INTRODUCTION

The MOC2XXX series of motor operated controls consists of a motor-driven,

variable potentiometer and the limit switches required to provide remote

adjustment of resistance or voltage. MOC2XXX controls can be specified for

ac or dc operation with 24-, 32-, 48-, or 120-volt control power.

MODEL NUMBER DEFINITION

The model number for this series of MOCs consists of the prefix MOC2

followed by three digits. The first digit establishes the input control voltage.

The second and third digits establish the output control element characteristics.

Table 1 lists the available model numbers and the corresponding operating

characteristics. For example, MOC2305 has a 32 Vdc control input and a 500

ohm, 2 watt potentiometer.The MOC2 Motor Operated Potentiometer is a

motor-driven control device

designed to provide remote adjustment of resistance or voltage in power

system and control applications.

The MOC series combines a variable potentiometer with integrated limit

switches, enabling precise remote control while ensuring dependable

operation. Available in configurations supporting AC or DC operation with

24 V, 32 V, 48 V, or 120 V control power, the MOC2 offers flexibility for a

wide range of installation requirements.

Ideal for generator control, excitation systems, and industrial power

applications, the MOC2 simplifies remote setpoint adjustment and enhances

operational convenience. Its robust design and versatile control power

options make it a reliable solution for applications requiring accurate and

repeatable voltage or resistance control from a remote location.
