Description

KR20 relay PLC controller featuring 12 digital inputs, 8 relay outputs, dual Ethernet, signal board support, and SD card support.

The KR20 relay PLC controller provides 12 digital inputs and 8 relay outputs for compact automation control systems. It combines dual Ethernet ports, 24VDC power, 50KB program space, and support for free Ethernet protocol. It is suitable for users who need flexible I/O control, PID functions, and direct communication capability with 1200 or 1500 PLCs.

Technical Specifications

What Does This PLC Controller Do?

The KR20 PLC controller receives digital signals from field devices and controls connected loads through its eight relay outputs. Its dual Ethernet ports support network-based integration, while the PID function provides control capability for applications requiring process adjustment.

Key Features

• 12 digital inputs — receive switching signals from sensors, buttons, and field devices.
• 8 relay outputs — control external loads through relay-based output channels.
• Dual Ethernet ports — provide two network connections for communication and integration.
• 16-channel bidirectional PID — supports PID control requirements across multiple channels.
• Two signal board slots — allows installation of up to two compatible signal boards.
• 50KB program space — provides storage capacity for PLC control programs.
• SD card support — supports use of an SD card with the PLC.

Compatible With

• CPU SR20 configuration selection
• Up to two signal boards
• 1200 PLCs for direct communication
• 1500 PLCs for direct communication
• Version 2.8 programming software

Easy to Set Up

Configure the KR20 as CPU SR20 in the programming software. Connect the 24VDC power supply, wire field inputs and relay outputs, then use the Ethernet ports for network communication as required. Signal boards and an SD card can be installed when needed.

Order With Confidence

The KR20 combines relay I/O, dual Ethernet communication, expandable signal-board capability, and PID control functions in one PLC controller.
