The following information applies to the standard and enhanced versions of the modulating actuators.

Characteristic function
GMA163.1, GMA164.1

Offset Uo and span ΔU can be adjusted using two potentiometers (see 3.4 "Adjustable characteristic function"). The maximum permissible input voltage (Uo + ΔU) is DC 35 V.

Application

Actuators featuring this function can be used for the following applications:

  • Dampers with a rotary angle limitation, for instance in the 0°...45° range, can be controlled using the full positioning signal range DC 0...10 V.

  • As a sequencing actuator in control loops that can only apply a DC 0...10 V positioning signal to control more than one sequence.

  • In control systems with a positioning signal deviating from DC 0...10 V such as
    DC 0…35 V.
