Description
The KEYENCE KV Series communication units are expansion modules designed for the KV-8000/7500/7300/5500/5000/3000 series programmable controllers. This family includes Ethernet (KV-LE21V), EtherNet/IP (KV-EP21V), and Serial Communication (KV-L20R/L20V/L21V) units, enabling seamless integration of KV PLCs into industrial networks. These modules facilitate high-speed data exchange, protocol conversion, and connectivity with HMIs, SCADA systems, and other PLCs, supporting both standard Ethernet and industrial fieldbus protocols.
Key Features
- Ethernet Unit: KV-LE21V (Standard TCP/IP, FTP, Mail, DNS)
- EtherNet/IP Unit: KV-EP21V (Industrial protocol, implicit/explicit messaging)
- Serial Units: KV-L21V (RS-232C/RS-422A/RS-485), KV-L20V, KV-L20R
- High-Speed Communication: Supports MC protocol and custom socket communication
- Software Integration: Compatible with KV Studio and KV Data Builder
- Multi-CPU Support: Compatible with KV-8000 to KV-3000 series
- Compact Design: Direct plug-in to CPU/expansion base unit
- Country of Origin: KEYENCE Standard (Japan)
