Design and principle of operation
– Potentiometers POT R1 and POT R2, position transmitter ESR
The actuator can be equipped with two potentiometers POT R1 and POT R2
or
In Types SAM-20 to -52 only, a position
transmitter ESR with an output signal of 4(0)
to 20 mA.
Both versions enable remote analog transmission of the valve stem position.
The potentiometers and the electronic position transmitter are preset to the required
travel, but they can be changed if required
(refer to section 8).

– Positioner PEL 100
The actuator can already be equipped with
a positioner at SAMSON (see section 10).
Input signals:
0(4) to 20 mA or
0 to 10 V
When the actual value deviates from the set
point, a signal (manipulated variable) is
generated to control the actuator.
