Festo’s New Digital Positioners CMSH

MC Festos New Digital Positioner CMSH 1 400x275

October 18, 2022

 

The CMSH is an intelligent, digital positioner. It controls the positin of a process valve that is actuated by a pneumatic actuator. Thanks to the large ambient temperature range of –40°C to +80°C and its high degree of protection (IP66/67), it can also be used under harsh operating conditions. The CMSH is a 20mA loop-powered 2-wire device. An additional power supply is therefore not required.

Configuration and operation can be performed locally on an LC display using operating buttons. A HART interface permits remote access and integration into higher-level systems. There are product variants for single- or double-acting actuators with safety settings (failsafe, fail in place). The product is suitable for attachment to actuators with a mechanical interface in accordance with VDI/VDE 3845-1 (IEC 60534-6-2) or VDI/VDE 3847-2.

The product variant CMSH-S has an internal position sensor for detecting displacement/angle. Alternatively, an external potentiometric position sensor can be connected to the positioner on all product variants.

Access Management for Your Plant and Machinery

With PILZ’s “Identification and Access Management” portfolio, they offer you a comprehensive range of products, solutions and software for the implementation of safety as well as security tasks. Below you’ll discover more about potential applications, from simple authentication to complex access permissions, and access management through to safe operating mode selection, maintenance safeguarding and safeguarding of data and networks. Experience safety and security in one system!

This solution ensures that a machine cannot resume operation while people are still in the danger zone. The maintenance safeguarding system “key-in-pocket” is designed for machines with danger zones, which are protected by a safety fence and which staff need to access – robot cells for example. In comparison with conventional lockout-tagout (LOTO) systems, maintenance safeguarding with the key-in-pocket solution is implemented via RFID keys with corresponding permissions and a safe list in the PILZ controllers. As a result, it provides a purely electronic restart protection and makes both mechanical interlocking devices and warning tags redundant.
