PRODUCT DESCRIPTION
e potentiometer uses a supply of 230 VAC, and gives a stepless output signal
(1—10 VDC, 2—20 mA or 10—100 % PWM). e minimum output values can be
adjusted within 1—7 VDC / 2—14 mA / 10—70 % PWM, and the maximum values
- within 3—10 VDC / 6—20 mA / 30—100 % PWM. ere is an additional switch
on/off function (e.g. for controller remote on/off).
