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.
