Industrial Applications

1. High-density machine output control

Drives 32 discrete sinking loads from a compact CJ PLC rack, ideal for solenoids, relays, and indicator stacks where many outputs must fit in limited panel space.

Problem Solved

Reduces rack footprint while increasing discrete output count without external relay expansion.

2. Fast actuation of small DC loads

Supports rapid switching with 0.1 ms ON and 0.8 ms OFF response, making it suitable for high-cycle automation tasks with short pulse timing.

Problem Solved

Minimizes command-to-output delay in repetitive sequencing and timing-sensitive control.
