Product catalog summary

Overview: The MELSEC-WS series is a compact safety controller developed by Mitsubishi Electric in collaboration with SICK. It is designed for small to medium safety systems, offering easy settings and flexible expandability.

Specifications: The controller supports 255 function blocks with a scan cycle starting from 4 ms. It features an RS-232 interface and complies with ISO13849-1 PLe and IEC61508 SIL3 safety standards. The module is 22.5 mm wide and can expand to include up to 12 safety input/I/O modules, 4 safety relay output modules, and 2 network modules.

Components: Key components include WS0-CPU0 and WS0-CPU1 CPU modules, WS0-MPL0 memory plug, WS0-XTIO safety I/O combined module, WS0-XTDI safety input module, WS0-4RO safety relay output module, WS0-GETH Ethernet interface module, and WS0-GCC1 CC-Link interface module.

Features: The controller offers intuitive configuration through a Setting and Monitoring Tool, allowing easy logic creation using labels and function blocks. It supports fast shut-off with an 8 ms response time. The EFI interface on the WS0-CPU1 module enables diagnostics and settings for SICK’s safety products.

Connectivity: The MELSEC-WS can connect to Ethernet and CC-Link networks for non-safe communication, allowing remote maintenance and monitoring of data such as CPU logic results and I/O signal status.

Environmental and Safety Standards: The controller operates under various environmental conditions, conforming to IEC 61131-2 standards for vibration and shock resistance. It is suitable for installation inside control panels and can operate at altitudes up to 2000 meters.

Applications: The MELSEC-WS is ideal for ensuring the safe operation of stand-alone machines or systems, with the ability to expand I/O points up to 144. It is suited for environments requiring compact and efficient safety solutions.

Procedures and Features: The MELSEC-WS allows network connections via the EFI interface on the WS0-CPU1 CPU module, enabling retrieval of safety data, settings adjustments, and diagnostics on SICK’s safety products. It supports easy CPU module replacement without rewriting parameters and programs, facilitated by a memory plug.

Network and Interface: The system supports connections to various equipment via network interfaces, including CC-Link and Ethernet. The WS0-GCC1 and WS0-GETH modules provide CC-Link and Ethernet interfaces, respectively, allowing for fast shut-off with an 8 ms response time.

General Specifications: Operating conditions include ambient temperatures from 10 to 95% RH, non-condensing, and vibration resistance conforming to IEC 61131-2 standards. The system is designed for installation inside control panels at altitudes up to 2,000 meters.

Safety and Performance: The safety controller meets Category 4 (EN/ISO 13849-1) and SIL3 (IEC 61508) standards, with a performance level of PLe. It features a protection class of IP20 for terminals and IP40 for housing, with EMC standards EN61000-6-2 and EN55011 (Class A).

Warranty and Support: Mitsubishi Electric offers a one-year warranty from the date of delivery or eighteen months from the date of purchase, covering defects in material and workmanship. Repairs outside Japan are handled by local authorized service centers, with repair services available for four years post-discontinuation of a product model.
