It can be very expensive to automate older control systems containing manually controlled potentiometers, rheostats or rotary cam switches.
It can be very expensive to automate older control systems containing manual-controlled potentiometers, rheostats or rotary cam switches.
However, Micronor's MR267 offers a simple and inexpensive solution using commonly available 4-20mA loop control.
The MR267 provides a 4-20mA current loop controller (CLC) option for Micronor's line of motorised potentiometers.
The CLC option can be supplied as part of any configuration of Micronor's MR200 series modular cam switch system and MPxx Series motor pots.
Motor pot options include one- or 10-turn potentiometers, pot ratings from 2 to 170W, composite or wirewound, time periods from 5 seconds to 24 hours, and cam switch channels from 0 to 24.
There are also electromechanical or optical switches, single and dual programmable cams, and open, closed or heavy duty (NEMA 4/4X) enclosures.
Mounting can be DIN-rail or panel.
Four selectable modes of operation cover standard 4-20mA current loop control, 0-20mA current loop control, 0-2.5V voltage control and control via external potentiometer.
Motorised potentiometers are used in a variety of industrial automation and process control applications.
They are simple to use, easy to set up (no computers required.) and have no software programs to write.
The onboard control provides absolute positional feedback information or function as the variable resistor in an analogue control or bridge circuit.
A motorised potentiometer provides a smooth uniform ramp throughout its timing cycle.
Rotary limit switches are programmed (via the cams) to electrically control events (or provide status) at pre-set stages.
Applications include ramping up the field current of a DC motor or controlling the start-up of a generator.
