Modutrol IV Motors

The M7161, M7164 and M7184 Electronic

Modutrol Motors provide proportioning control
of zone dampers and valves when used with
modulating dc voltage input.

M7161 and M7164 replace M734H,J Motors and
Ranco LA2-1000 and 2000 Linear Actuators.

M7184 replaces M744D Motors.

M7161, M7164 rated for 35 lb-in. torque.

M7184 rated for 150 lb-in. torque.

M7164G is electrically normally open; all other
motors are electrically normally 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 Vac.
Models available with factory installed transformer,
or an internal transformer can be field added.

Quick-connect terminals standard—screw termi-
nal adapter available.

Adapter bracket for matching shaft height of older
motors is standard with replacement motors.

Nominal timing of 30 seconds for 90

°

 stroke and

60 seconds for 160

°

 stroke.

Valve and damper linkages, explosion proof hous-
ing, and auxiliary switches available as accessories.

Die-cast magnesium housing.

Used with Honeywell W7080 Multizone System.
