Now for Frequency and Digital Signals

ISO-FU-S2 has been developed for conditioning of arbitrary periodic frequency signals with amplitudes from 500 mVpp to 100 Vpp. Each channel handles 2 differential tracks and has a digital input for e.g. synchronisation pulses. Sensors are fed per channel by an integrated isolated power supply. Operating modes are FU (frequency range 5 Hz to 1 MHz) and Incremental Counter (100 to 1 million pulses).

DIO-8-D is processing up to 8 digital input signals (high 3.5 .. 60 V, low –30 .. +1 V). The inputs are optically decoupled. The outputs are stuffed with 8 relays (max. 2 A, 220 V). The version DIO-8-Z4-D offers in addition up to 4 inputs for digital frequency signals. They can be set to FU or Incremental Counter mode.
