General

Proportional 0-10V or 3-position modulating or On/Off control of Frese OPTIMA Compact valves in heating, ventilating and air conditioning systems.

The actuator can be mounted on the valve by hand and without the need of a specific tool.

Due to the compact design of the actuator, it is particularly suitable for installations where space is limited.

Features

• Nominal stroke on proportional 0-10 V or 4-20 mA
• actuator up to 5.5 mm. Presetting from factory 2.5 or 5.5 mm
• Auto calibration to all valve strokes for version with feedback signal (53-1184)
• 3-position, 0-10 V DC or 4-20 mA control signal. Other control signals can be selected by use of dip switches
• Direct assembly with union nut to the neck of the valve. No tools required
• Bi-color LED for status and diagnostic
• Linear or EQ % characterization available on the same actuator
• The actuator is short-circuit-proof and protected against polarity reversal
• Plug-in cable for supply voltage and control signal
• Small outer dimensions
• Removable cable
• Auto zero detection
• IP 43 for standard actuator versions. IP 54 protection for version with feedback signal (53-1184)
• Voltage and Current analog inputs
