Short description:
The 857-500 Frequency Transducer collects 0.1–120kHz signals from
NAMUR, NPN or PNP sensors and converts them into analog standard signals.
Characteristics:
• PC configuration interface
• Signal acquisition from NAMUR, NPN or PNP sensors
• Calibrated scale switching
• Safe 3-way isolation with 2.5kV test voltage to EN 61140
