Digital positioner controls pneumatically actuated process valve
Mike EdwardsProducts CMSH digital positioner festo pneumatic actuator process valve
The CMSH is an intelligent, digital positioner from Festo controls the position of a process valve that is actuated by a pneumatic actuator.
CMSH units have an ambient temperature range of -40° to 80°C and an IP66/67 rating.
The positioner is a 4 to 20 mA loop-powered 2-wire device, meaning that an additional power supply is 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.
