The MEMOLUB® 24VDC-PLC model lubricator is
especially designed for PLC-controlled machinery (or
mobile equipment) where a 24VDC power supply is
available. It is ideal for lubricating a wide variety of
robots, conveyors, and OEM applications. The
MEMOLUB® 24VDC-PLC can be direct-mounted for
single-point applications, or remote-mounted using pipe
or flexible tubing. In addition, lubrication from 2 to 12
lube points is possible with a MEMOLUB® Multi-Point
Lubrication System.
PLC-Controlled Lubrication
The MEMOLUB® 24VDC-PLC lubricator has a unique design utilizing a Power-Through Memo which
contains the electrical connections needed to power the unit. This gives the user the ability to quickly
remove the lubricator for fast lubricant cartridge change-out while avoiding contact with the electrical
connections. A 5-foot extension cable on the Power-Through Memo is connected to a PLC-controlled
power supply. The PLC program controls the frequency of lubrication output cycles, which may be based
upon elapsed clock hours, machine cycles, a count of parts produced, or other desired criteria. Further
control is provided by adjusting the volume of lubricant ejected on each cycle. A set of 8 special stroke-
limiting washers are supplied with each lubricator. When the Power-Through Memo is used without
washers (yielding full piston stroke), the output volume at each stroke is 0.635cc. For each washer
The MEMOLUB 24VDC-PLC is available in three sizes: the Standard (Model 120), the Mega (Model 240),
and the Giga (Model 480). Like the HPS model, it is reusable with available replacement lube cartridges.
These cartridges are carefully filled at the factory using a precise centrifuging process that eliminates air
pockets and contamination. Cartridge change-out normally takes less than 60 seconds! MEMOLUB® is a
valuable alternative to time-consuming and costly manual lubrication.

(including the "C"-shaped lock washer) inserted into the
brass adapter of the Power-Through Memo, the output
volume is decreased by 0.04cc per stroke.
(
Note: The lock washer should always be inserted last to hold the others in place.)
