
- Tachometer 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 tachometer TA327401 is the ideal solution for monitoring speeds. Almost all commercially available pulse sensors can be connected via three function inputs (NPN/PNP/TTL). In addition to the free setting of the time base and number of pulses per revolution, the filter function and the minimum and maximum value display ensure optimum adaptation to the application requirements. 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 tachometer impresses with its robust, compact housing and brilliant display.
Display:
2-line LED display
Upper line: Actual value, 4-digit, green with 10.2 mm digits
Lower line: setpoint, 4 digits, red with 7.6 mm digits
Indicators:
Two red indicators for relay output status and one yellow indicator for serial communication.
1, 2 ON when output is active.
R ON for serial communication
The display of the maximum or minimum value is indicated by a short
short text in the 1st line.
Keyboard:
4 buttons for programming and setting the setpoint.
Inputs:
Three digital inputs adjustable as PNP, NPN or TTL.
Programmable switching thresholds for activation as high active/low active/rising edge or level-controlled.

Input frequency:
maximum 100 kHz.
Relay output:
1 changeover relay with 5 A @ 250 VAC and 1 NO contact with 5 A @ 250 VAC.
Sensor supply:
24 VDC
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.
Data protection:
Password-protected access to setpoint, alarm values and parameters.
Programming:
Programming and operation is menu-guided via the front buttons.
