STI-N118

Code: STI-N118
  • pulse rate / period meter in wall mounted IP 67 case
  • rotational / linear speed control
  • revolution / movement period control
  • 0 or 2 REL / OC outputs
  • analogue output: active or passive, power supply output: 24V DC
  • RS-485 / Modbus RTU
  • "over" signalling when the measuring range is exceeded
  • free configuration software S-Config
Description

The STI-N118 tachometers are encased in a tight, wall-mounted housing (IP 67) and designed to control rotational or linear speed of moving objects. The device is also able to measure frequency. As an additional advantage the device can convert the rotational / linear speed into inverse values, and to display the single revolution period or process duration. The REL / OC control outputs can be programmed depending on the instantaneous value of rotational speed. Additionally the counter may be equipped with analogue outputs, according to the customer selection: active current output, passive isolated current output or active voltage output. The counter may be configured with no need to open the case, by using the remote controller or with free S-Config software via the RS-485 communication port.
