Festo’s New Digital Positioners CMSH

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.
