When a machine needs to control multiple sensors, actuators, analog signals, and communication networks from one compact controller, using separate modules can make the control system larger and harder to manage. A compact PLC with built-in digital, analog, serial, Ethernet, and CAN interfaces can simplify the control architecture while keeping the system programmable and expandable.
Beijer BCS-XP325, Compact CODESYS-based PLC Controller
The Beijer BCS-XP325 is a compact CODESYS-based PLC controller designed for machine and industrial automation applications. It combines programmable logic control with integrated digital and analog I/O, allowing the controller to receive signals from sensors, process control logic, and operate connected equipment without requiring a separate controller for each basic function.
The controller provides 16 digital inputs and 16 transistor digital outputs for connecting common industrial devices such as switches, sensors, indicators, relays, and actuators. It also includes voltage and current analog inputs and outputs, plus RTD analog inputs, allowing it to work with continuously varying process signals and temperature measurement devices.
For machine communication, the BCS-XP325 includes Ethernet TCP/IP, RS-485, CAN, and a USB host port. CANOpen Master and J1939 Manager protocols are supported, making the controller suitable for systems that need communication with compatible automation devices and CAN-based equipment.
The controller uses CODESYS programming and supports Instruction List, Structured Text, Ladder Diagram, Sequential Function Chart, Function Block Diagram, and Continuous Function Chart. Online changes, watchdog functionality, real-time clock operation, diagnostic indication, and configurable memory resources support programming, monitoring, and maintenance of automation applications.
Designed for compact control-panel installation, the BCS-XP325 has a 215.5 x 98.8 x 34.0 mm module size and operates from a 24 Vdc nominal supply. Conformal coating, IP20 protection, a -20 to 60 °C operating temperature range, 1,500 Vac isolation specifications across multiple interfaces, and CE, UL, cUL, DNV, and UL C1D2 certifications support its use in industrial and specified marine or hazardous-location installations.
