Key Specifications of Omron CP1L-EM30DR-D PLC
Power Supply and Voltage
The Omron CP1L-EM30DR-D PLC operates on a 24V DC power supply with a tolerance range of 20.4V to 26.4V. This wide voltage range ensures stable operation in industrial environments where fluctuations may occur. The requirement for DC power also ensures compatibility with most industrial control panels.
Input and Output Configuration
This PLC features 18 digital inputs and 12 relay outputs. The inputs are PNP/NPN compatible, which provides flexibility in connecting a variety of sensors and switches. The relay outputs can handle up to 2A per channel, making them capable of switching larger loads such as solenoids, contactors, and relays. The minimum load current of 10mA ensures accurate switching even for low-power devices. For deeper understanding, see this article on Relay vs. Transistor Outputs.
Memory and Program Capacity
The Omron CP1L-EM30DR-D PLC offers a 10K steps program memory along with a 32Kword data memory. This combination allows for the storage of complex logic, data handling, and advanced control sequences. A backup battery ensures data retention, safeguarding counters, timers, and holding memory areas during power loss.
High-Speed Processing
With 4 high-speed counter inputs (up to 100kHz) and 2 high-speed pulse outputs (up to 100kHz), the CP1L-EM30DR-D is suitable for motion control applications. These functions are critical for applications that involve encoders, stepper motors, or servo drives where precision timing and control are essential.
Communication and Networking
The PLC includes a built-in Ethernet port for TCP/IP communication, enabling seamless integration with SCADA systems, HMIs, or other PLC networks. Additional communication can be achieved through optional modules such as RS-232C, RS-422, or RS-485, making the system highly adaptable.
Programming Interface
Programming is carried out using Omron’s CX-Programmer software, part of the CX-One suite. The Omron CP1L-EM30DR-D PLC supports ladder diagram programming and is instruction-compatible with higher-end Omron PLCs such as the CP1H, CJ1, and CS1 series. This compatibility makes it easy to scale projects without rewriting existing logic.
Physical Design and Installation
The compact design (130mm x 90mm x 85mm) with DIN rail mounting ensures that the PLC can be easily installed in control cabinets. Its operating temperature range of 0°C to 55°C ensures reliability in varied industrial environments.
