About Omron NX-CIF105 Interface Unit
The NX-CIF105 is an Omron NX-series communications interface unit designed to connect compatible NX systems with RS-422A/485 serial devices. Its isolated interface, selectable 2-wire or 4-wire operation and multidrop capability make it suitable for long-distance communication with instruments, inverters, controllers and other industrial equipment.
Key Features
- Isolated RS-422A/485 interface: Uses transformer, photocoupler and digital-isolator technology to separate the communication circuitry.
- Flexible wiring modes: Supports half-duplex communication over two wires or full-duplex communication over four wires.
- Long-distance multidrop networking: Supports up to 32 nodes over a maximum total cable length of 1,200 m.
- High-speed serial communication: Provides selectable baud rates from 1,200 to 230,400 bps.
- No-protocol data exchange: Sends and receives serial data without requiring a predefined communication protocol or automatic conversion.
- Serial line monitoring: Allows transmitted and received data logs to be checked in Sysmac Studio during commissioning and troubleshooting.
- Space-saving push-in wiring: Uses a 12 mm-wide design and an NX-TBC162 screwless terminal block for compact panel installation.
