Up/Down Counting Meter
K3NC
An Ideal Interface for High-speed Up/Down
Counting and Serial Communications
• 50-kHz input range for high-speed signal processing.
• A wide selection of outputs: relay, transistor, BCD, linear, or
communications.
• Prescale function available, which displays in units of actual
physical parameters (length, volume, etc.).
• Built-in sensor power supply (12 VDC, 80 mA).
• Banks with four set values and four prescale values.
• Five-stage comparative outputs available.
• Compact 1/8 DIN size.
• Conforms to EMC standards, EN61010-1 (IEC1010-1).
• UL/CSA approved.
