The positioner TRP102 is used for the remote control of modulating actuators or for use as a minimum positioner (providing a bottom limit for the output signals from modulating controllers). The control range is 0 ... 100% of the rotation of the actuator
Application
The positioner receives its power supply through terminals 1 and 2. The position to which the rotary knob is turned produces a proportional control signal Y of either 0...10 VDC or 2...10 VDC at the output (Terminal 3) and thus a proportional change in the position of the actuator between 0...100%. The change-over from 2...10V- to 0...10V- is effected by means of a slide switch on the p.c.b.
