F3YC08-0N

The Yokogawa F3NC02-0N-Z01 is a highly reliable 2-channel Isolated Pulse Input Module designed for the Yokogawa FA-M3 series of programmable controllers (PLCs). This module is specifically engineered to interface with pulse-output field instruments, such as turbine flowmeters and rotary encoders, which are critical in applications like flow computation, batching, and speed monitoring.

Parameters
Parameter Specification Details / Notes
Model Number F3NC02-0N-Z01 The -Z01 suffix often indicates a specific version or packaging.
Module Type Isolated Pulse Input Module 2 channels
Isolation Channel-to-Channel & Channel-to-Logic Photocoupler isolation and DC/DC converter isolation.
Input Signals Contact, Line Driver (Differential), Voltage Pulse (TTL/CMOS) Selectable via a DIP switch on the module.
Rated Input Voltage 5 V DC / 12 V DC / 24 V DC (Depends on mode) Configurable for different input types.
Maximum Input Frequency Line Driver (Differential) mode: 500 kHz
Voltage Pulse (TTL) mode: 200 kHz
Contact Input mode: 20 Hz
Minimum Pulse Width 1 µs (for 500kHz operation)
"ON" / "OFF" Level Varies by mode.
e.g., TTL: "ON" ≥ 2.0 V, "OFF" ≤ 0.8 V See manual for exact specifications for each input type.
Counter Function 32-bit ring/linear counter per channel (0 to 4,294,967,295)
Scaling Function Yes Converts pulse count to engineering units (e.g., liters, gallons, kg).
Digital Filter Adjustable (0.1, 0.5, 1, 5, 10 ms) Used to eliminate chattering and electrical noise.
Internal Current Consumption 5V: 0.65 A Power drawn from the PLC's backplane.
Connection Method Removable Terminal Block
Compatible PLC System Yokogawa FA-M3 Series Must be installed in an FA-M3 base unit.
Status Indication LEDs per channel: RUN, ALM, INPUT Indicates power, warnings, and input signal status.
