• Input Resistance: 100 kΩ

Sensor Signal Output

• Voltage Output Range: 0–4.1 V (Output = 0.15 × sensor signal)

• Accuracy: ±1% full-scale

• Frequency Response: 0–16 kHz (-3 dB ±20%)

• Permissible Load: 1 MΩ

• Internal Resistance: 10 kΩ

Dynamic Pulse Output (TTL)

• Output Type: TTL pulses, open- and short-circuit protected

• Nominal Voltage: 0–5 V

• Frequency Range: 0–20 kHz

• Permissible Load: ≥1 kΩ

• Internal Resistance: 5.1 kΩ

Pulse Output (Optocoupled)

Characteristic Value Signal Processing

• Processing Method: Input pulses are standardized by the internal processor

• Calculation: Characteristic value = Input pulse frequency ÷ number of teeth on trigger wheel

• Maximum Measuring Range: Limited by 20 kHz maximum input frequency

• Max Trigger Wheel Teeth: 255 (max 4700 rpm)

Current Outputs

• Output 1: 0/4–20 mA, galvanically isolated, ±0.1% full-scale accuracy, 16-bit resolution

• Output 2: 0/4–20 mA, non-isolated, with analog feedback for comparison, ±0.1% full-scale accuracy, 16-bit resolution

• Speed Scaling: One speed zoom per current output, ±0.1% accuracy

Channel Monitoring and Visualization

• Function: Continuously monitors each channel’s speed signal and compares it with the other channels’ pulses and current outputs for maximum safety

• Status Indication: Dual green LEDs on front panel indicate faults

• Fault Signaling: Via opto-decoupled collector/emitter output

Applications

Ideal for rotational machinery speed monitoring, automated production line speed control, industrial process measurement, and safety monitoring systems.
