MODULATOR

SD-13-4830

DESCRIPTION

The Bendix

M-30

™

modulator replaced both the M-21

™

(Figure 2) and M-22

™

(Figure 3) modulators in all applications.

The M-30

™

antilock system modulator (Figure 1) is a high

capacity, on/off air valve that incorporates a pair of electrical

solenoids for control. The solenoids provide the electro-

pneumatic interface between the antilock controller

electronics and the air brake system. The modulator is

used to control the braking function on individual or dual

service actuators during antilock activity. When used to

control both service chambers on an axle or two chambers

on the same side of a tandem axle, the modulator is

sometimes mounted ahead of a quick release valve, which

provides quick exhaust of service applications during normal

braking (Figure 4). In the case of individual wheel control

applications, the modulator is always the last control valve

through which air passes on its way to the service brake

actuator.

The modulator consists of a die cast aluminum body and a

solenoid assembly which contains one normally open

solenoid, one normally closed solenoid, and an inlet and

exhaust diaphragm valve. A three pin, weather resistant

electrical connector is an integral part of the modulator

solenoid assembly and serves to carry control commands

from the antilock controller to the modulator. Two mounting

holes are provided for frame or cross member mounting of

the valve.
