What Does This PLC Controller Do?

The KR28 PLC controller receives switching signals from field devices through its 16 digital inputs and controls connected equipment through its 12 relay outputs. Its dual Ethernet ports support network communication, while the PID function supports process-control applications that require bidirectional adjustment.

Key Features
16 digital inputs — receive on/off signals from sensors, switches, and other field devices.
12 relay outputs — control external circuits through relay-based output channels.
Dual Ethernet ports — provide two network connections for communication and integration.
16-channel bidirectional PID — supports multi-channel PID control requirements.
Free Ethernet protocol — supports Ethernet communication based on the provided protocol capability.
SD card support — supports use of an SD card with the PLC.
50KB program space — provides storage capacity for PLC control programs.
Compatible With
CPU SR30 configuration selection
Version 2.8 programming software
1200 PLCs for direct communication
1500 PLCs for direct communication
Easy to Set Up

Configure the KR28 as CPU SR30 in the programming software. Connect the 24VDC supply, wire the required digital input and relay output circuits, then connect Ethernet devices through the two network ports as needed. Install and use an SD card when required by the application.
