YOKOGAWA F3LC31-2F Communication Module
Description
YOKOGAWA F3LC31-2F is an RS-422/RS-485 communication interface module for the FA-M3 programmable controller system, enabling serial data exchange with external devices such as HMIs, drives, and intelligent instruments.
Features
Supports high-speed serial communication with configurable protocols, provides electrical isolation, and integrates directly into the FA-M3 I/O chassis for industrial automation networks.
Technical Specifications
Communication Interface
- Port type: 1 × RS-422 / RS-485 (selectable via internal jumper)
- Data rate: up to 115.2 kbps
- Communication distance: up to 1200 meters (at lower baud rates)
- Driver/receiver: full-duplex (RS-422) or half-duplex (RS-485)
Electrical & Isolation
- Isolation voltage: 500 V AC between field and logic circuits
- Termination resistor: built-in, switchable
- Supported protocols: Modbus RTU, YOKOGAWA proprietary serial protocol
Mechanical & Environmental
- Mounting: occupies one I/O slot in FA-M3 base unit
- Operating temperature: 0 °C to +55 °C
- Humidity: 5% to 95%, non-condensing
- Power consumption: approx. 2 W from internal bus
