Electropneumatic positioner CMSX series

digitalanalogfor cylinders

Affordable and reliable: CMSX for pneumatic linear and quarter turn actuators! Outstanding value for money, energy-efficient, analog or digital feedback signals for incredibly reliable processes, and definable safety settings. • Digital, electropneumatic positioner • Simple and efficient position control of single-acting and double-acting pneumatic rotary and linear actuators • With integrated or external path/angular detection • Simple commissioning through automatic initialization function • Intuitive menu navigation • 4-conductor technology • Variants with safety functions Function and application The CMSX is a digital electropneumaticpositioner that enables simple andefficient control of the position ofprocess valves actuated by pneumaticactuators. This robust and compactpositioner can be mounted onactuators using a mechanical interfacein accordance with VDE/VDI 3845-1(IEC 60534-6-2). There are productvariants for single or double-actingactuators, different flow rates andsafety settings (fail-safe, fail in place).In addition, there are product variantsfor connecting external displacement/angular sensors to remotely control theposition of process valves.Commissioning is simple and robustthanks to an automated initialisationfunction. For setpoint specification0/4 … 20 mA current signals or0 … 10 V voltage signal are used, andfor analogue position feedback a4 … 20 mA current signal is used.
