OMRON C60K-CDR-C K-Type CPU PLC

The OMRON C60K-CDR-C is a K-type Programmable Controller CPU unit that provides a complete control solution for industrial automation applications. With 60 built-in I/O points and relay outputs, this PLC offers an effective way to automate processing, manufacturing, assembly, packaging, and many other processes while saving time and reducing operational costs.

Product Overview

The C60K-CDR-C is part of OMRON's K-type Programmable Controller family, which has been widely adopted in industrial automation for its reliability and ease of use. The K-type controllers are equipped with large programming instruction sets, comprehensive data areas, and other features that enable direct control of industrial processes. The CPU unit contains the user program and connects to input and output devices, monitoring input status and activating outputs according to the programmed logic.

The K-type operation manual describes the characteristics and capabilities of these programmable controllers, including detailed information about programming operations, instructions, and other aspects of operation that require attention. Distributed control systems can be designed using multiple K-type units, allowing centralized monitoring and supervision of several separate controlled systems through a host computer connection.

I/O Configuration

The C60K-CDR-C provides a total of 60 I/O points, comprising 32 input points and 28 output points. The input section is designed for 24 VDC operation, providing compatibility with a wide range of industrial sensors and switches. The output section uses relay outputs with sockets, offering the flexibility to switch both AC and DC loads with electrical isolation between the PLC and field devices.

Relay outputs are particularly suitable for applications requiring switching of contactors, solenoids, pilot lights, and other loads where the switching frequency is moderate. The sockets simplify replacement of output relays if service becomes necessary, reducing system downtime during maintenance.

Programming and Operation

K-type programmable controllers utilize ladder-diagram programming methods, a graphical programming language that uses symbols and control concepts originating in relay-based control systems. This familiar approach makes the PLC accessible to technicians and engineers with backgrounds in traditional electrical control systems.

The programmable controller operates by monitoring the status of all input points and turning corresponding input bits ON or OFF based on the actual field conditions. The user program then evaluates the input bit status and determines which output bits should be activated. Finally, the output points are turned ON or OFF based on the status of the output bits, completing the control cycle. This scan-based operation repeats continuously, providing real-time control of the industrial process.

System Expansion

The C60K-CDR-C can utilize a number of additional units including dedicated Special I/O Units that can be used for specific tasks such as analog I/O, high-speed counting, and temperature control. Link Units can also be added to build more highly integrated systems, allowing multiple PLCs to share data and coordinate operations. A maximum of 10 16-bit registers can be used for each CPU unit for the expansion I/O units added to the system.

This expansion capability allows the basic C60K-CDR-C system to grow with application requirements, from simple standalone machine control to complex distributed control networks. Monitoring and supervision can be performed through a host computer, connecting the controlled system to enterprise data systems and enabling automatic adjustments to compensate for changing production requirements.

Environmental Specifications

The C60K-CDR-C is designed for reliable operation within an ambient temperature range of 0 to 55°C during operation, with storage capabilities extending to wider temperature limits. The unit should be installed in a clean, dry location protected from excessive vibration, moisture, and corrosive atmospheres to ensure long-term reliable performance.

Proper installation practices include maintaining adequate clearance around the unit for heat dissipation and access for wiring and maintenance. The relay outputs have specified electrical ratings and expected mechanical and electrical service life that should be considered when designing applications with high-cycle switching requirements.
