Overview

About the LiftMaster MAXUM JDC

The LiftMaster MAXUM JDC is a next-generation DC jackshaft commercial door operator. Compared with classic Logic 5.0 industrial (J/H), MAXUM is built around a 24VDC motor, soft start/stop, faster average travel (about 12″ per second on sectionals), a floor-level LCD control, and built-in Wi-Fi for myQ Facility diagnostics. Side-mounts for high-lift or vertical-lift sectionals and many rolling applications — without the hoist package (see JHDC for hoist, RJDC for manual-release jackshaft).

Why MAXUM vs classic Logic 5.0

Faster average travel — about 12″/sec on many sectionals (vs classic industrial packages)
Floor-level LCD setup & diagnostics — less ladder time for programming and errors
Built-in Wi-Fi / myQ Facility — remote status, cycle counts, maintenance insights
Soft start / soft stop — quieter, gentler on the door system
Dual handing — one unit covers left or right installs

Classic Logic 5.0 J /
H /
T remain strong workhorses — MAXUM is the next-gen option when speed and connected diagnostics matter.

When to choose JDC

Pick JDC for MAXUM jackshaft without a hoist. Need floor-level hand chain? JHDC. Manual-release jackshaft? RJDC. Standard-lift ceiling trolley? TDC. Classic Logic 5.0 still available as J/H/T.
