Package size: 11X10X14CMOmron CP1W-CIF11 RS-422A/485 Communication Interface Unit - Industrial-Grade Serial Connectivity Solution
The Omron CP1W-CIF11 represents a premium industrial communication interface unit engineered for seamless integration with Omron CP1 series programmable logic controllers (CP1L, CP1E, CP1H). This rugged RS-422A/485 interface module delivers reliable serial communication capabilities for demanding industrial automation environments. Featuring advanced photocoupler isolation technology (2,000 V AC for 1 minute protection) and screw terminal connections, the CP1W-CIF11 ensures stable data transmission even in electrically noisy factory settings. With its compact 30 × 90 × 65 mm (1.18" × 3.54" × 2.56") footprint and minimal 0.15 W power consumption, this unit provides an efficient communication solution without compromising panel space.

Installation Guidelines and Technical Considerations
The CP1W-CIF11 interfaces directly with compatible Omron CP1 series PLCs via the expansion connector on the CPU unit. For RS-422A applications, implement point-to-point connections using twisted pair cabling with proper shielding. In RS-485 multi-drop configurations (up to 1,200 meters maximum cable length), install 120Ω termination resistors at both ends of the network and consider adding bias resistors if necessary. The unit's DIP switches (located under the terminal cover) must be configured according to the desired communication standard before operation. Ground the FG terminal to the panel ground using a thick (minimum 2 mm²) wire for optimal noise immunity. For proper heat dissipation, maintain at least 10 mm clearance above and below the unit during installation.
