SpeedSys T20 Conditioner

2-Channel Speed Monitor, Transmitter & Controller

Istec International B.V.

  • Accepts signal inputs from 3-wire voltage sensors (Hall-effect & proximity),
  • Accepts 2-wire voltage signals or digital input signals from encoders.
  • Dynamic monitoring, comparing chns, reverse rotation, creep and standstill.
  • Input Voltage Ranges from 20 mVrms to 80 Vrms
  • Input Frequency capable from 0.025 Hz up to 35 kHz (200kHz for Digital Pulse)
  • Four configurable high speed relays (10 ms response time) for multiple speed functions
  • Two highly accurate analog outputs (4-20 mA or optional 2 – 10 V)

Details

Redundant input channels

The SpeedSys T20 connects every common speed sensor with a industry standard output. The 2-channel monitoring and switching device is ideal for speed protection and monitoring on rotating machinery. 

System features

  • 2 independent channels
  • Redundant sensor inputs
  • Redundant power supply
  • 4 high speed relays
    • 2 configurable trip relays (DPST)
    • 2 configurable alarm relays (SPST)
  • Fast 8 millisec hardware response time (relays)
  • Highly accurate analog output signals (4-20 mA)
  • Signal filter and line amplifier
  • Software-selectable cross channel connection: Outputs can be programmed to use the sensor signal of other PCBs in the same device.
  • Software-programmable voting: Allows programming of various voting structures like 1oo2, 2oo2, 1oo3, 2oo3, 3oo3.
  • Reverse rotation: With two sensor signals with a phase difference, the rotational direction of the machine can be determined.
