Motors
Model: M9181A-1012 Honeywell Inc.
Features: Reversing, proportional motors used to operate
valves or dampers in electric modulating circuits. Oil immersed
motor and gear train for reliable performance and long life.
Wiring box provides NEMA 3 weather protection. Actuator
motor and circuitry operate from 24 volts AC. Fixed stroke,
160
o .
No auxiliary switches. The controller type is a 135 ohm
Honeywell Series 90 proportional controller (See Fig. 10).
Model: M7284A-1020 Honeywell Inc.
Features: Electronic Modutrol motors used to control dampers
and valves. This motor accepts a current signal from an
electronic controller to position a damper of valve at any point
between open and closed. Oil immersed motor and gear train
for reliable performance and long life. Wiring box provides
NEMA 3 weather protection. Actuator motor and circuitry
operate from 24 volts AC. Fixed stroke, 160
o
. No auxiliary
switches. This motor is used with controllers that provide a
stable, noise-free proportional output of 4-20mA nominal,
25mA maximum (See Fig. 13).
Model: M6281A-1009 Honeywell Inc.
Features: Floating control motor with an internal electrically
isolated feedback potentiometer. This motor is used with
controllers that provide SPDT or floating output to operate
dampers or valves. The feedback potentiometer provides an
indication of the motors shaft position and can be used for
slaving Series 90 motors or rebalancing an external control
circuit. Wiring box provides NEMA 3 weather protection. Actua-
tor motor and circuitry operate from 24 volts AC. Fixed stroke,
160
o
. No auxiliary switches (See Fig. 12).
Model: M6191B-1006 Honeywell Inc.
Features: Non-spring return, 3-wire floating control motor. This
motor is used with controllers that provide a switched or floating
SPDT output to operate dampers or valves. Actuator motor
and circuitry operate from 24 volts AC. Fixed stroke, 160
o
. One
(1), auxiliary switches (See Fig. 14).
Model: M150-JGA-1 Penn Johnson
Features: The M100J motor actuators are used to position
valves and dampers in heating ventilating, air conditioning,
refrigeration and industrial applications. The motor accepts a
Johnson Controls 0 to -2 VDC electronic controller input, or a
0 to +24 VDC input, or a 3-wire 135 to 1000 ohm potentiometer
input (See Fig. 11).
